In this research, yarrow phenolic-rich extract was produced using pulsed electric field (PEF)-ultrasound assisted technology. The highest extraction efficiency (5.99 %) was obtained at 6.25 kV/cm of PEF and the sonication time of 60 min. As the PEF intensity and sonication time rose, the total phenolic content (TPC) and ferric-reducing power (RP) of the extracts increased. The PEF intensity of 2.70 kV/cm and sonication time of 45.83 min were the optimum extraction conditions resulting in the highest extraction efficiency, TPC, and RP. Then, this optimum extract was loaded into nanoliposomes. At higher extract levels, the encapsulation efficiency lowered, while the particle size, polydispersity index (PDI), and zeta potential of the nanoliposomal samples elevated. The results of Fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) confirmed the successful encapsulation of yarrow extract into nanoliposomal carriers; the sample containing the extract had the highest enthalpy (3600 J/g) and nanoliposomes loaded with yarrow antioxidant extract (0.11 mL/mg) was the optimum sample. Finally, the sesame oil containing 500 ppm free and nanoliposome extract, as well as the sample with 200 ppm BHT were evaluated for oxidative stability. The highest oxidation stability (14.21 h) belonged to the oil containing nanoliposomal yarrow phenolic extract.

Jujube, a fruit rich in phenolic compounds, is renowned for its potential health benefits, including lowering blood pressure, and exhibiting anti-cancer, and anti-inflammatory effects, attributed to its potent antioxidant properties. However, the application of these phenolics in food products is limited by their instability and low concentration in plant tissues. This study investigates the nanoencapsulation of jujube extract (JE) using nanoliposomes (NLs) coated with pea protein isolate (PPI) to enhance stability and bioavailability. NLs were prepared via the ethanol injection method and optimized through comprehensive characterization, including dynamic light scattering, polydispersity index, and zeta potential. The encapsulated JE showed improved antioxidant activity and controlled release profiles in simulated gastric fluid and simulated intestinal fluid. This research highlights the potential of PPI-coated NLs in stabilizing and enhancing the bioactivity of jujube phenolics, providing a promising approach for their integration into functional foods.

In this study, we investigated the combined impact of monoacylglycerol (MAGs) and methylcellulose (MC) on the production of hybrid oleogels. Since cellulose derivatives are inherently hydrophilic substances, they require dissolution in oil through an emulsion-coating method. Therefore, we developed a hybrid oleogel utilizing MAGs and MC. Initially, a hybrid oleogelator was created by blending an aqueous MC solution into fully melted MAGs to form MC in water-in-MAGs emulsions with varying MC/MAG ratios, followed by drying. Subsequently, the resulting oleogelator was mixed with rapeseed oil to produce oleogels, and their properties were compared with oleogels produced solely with MAG oleogelator. The findings indicated that the obtained oleogelator did not significantly impact the oxidation of the oleogels. Additionally, there was no notable difference observed in the induction period of crystallization and the crystallization rate of the oleogels. Microscopic images revealed that the hybrid oleogel structured with a 30:70 ratio of MAGs and MC contained the lowest liquid phase percentage. In terms of rheological assessment, the hybrid oleogels exhibited solid-like behavior, consistent with polarized light microscopy (PLM) images. Furthermore, based on the three-interval thixotropic test (3-ITT), the hybrid oleogels displayed higher recovery compared to the control sample.

The objective of this study was to evaluate the release of oleuropein (OLP) from double nanoemulsions stabilized with polymeric complexes. Initially, W1/O nano-emulsions loaded with OLP were prepared and re-emulsified into an aqueous phase (W2), which included a complex of whey protein concentrate (WPC)/pectin, to form W1/O/W2 emulsions. The microstructure of the final double emulsions was analyzed by scanning electron microscopy (SEM), and particles with smooth, comparatively spherical, and somewhat asymmetrical surfaces with a size range of 100–200 nm were observed, which were compatible with dynamic light scattering (DLS) data. The release trend of OLP was determined by fitting it to several empirical models including zero order, first order, Higuchi, Hixson-Crowell, Korsemeyer-Peppas, Baker-Lonsdale, and utilizing intelligent modeling techniques such as Fuzzy Logic (FL) and Artificial Neural Networks (ANNs). Among the mathematical models, the zero order equation had the highest coefficient of determination (R2 = 0.988), while the first order equation had the lowest root-mean-square error (RMSE = 0.0176) and sum of squared errors (SSE = 0.0009) for the goodness of fit of the model, when considering the release trend of OLP. FL and ANNs proved effective in modeling controlled release of OLP-loaded nanocarriers, achieving high R2 values. Additionally, Monte Carlo (MC) simulation showed potential for evaluating the release process when compared to other methods.

Abstract This study aimed to investigate the biological activities of Lactobacillus gasseri SM 05 (L. gasseri) and Lacticaseibacillus casei subsp. casei PTCC 1608 (L. casei) in the black raspberry (Rubus dolichocarpus) juice (BRJ) environment, and also the anti-adhesion activity against Salmonella typhimurium (S. typhimurium) in fermented black raspberry juice (FBRJ). Results showed significant anti-adhesion activity in Caco-2 epithelial cells. In the anti-adhesion process, lactic acid bacteria (LAB) improve intestinal health by preventing the adhesion of pathogens. Adding LAB to BRJ produces metabolites with bacteriocin properties. Major findings of this research include improved intestinal health, improved antidiabetic properties, inhibition of degradation of amino acids, and increase in the nutritional value of foods that have been subjected to heat processing by preventing Maillard inhibition, and inhibition of oxidation of foodstuff by increased antioxidant activity of BRJ. Both species of Lactobacillus effectively controlled the growth of S. typhimurium during BRJ fermentation. Moreover, in all tests, as well as Maillard's and α-amylase inhibition, L. gasseri was more effective than L. casei. The phenolic and flavonoid compounds increased significantly after fermentation by both LAB (p

Pseudomonas aeruginosa is a Gram-negative human pathogenic bacterium that has the ability to form multicellular biofilm (BF) communities. Due to the presence of extracellular polymeric substances, BF protects bacteria from unfavorable environmental conditions and causes their resistance to antimicrobial substances. The presence of BF in the food industry has become a great threat to food safety. Conventional disinfection technologies are inappropriate for effective BF control due to the resistances created to them and the toxic residues for humans and the environment that they leave behind. Therefore, it is necessary to understand more about the formation and development of BF and environmentally friendly methods to remove BF from food and equipment in contact with food. This review article describes BF formation, its resistance mechanisms to antimicrobial agents, and BF development. Also, novel and effective strategies involved in BF removal are discussed including physical methods (plasma, pulsed electric field and ultrasonication), physicochemical method (electrolyzed water), biological methods (enzymes and bacteriophages), natural compounds such as essential oils, and application of nanomaterials.

Many studies have demonstrated the health and functional benefits of bioactive compounds (bioactives), as delivery of these ingredients to the body have been conducted by different techniques, such as enriched foods, supplements, etc. Among these, chewing gum (CWG) could be a unique candidate as delivery matrix of bioactives since presents some inherent benefits, including protective feature of its matrix as encapsulants; improving concentration, memory and alertness; stress reduction, weight manage, easy to use anytime and anywhere, and desired by consumers, especially children. Moreover, the specific style of CWG consumption, i.e. continued chewing without swallowing provides a unique opportunity to local and systemic delivery of bioactives in a sustained release manner, and the stability and activity of bioactives could be controlled by changes in the ingredients and manufacturing procedure, or using encapsulation technique. This review deals with introduction of bioactives in terms of chemical structure, health benefits, limitations for practical effectiveness, followed by highlighting the role of CWG as a delivery system of bioactives. Taking these into account, CWG composition and manufacturing procedures were reviewed, and developments in vitro delivery of encapsulated bioactives by CWG matrix were discussed. In this regard, more studies should be performed to monitor the release behavior of different bioactives from CWG as affected by various factors. Finally, further studies direct us to produce an optimum CWG formulation providing targeted outputs in line with consumer interests, namely good taste, practical efficiency, low price and lack of environment pollution.

Application of controlled fermented sprouted legumes is important in terms of improving quality and shelf-life of wheat bread. In the present study, after spontaneous fermentation of sprouted mung bean containing ginger extract (GE), the predominant lactic acid bacteria (LAB) isolates were screened based on their inhibitory activity against Aspergillus niger. Sequencing results of the PCR products led to the identification of Levilactobacillus brevis as the selected isolate with 73.12% antifungal effect. Then, the selected isolate was used as a protective starter culture in the controlled fermented sprouted mung bean (FSM). Production of wheat bread with FSM containing a protective starter culture and GE not only improved the textural features of the product, but also increased its mold-free shelf-life. Accordingly, wheat bread containing FSM and GE with crumb hardness of 9.52 N, specific volume of 3.53 cm3/g and weight loss of 15.95% had the most appropriate textural characteristics with the lowest fungal surface expansion (45.52% mold growth) after 7 days storage in a challenge test. Furthermore, there was no significant difference (P > 0.05) between this sample and control bread in terms of overall acceptability.

Although several fundamental applications have been reported for yeast cells and their components as functional vehicles or promising structural ingredients in encapsulation of bioactive compounds; meanwhile, potential applications of encapsulated yeasts (EYs) have been less reviewed. Recently, EYs have received increasing attention for industrial applications in different areas of biotechnology such as bioremediation of toxins or heavy metals, bio-filtration, and biocatalyst or bioethanol production. Yeast cells are mostly encapsulated within alginate, chitosan, and some other polysaccharide-based coating materials. These platforms enable us to enhance survivability of probiotic yeasts in food, feed and gastrointestinal transit, as well as to improve their mucoadhesion and targeted delivery. Furthermore, increased thermo-tolerance and stability of yeasts towards high concentrations of alcohols, as well as their improved yield during industrial processing of different fermented foods have been revealed using encapsulation strategies. These cost-effective and scalable matrices have also several innovative potentials to construct composite of living cells and engineered polymers or cell-in-shell hybrids in order to modify techno-functional and sensory properties of the product, as well as cell immobilization, cell-surface engineering and programmed intelligent coating formation and/or degradation.

The aim of this study was to stabilize the antioxidant compounds of thyme (Thymus vulgaris) extract by spray-drying process and MD, WPC and MD-WPC carriers at different temperatures (120 and 150°С). Then, the optimal encapsulated sample was used in different ratios (1, 2, 3 and 5% w/w) to fortify pan-breads. The highest production yield (∼68 %) was obtained in the extract encapsulated with MD-WPC at 150°С. The values of moisture (3.2–4.1 %) and water activity (0.28–0.33) indicated the microbial stability of the powders. The functional characteristics of the particles (solubility and wettability) were affected by the composition and nature of the carriers. Also, the use of WPC led to an increase in physical stability, encapsulation efficiency (∼84 %), TPC (4.4 mgGAE/g) and antioxidant activity (∼77 %). The results of SEM and staining of the samples respectively indicated the effect of the process parameters on the morphology and the placement of the phenolic compounds within carrier's matrix. The physicochemical, textural characteristics, color indices (crumb and crust) and antioxidant activity of fortified breads were affected by the ratio of added free and spray-dried extract. The evaluation of sensory indices (color, texture, chewiness, taste and overall acceptance) indicated the ability to fortify bread with 3 % spray-dried extract.

Microencapsulation protects lactic acid bacteria against adverse conditions of environment and gastrointestinal tract and increases their survival. This study was conducted with three treatments, namely control, alginate-L. brevis (AL-LAB), and alginate-chitosan-L. brevis (AL-CHI-LAB). The results showed that the zeta-potential for microcapsules fixed by AL-CHI–LAB and AL–LAB were -16.5 and -17.2 mV, respectively. The SEM images showed cubic and non-aggregated structures for three types of microcapsules. The significantly highest survival rate for the AL-CHI-LAB observed in the GIT simulated conditions (59/50 %), and the significantly highest survival rate for the AL-LAB at the in vivo conditions of the GIT (50 %). To investigate SOD and GPX gene expression levels in roosters' testicular tissues, L. brevis was fed (106 CFU/g) to thirty-two roosters aged about 60 weeks for two months. The GPX gene expression level in the testicular tissue was higher in the AL-CHI-LAB (6.57) than other treatments and it was not significantly different from the AL-LAB (4.09). The SOD gene expression was not significantly different among treatments. The results indicated that AL-CHI-LAB could improve the antioxidant capacity of testicular tissues by increasing the GPX gene expression, thereby improving aging-related reproductive performance.

Due to the increasing interest in the healthy foods, in this research, a dietary and functional confectionary cream (DFCC) was produced having licorice powder and encapsulated Lactobacillus plantarum probiotic bacteria. Licorice extract (LE) had a total phenolic content of 1.97 mg/mL, composed mainly of 7 phenolic, flavonoid, and quercetin compounds including gentisic acid, caffeic acid, p-coumaric acid, ferulic acid, luteolin, apigenin, and sinapic acid at the same concentration (20 µg/mL). Incorporation of LE and malva mucilage (MM) resulted in the improvement of physicochemical properties (pH, overrun, syneresis, and texture) of DFCC. The viability of encapsulated probiotics was higher (compared to the free probiotics) in the functional product during 60 days of storage. Sensory evaluation results displayed that the elevated rates of LE (15 %), and MM (15 %) were not favorably accepted by the panelists; however, favorable scores were given to the samples having 10 % LE, 10% MM, and microcapsules.

Nanoencapsulation of thyme essential oil (TEO) volatiles into β-cyclodextrin (β-CD) and their release requires in-depth kinetic, structural and in silico studies for elucidating the mechanisms for attaining the equilibrium state. Monoclinic crystalline structures of β-CD/TEO with 5 –10 μm were formed by TEO encapsulation and visualized using SEM. The β-CD:TEO 8.5:1.5 (w/w) ratio ensures 71.66% TEO retention efficiency and a cumulative release in hexane after 7 h of 75%. Thymol molecule is the favourite candidate to occupy the inner cavity of β-CD, although competition by carvacrol, o-cymene, 2-carene and camphene against thymol was noticed by GC/MS when increasing the TEO concentration. The molecular mechanics calculations suggested that binding of thymol, carvacrol and o- cymene within the hydrophobic cavity of β-CD is thermodynamically achievable, having complexation energy between -18.48 ÷ -22.07 kcal/mol, nonetheless the most stable complex is formed with α- pinene, if energy input is provided, displaying the lowest complexation energy, -25.89 kcal/mol. All inclusion complex (IC) powders had similar antiradical activity against DPPH (40 - 43%). The IC2 β-CD/TEO 8.5:3.00 (w/w) powder displayed antibacterial activity against Bacillus cereus, while IC3 β-CD:TEO 8.5:1.50 (w/w) exhibited the strongest antifungal activity of all powders against Geotrichum candidum and Rhodotorula glutinis. The ICs obtained suggest a competitive mechanism of TEO components in occupying the β-CD inner cavity that predispose each powder formulae for specific applications in food in relation with their functional properties.

Abstract This study aimed to produce bioactive peptides from navy-bean protein with alcalase and pepsin enzymes (30–300 min) and to load them into a nanoliposome system to stabilize and improve their bioavailability. The degree of hydrolysis and biological activities (scavenging of DPPH, OH, and ABTS free radicals, reducing power, and chelating metal ions) of navy-bean protein were affected by the type of enzyme and hydrolysis time. The average particle size (83–116 nm), PDI (0.23–0.39), zeta potential (− 13 to − 20 mV), and encapsulation efficiency (80–91%) of nanoliposomes were influenced by the type and charge of peptides. The storage temperature and the type of loaded peptide greatly affected the physical stability of nanocarriers and maintaining EE during storage. The FTIR results suggested the effect of enzymatic hydrolysis on the secondary structures of protein and the effective placement of peptides inside polar-regions and the phospholipid monolayer membrane. SEM images showed relatively uniform-sized particles with irregular structures, which confirmed the results of DLS. The antioxidant activity of primary peptides affected the free radical scavenging of loaded nanoliposomes. Liposomes loaded with navy-bean peptides can be used as a health-giving formula in enriching all kinds of drinks, desserts, confectionery products, etc. Graphical Abstract

Abstract There are differing views on cannabis and phytocannabinoid usage in diverse domains of application. This review explores the advantages and drawbacks of using cannabis and phytocannabinoids, including their effects on human health, in addition to highlighting the need for precise and repeatable analytical methods for quantifying controlled phytocannabinoids in consumer cannabidiol (CBD) products and foods. The composition and characteristics of the phytochemicals found in cannabis, the advantages and disadvantages of controlled and uncontrolled phytocannabinoids, and the need for regulation and standardization in the use of cannabis and products containing phytocannabinoids are all covered in this review of the pertinent literature. Cannabinoids used illegally can have negative consequences, but controlled phytocannabinoids found in consumer CBD products are relatively safe and unlikely to cause any adverse effects. It is necessary to restrict the amount of CBD in foods and consumer products in order to ensure safety. To measure the amount of restricted phytocannabinoids in these products, accurate analytical techniques are also required. In order to increase the use of cannabis among consumers, more research is needed to improve our understanding of the bioavailability and metabolic pathways of these compounds. Furthermore, consumers want clear and uniform federal rules governing the amount of CBD in food products in order to ensure correct dosing. To promote safe and responsible use, cannabis and phytocannabinoids must be carefully considered, regulated, and standardized. It is necessary for consumers to have clear, consistent standards governing the percentage of CBD in their food products. As a result, they would know the exact amount of CBD in their products.

This paper focuses on the combination of gelatin (Gel), pectin (Pec), and Pistachio peel anthocyanins (PSAs) to develop a halochromic film for food applications (shrimp). The results of spectroscopic properties showed that the film components had proper interaction and compatibility. Furthermore, the addition of PSAs and Pec improved the thermal stability of films. The addition of Pec and PSAs significantly improved the physical properties and mechanical resistance of the films. So that, the permeability to water vapor and oxygen reduced from 2.81 to 2.74 (g‧s−1‧Pa−1‧m−1) and 5.25 to 4.70 (meq/kgO2), respectively. In addition, the strength and flexibility of halochromic film reached 0.7 MPa and 56 % compared to Gel film (0.62 MPa, and 46.96 %). Most importantly, the color changes of the smart film from cherry/pink to yellow/brown, which were proportional to the color changes of the anthocyanin solution at different pHs, were able to monitor the shrimp freshness and spoilage at room (20 °C) and refrigerated (4 °C) temperature for 14 days.

This study aimed to investigate the modeling of antimicrobial activity (AA) of nisin and sorbate on Clostridium sporogenes in jar cream cheese (JCC) using the linear regression (LR), multilayer perceptron (MLP) neural network, and reduced error pruning tree (REPTree) methods, in order to prevent the late blowing defect (LBD) in the cheese. Both preservatives used in JCC samples showed AA against C. sporogenes; so that sorbate at all the concentrations used in JCC samples inhibited cracking spoilage during storage period at 35 °C. However, nisin could not inhibit cracking spoilage at concentration of 30 ppm in the samples, and a higher concentration of it was needed. The three models used in this study, followed the similar pattern in both training and validation datasets for nisin and sorbat in JCC. The R2 and root mean square error (RMSE) values of training and validation datasets showed the superiority of the REPTree model compared to the MLP and LR models (conventional methods) in the modeling of AA of nisin and sorbate against C. sporogenes in JCC.

This research aimed to assess the impact of ultrasonication on the emulsifying ability of a conjugate system composed of sodium caseinate and soluble soy polysaccharides. The study analyzed the characteristics of the particles and evaluated the emulsions produced using nanoconjugates. The results showed that ultrasonication improved the contact angle (63.7°) and decreased particle size (75 nm), resulting in more effective emulsifying efficiency. At a 2 % concentration of the nanoconjugates, stable emulsions with a 50 % oil content were successfully formed through complete coverage of the droplets' surface, and no oil release was observed. Moreover, the emulsions’ creaming index remained below 25 % even after 60 days of storage. The stability of the nanoconjugate-based emulsions depended on the concentration of nanoconjugates, with an optimal concentration of 4 %. These findings suggest that the nanoconjugates have great potential as a natural stabilizer for emulsion-based products.

Sodium copper chlorophyllin (SCC), with a higher stability and water solubility than chlorophyll, has limited applications in acidic products due to precipitation. We investigated the effect of pectin (PE), carboxymethyl cellulose (CMC), xanthan gum (XG), carrageenan gum (CG), gellan gum (GG), tragacanth gum (TG), gum Arabic (GA), and polysorbate 80 (PS80) on SCC stability in acidic model solutions (pH = 3.5). These stabilizers led to a significant reduction in particle size and zeta-potential compared to control sample. GA (33.3:1), PE (8:1), CMC (4:1), XG (1.33:1), and PS80 (0.67:1) stabilized SCC in acidic systems for 28 days. The FTIR analysis showed that mainly electrostatic and hydrogen bonds between SCC and stabilizers led to a substantial decline in particle size, improving SCC distribution and stability within acidic environment. Thus, XG and CMC could be effectively used for SCC stabilization under acidic solutions where applying PS80 surfactant is a health concern.

Conjugated linoleic acid (CLA) has recently attracted significant attention as a health-promoting compound. CLA is a group of positional isomers of linoleic acid (LA) with a conjugated double bond naturally occurring in dairy and ruminant meat products. Microbial biosynthesis of CLA is a practical approach for commercial production due to its high safety and purity. There are some factors for the microbial CLA production such as strain type, microbial growth phase, pH, temperature and incubation time, based on which the amount and type of CLA can be controlled. Understanding the interplay of these factors is essential in optimizing the quantity and composition of microbial CLA, as discussed in the current study. Further exploration of CLA and its influences on human health remains a dynamic and evolving area of study.

In this study, the spray-drying process of Chlorella extract was investigated. The influence of different carriers including maltodextrin (MD), acacia gum (AG), whey protein concentrate (WPC) on the physicochemical, functional, flowability and color properties was analyzed. Powder obtained using MD revealed the highest bulk and tapped density (0.613 and 0.750 g/mL, respectively), the highest solubility (96.87 %) and hygroscopicity (29.87 %). Dry powder attained by MD, showed the highest content of total phenols (0.413 mg GAE/mL) and lowest particle size (12.70 μm). All produced powders revealed fair to good cohesiveness and flowability. Besides, the spray-drying processes using (MD -WPC) showed higher maintenance of the antioxidant activity. SEM images revealed the presence of particles of different sizes and wrinkles. Evaluation of the chemical structure (FTIR) indicated the encapsulation and distribution of the phenolic compounds of the extract in the matrix of the carriers. Research findings can confirm the possibility to use encapsulated Chlorella extracts as an abundant source of natural antioxidants in the enrichment and formulation of various beneficial food products. Finally, the results showed the efficiency of the spray-drying process on the production of dry powder extract of Chlorella with appropriate physical properties, stability and antioxidant properties.

Water-in-oil (W/O) Pickering emulsions (PEs) as delivery systems have recently attracted important research efforts. The lack of food-grade hydrophobic particulate as emulsion stabilizers is the most important challenge in this field. This study investigates the surface modification of silica (SiO2) nanoparticles (SNPs) by chitosan and their role in formulation and stabilization of PEs; namely, the adsorption of chitosan on the surface of SNPs through electrostatic attraction with different chitosan/SiO2 ratio and pH values. The ability of SNPs to stabilize water in oil PEs regarding this modification was then investigated. The interaction between SNPs and chitosan was characterized by zeta potential, wettability, FTIR, Energy dispersive X-ray mapping analysis (EDX- MAP) and nitrogen absorption/desorption isotherm. The results confirmed that the surface modification of SNPs by chitosan had a significant impact on zeta potential and on the wettability of SNPs. Finally, modified SNPs were applied to the formulation of PEs; we identified the optimized conditions that increase the emulsion formulation process and stability. Therefore, modified SNPs by chitosan in this study could act as food-grade W/O Pickering stabilizers to fabricate environmental-friendly emulsion products.

Electrospun fibers (EFs) have emerged as promising one-dimensional materials for a myriad of research/commercial applications due to their outstanding structural and physicochemical features. Polymers of either synthetic or natural precursors are applied to design EFs as carriers for bioactive compounds. For engineering food systems, it is crucial to exploit polymers characterized by non-toxicity, non-immunogenicity, biocompatibility, slow/controllable biodegradability, and structural integrity. The unique attributes of protein-based biomaterials endow a wide diversity of desirable features to EFs for meeting the requirements of advanced food/biomedical applications. In this review paper, after an overview on electrospinning, different protein materials (plant- and animal-based) as biodegradable/biocompatible building blocks for designing EFs will be highlighted. The potential application of protein-based EFs in loading bioactive compounds with the intention to inspire interests in both academia and industry will be summarized. This review concludes with a discussion of prevailing challenges in using protein EFs for the bioactive vehicle development.

Background and Objective: Essential oils include low solubility, poor bioavailability and rapid release, which may limit their use as bioactive compounds in foods and medicine. Nanoencapsulation can preserve inherent qualities of essential oils and improve their physicochemical characteristics and health benefits. Focus of the present study was on the loading of essential oils from Zataria multiflora in pickering nanoemulsions, nanoparticles and nanophytosome. In addition, the present study assessed how these systems affected their physicochemical characteristics and antioxidant and antimicrobial activities, compared to free-essential oils. Material and Methods: Encapsulation of Zataria multiflora Boiss essential oil in nanocarriers as a novel phytoconstituents delivery system was carried out using three various methods. Physicochemical characterization of nanocarriers was studied using dynamic light scattering, Fourier transform infrared spectroscopy, field emission scanning electron microscope, confocal laser scanning microscopy, optical microscope and antioxidant activity. The minimum inhibitory and bactericidal concentration assessment effects against Listeria monocytogenes at 24 h and temperatures (10, 25 and 37 °C) were investigated. Encapsulated Zataria multiflora Boiss essential oil with subinhibitory concentrations (0.25, 0.5 and 0.75) in hamburger formulation was selected as a food model for chemical, microbiological and sensory evaluation. Results and Conclusion: In general, this study compared three types of biocarriers with free essential oils. Primarily, nanophytosome showed promising results in delaying oxidation and in antimicrobial and sensory assessments, compared to two other nanocarriers. In conclusion, essential oil nanophytosomes of Zataria multiflora Boiss include the potential as an efficient natural food preservative. Conflict of interest: The authors declare no conflict of interest.

An increased demand for natural products nowadays most specifically probiotics (PROs) is evident since it comes in conjunction with beneficial health effects for consumers. In this regard, it is well known that encapsulation could positively affect the PROs’ viability throughout food manufacturing and long-term storage. This paper aims to analyze and review various double/multilayer strategies for encapsulation of PROs. Double-layer encapsulation of PROs by electrohydrodynamic atomization or electrospraying technology has been reported along with layer-by-layer assembly and water-in-oil-in-water (W1/O/W2) double emulsions to produce multilayer PROs-loaded carriers. Finally, their applications in food products are presented. The resistance and viability of loaded PROs to mechanical damage, during gastrointestinal transit and shelf life of these trapping systems, are also described. The PROs encapsulation in double- and multiple-layer coatings combined with other technologies can be examined to increase the opportunities for new functional products with amended functionalities opening a novel horizon in food technology.

Dairy products are widely consumed in the world due to their nutritional and functional characteristics. This group of food products are consumed by all age groups due to their health-giving properties. One of these products is cheese which has a high price compared to other dairy products. Because of this, it can be prone to fraud all over the world. Fraud in food products threatens the world's food safety and can cause serious damage to human health. There are many concerns among food authorities in the world about the fraud of food products. FDA, WHO, and the European Commission provide different legislations and definitions for fraud. The purpose of this review is to identify the most susceptible cheese type for fraud and effective methods for evaluating fraud in all types of cheeses. For this, we examined the Web of Science, Scopus, PubMed, and ScienceDirect databases. Mozzarella cheese had the largest share among all cheeses in terms of adulteration due to its many uses. Also, the methods used to evaluate different types of cheese frauds were PCR, Spectrometry, stable isotope, image analysis, electrophoretic, ELISA, sensors, sensory analysis, near-infrared and NMR. The methods that were most used in detecting fraud were PCR and spectrometry methods. Also, the least used method was sensory evaluation.

Purpose: This study aimed to investigate the effects of nanoliposomes containing crocin and nisin in milk samples as a food model. Therefore, three formulations were prepared and compared, including (1) milk samples containing free nisin and crocin, (2) samples with nanoliposomes containing nisin and crocin, and (3) nisin and crocin-loaded nanoliposomes coated with chitosan. Methods: In order to find the optimum amount of both bioactives within nanoliposomes, analyses of size, polydispersity index (PDI), zeta potential, and encapsulation efficiency were accomplished. Then, the best formulated nanoliposome was evaluated and compared with a solution containing free bioactives and nanoliposomes coated with chitosan using other experiments, including antioxidant and antibacterial activities, viscosity, colorimetric and bacterial growth. Results: The best nanoliposomal system based on the factors of size, PDI, zeta potential, and encapsulation efficiency was related for the nanocarrier with 4 mg crocin, 4.5 mg nisin, and 40 mg lecithin. Based on the results obtained, both nanoliposome (a*=5.41) and chitosancoated nanoliposome (a*=5.09) solutions could significantly (P

Abstract In this work, selenium nanoparticles (Se NPs) stabilized with cocamidopropyl betaine were synthesized for the first time. It was observed that Se NPs synthesized in excess of selenic acid had a negative charge with ζ-potential of −21.86 mV, and in excess of cocamidopropyl betaine—a positive charge with ξ = + 22.71 mV. The resulting Se NPs with positive and negative charges had a spherical shape with an average size of about 20–30 nm and 40–50 nm, respectively. According to the data of TEM, HAADF-TEM using EDS, IR spectroscopy and quantum chemical modeling, positively charged selenium nanoparticles have a cocamidopropylbetaine shell while the potential- forming layer of negatively charged selenium nanoparticles is formed by SeO3 2− ions. The influence of various ions on the sol stability of Se NPs showed that SO4 2− and PO4 3− ions had an effect on the positive Se NPs, and Ba2+ and Fe3+ ions had an effect on negative Se NPs, which corresponded with the Schulze-Hardy rule. The mechanism of coagulating action of various ions on positive and negative Se NPs was also presented. Also, influence of the active acidity of the medium on the stability of Se NPs solutions was investigated. Positive and negative sols of Se NPs had high levels of stability in the considered range of active acidity of the medium in the range of 1.21–11.98. Stability of synthesized Se NPs stability has been confirmed in real system (liquid soap). An experiment with the addition of Se NPs stabilized with cocamidopropyl betaine to liquid soap showed that the particles of dispersed phases retain their initial distributions, which revealed the stability of synthesized Se NPs.

Pro-and prebiotics have been indicated to modulate the gut-brain axis, which have supportive impacts on central nervous systems, and decrease or control the incidence of some mental disorders such as depression, anxiety, autism, Schizophrenia, and Alzheimer’s. In this review, complex communications among microbiota, gut, and the brain, and also recent scientific findings of the impacts and possible action mechanisms of pro-and prebiotics on mental disorders have been discussed. The results have shown that pro-and prebiotics can improve the function of central nervous system and play an important role in the prevention and treatment of some brain disorders; however, in order to prove these effects conclusively and firmly and to use these compounds in a therapeutic and supportive way, more studies are needed, especially human studies/clinical trials.

Abstract Emerging viruses are known to pose a threat to humans in the world. COVID‐19, a newly emerging viral respiratory disease, can spread quickly from people to people via respiratory droplets, cough, sneeze, or exhale. Up to now, there are no specific therapies found for the treatment of COVID‐19. In this sense, the rising demand for effective antiviral drugs is stressed. The main goal of the present study is to cover the current literature about bioactive compounds (e.g., polyphenols, glucosinolates, carotenoids, minerals, vitamins, oligosaccharides, bioactive peptides, essential oils, and probiotics) with potential efficiency against COVID‐19, showing antiviral activities via the inhibition of coronavirus entry into the host cell, coronavirus enzymes, as well as the virus replication in human cells. In turn, these compounds can boost the immune system, helping fight against COVID‐19. Overall, it can be concluded that bioactives and the functional foods containing these compounds can be natural alternatives for boosting the immune system and defeating coronavirus.

Consumers are increasingly showing a preference for foods whose nutritional and therapeutic value has been enhanced. Probiotics are live microorganisms, and their existence is associated with a number of positive effects in humans, as there are many and well-documented studies related to gut microbiota balance, the regulation of the immune system, and the maintenance of the intestinal mucosal barrier. Hence, probiotics are widely preferred by consumers, causing an increase in the corresponding food sector. As a consequence of this preference, food industries and those involved in food production are strongly interested in the occurrence of probiotics in food, as they have proven beneficial effects on human health when they exist in appropriate quantities. Encapsulation technology is a promising technique that aims to preserve probiotics by integrating them with other materials in order to ensure and improve their effectiveness. Encapsulated probiotics also show increased stability and survival in various stages related to their processing, storage, and gastrointestinal transit. This review focuses on the applications of encapsulation technology in probiotics in sustainable food production, including controlled release mechanisms and encapsulation techniques.

Omega-3 fatty acids play a role in achieving optimal health and in protection against diseases. Although instability and oxidation of its essential fatty acids has limited its use in food products. Among the strategies used to prevent these challenges, the encapsulation technique has been the most successful method. Therefore, in this study, β-cyclodextrin (BCD) inclusion complexes were applied for encapsulation of fish oil and its addition into yogurt for fortification. Physicochemical properties of produced yogurt as well as sensory tests were investigated during 21 days of storage at 4 °C. The results showed that encapsulation of fish oil with BCD significantly reduced the acidity, peroxide value, and syneresis of yogurt while increasing docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). In conclusion, the results demonstrated that yoghurt fortified with encapsulated fish oil has similar sensory qualities to the control sample than yoghurt fortified with free fish oil.

Functional, physicochemical, and rheological properties of protein–polysaccharide complexes are remarkably under the influence of the quality of solvent or cosolute in a food system. Here, a comprehensive description of the rheological properties and microstructural peculiarities of cress seed mucilage (CSM)-β-lactoglobulin (Blg) complexes are discussed in the presence of CaCl2 (2–10 mM), (CSM–Blg–Ca), and NaCl (10–100 mM) (CSM–Blg–Na). Our results on steady-flow and oscillatory measurements indicated that shear thinning properties can be fitted well by the Herschel–Bulkley model and by the formation of highly interconnected gel structures in the complexes, respectively. Analyzing the rheological and structural features simultaneously led to an understanding that formations of extra junctions and the rearrangement of the particles in the CSM–Blg–Ca could enhance elasticity and viscosity, as compared with the effect of CSM–Blg complex without salts. NaCl reduced the viscosity and dynamic rheological properties and intrinsic viscosity through the salt screening effect and dissociation of structure. Moreover, the compatibility and homogeneity of complexes were approved by dynamic rheometry based on the Cole–Cole plot supported by intrinsic viscosity and molecular parameters such as stiffness. The results outlined the importance of rheological properties as criteria for investigations that determine the strength of interaction while facilitating the fabrication of new structures in salt-containing foods that incorporate protein–polysaccharide complexes.

Abstract Polyphenols are the most important phytochemicals in our diets and have received great attention due to their broad benefits for human health by suppressing oxidative stress and playing a protective role in preventing different pathologies such as cardiovascular disease, cancer, diabetes, and obesity. The stability of polyphenols depends on their environments of processing and storage, such as pH and temperature. A wide range of technologies has been developed to stabilize polyphenols during processing. This review will provide an overview of the stability of polyphenols in relation to their structure, the factors impacting the stability of polyphenols, the new products deriving from unstable polyphenols, and the effect of a series of technologies for the stabilization of polyphenols, such as chemical modification, nanotechnology, lyophilization, encapsulation, cold plasma treatment, polyphenol–protein interaction, and emulsion as a means of improving stability. Finally, the effects of cooking and storage on the stability of polyphenols were discussed.

The issue of achieving controlled or targeted release of bioactive compounds with specific functional properties is a complex task that requires addressing several factors, including the type of bioactive, the nature of the delivery system, and the environmental conditions during transportation and storage. This paper deals with extensive reporting for the identification of original articles using Scopus and Google Scholar based on active packaging as a novel packaging technology that controls the release of antimicrobial agents encapsulated into carriers in the food packaging systems. For evidence-based search, the studies were extracted from 2015 to 2020 and screened using the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Following the review and screening of publications, 32 peer-reviewed articles were subjected to systematic analysis. The preliminary search indicated that the encapsulation of bioactives enhances their bioavailability and stability. From a theoretical viewpoint, mathematical models play an important role in understanding and predicting the release behavior of bioactives during transportation and storage, thus facilitating the development of new packaging material by a systematic approach. However, only a few studies could formulate parameters for mathematical models in order to achieve the specific release mechanism regulated for the quality and safety of foods. Therefore, this paper will cover all encapsulation approaches, active packaging, and mathematical modeling in the food industry into structural form and analyze the challenges faced by the complex nature of active packaging in real food systems.

Cannabidiol (CBD), one of the most promising constituents isolated from Cannabis sativa, exhibits diverse pharmacological actions. However, the applications of CBD are restricted mainly due to its poor oral bioavailability. Therefore, researchers are focusing on the development of novel strategies for the effective delivery of CBD with improved oral bioavailability. In this context, researchers have designed nanocarriers to overcome limitations associated with CBD. The CBD-loaded nanocarriers assist in improving the therapeutic efficacy, targetability, and controlled biodistribution of CBD with negligible toxicity for treating various disease conditions. In this review, we have summarized and discussed various molecular targets, targeting mechanisms and types of nanocarrier-based delivery systems associated with CBD for the effective management of various disease conditions. This strategic information will help researchers in the establishment of novel nanotechnology interventions for targeting CBD.

Thermal processing of the key lime juice leads to the inactivation of pectin methylesterase (PME) and the degradation of ascorbic acid (AA). These changes affect directly the cloud stability and color of the juice. In this study, an artificial neural network (ANN) model was applied for designing and developing an intelligent system for prediction of the thermal processing effects on the physicochemical properties of key lime juice during conventional and infrared (IR) heating. The inputs of this network were time and temperature and the outputs were changes in PME activity, AA content, browning index (BI) and also cloud stability of the juice.The feed-forward neural network with a logarithmic transfer function, Levenberg–Marquardt training algorithm and eight neurons in the hidden layer (topology 2-8-4) was chosen as the best ANN model (R2> 0.95, RMSE=0.47 and SE=0.28). The predicted values using the optimal ANN model vs. experimental values represented a correlation coefficient higher than 0.95 and 0.90 during IR and conventional thermal processing, respectively. This model can therefore be applied in prediction of the effects of thermal processing on the physicochemical properties of the lime juice in pilot plants, processing factories and online monitoring.

In this work, a four-factor five-level full factorial central composite design (CCD) was used to optimize the ultrasound-assisted extraction (UAE) of saffron major components, namely picrocrocin, safranal and crocin. The process parameters included ethanol concentration (0–100%), extraction time (2–10 min), duty cycle (0.2–1.0) and ultrasonic amplitude (20–100%). The extracted compounds were measured both by spectrophotometry and chromatography techniques. The results revealed that the middle concentrations of ethanol and relatively long process durations along with high duty cycles and ultrasonic amplitudes had the most profound impact on the yields of the extracted bioactives. UAE was optimized using response surface methodology (RSM) and artificial bee colony (ABC); a comparison between these methods indicated their optimization power was approximately the same. According to the RSM analysis, an ethanol concentration of 58.58%, extraction time of 6.85 min, duty cycle of 0.82 and amplitude of 91.11% were the optimum extraction conditions, while the optimal conditions resulting from ABC were 53.07%, 7.32 min, 0.93 and 100% for the UAE variables respectively. Finally, HPLC analysis was carried out on the UAE optimum extract resulting from RSM. Four crocetin esters were detected in the optimal extract.

Abstract As the most abundant biopolymer on the earth, cellulose has recently gained significant attention in the development of antibacterial biomaterials. Biodegradability, renewability, strong mechanical properties, tunable aspect ratio, and low density offer tremendous possibilities for the use of cellulose in various fields. Owing to the high number of reactive groups (i.e., hydroxyl groups) on the cellulose surface, it can be readily functionalized with various functional groups, such as aldehydes, carboxylic acids, and amines, leading to diverse properties. In addition, the ease of surface modification of cellulose expands the range of compounds which can be grafted onto its structure, such as proteins, polymers, metal nanoparticles, and antibiotics. There are many studies in which cellulose nano-/microfibrils and nanocrystals are used as a support for antibacterial agents. However, little is known about the relationship between cellulose chemical surface modification and its antibacterial activity or biocompatibility. In this study, we have summarized various techniques for surface modifications of cellulose nanostructures and its derivatives along with their antibacterial and biocompatibility behavior to develop non-leaching and durable antibacterial materials. Despite the high effectiveness of surface-modified cellulosic antibacterial materials, more studies on their mechanism of action, the relationship between their properties and their effectivity, and more in vivo studies are required.

Orange peel oil (OPO) is one of the most common flavorings used in the food industry, but it is volatile under environmental conditions (the presence of light, oxygen, humidity, and high temperatures). Encapsulation by biopolymer nanocomposites is a suitable and novel strategy to improve the bioavailability and stability of OPO and its controlled release. In this study, we investigated the release profile of OPO from freeze-dried optimized nanocomposite powders as a function of pH (3, 7, 11) and temperature (30, 60, and 90 °C), and within a simulated salivary system. Finally, its release kinetics modelling was performed using experimental models. The encapsulation efficiency of OPO within the powders, along with the morphology and size of the particles, were also evaluated by an atomic force microscopy (AFM) analysis. The results showed that the encapsulation efficiency was in the range of 70–88%, and the nanoscale size of the particles was confirmed by AFM. The release profile showed that the lowest and the highest release rates were observed at the temperatures of 30 and 90 °C and in the pH values of 3 and 11, respectively, for all three samples. The Higuchi model provided the best model fitting of the experimental data for the OPO release of all the samples. In general, the OPO encapsulates prepared in this study showed promising characteristics for food flavoring applications. These results suggest that the encapsulation of OPO may be useful for controlling its flavor release under different conditions and during cooking.

Chitosan nanoparticles (CSNPs) can be widely used in the food, pharmaceutical, and cosmetic sectors due to their high performance, unique properties, and high surface area. In this research, CSNPs were produced by the ionic gelation method and using sodium tripolyphosphate (STPP) as an appropriate technique compared to the conventional methods. To evaluate the effects of various factors on the size, zeta potential (ZP), and optimal synthesis conditions, different concentrations of CS (1, 3, and 5 mg/mL), STPP (0.5, 0.75, and 1 mg/mL), and CS to STPP ratio (1:1, 3:1, and 5:1) were applied and optimized using the response surface methodology. The size of CSNPs was increased by using higher concentrations of CS, STPP, and CS/STPP ratios. The value of ZP was determined positive and it increased with increasing CS concentrations and CS/STPP ratios. ATR-FTIR spectra revealed interactions between CS and STPP. The DSC thermogram of CSNPs showed a double sharp endothermic peak at about 74.5 °C (ΔH = 122.00 J/g); further, the TGA thermograms indicated the total weight loss of STPP, CS, and CSNPs as nearly 3.30%, 63.60%, and 52.00%, respectively. The XRD data also revealed a greater chain alignment in the CSNPs. Optimized, the CSNPs can be used as promising carriers for bioactive compounds where they also act as efficient stabilizers in Pickering emulsions.

In this study, whey protein concentrate (WPC) was sonicated or partially hydrolyzed by Alcalase, then examined as an emulsifier and carrier for the emulsification and spray drying of grape seed oil (GSO)-in-water emulsions. The modification treatments increased the free amino acid content and antioxidant activity (against DPPH and ABTS free radicals), as well as, the solubility, emulsifying, and foaming activities of WPC. The modified WPC-stabilized emulsions had smaller, more homogeneous droplets and a higher zeta potential as compared to intact WPC. The corresponding spray-dried powders also showed improved encapsulation efficiency, oxidative stability, reconstitution ability, flowability, solubility, and hygroscopicity. The morphology of particles obtained from the primary WPC (matrix type, irregular with surface pores) and modified WPC (reservoir type, wrinkled with surface indentations), as well as the oxidative stability of the GSO were influenced by the functional characteristics and antioxidant activity of the carriers. Changes in the secondary structures and amide regions of WPC, as well as the embedding of GSO in its matrix, were deduced from FTIR spectra after modifications. Partial enzymolysis had better results than ultrasonication; hence, the WPC hydrolysates are recommended as emulsifiers, carriers, and antioxidants for the delivery and protection of bioactive compounds.

The addition of prebiotics to bread is one of the most important ways to improve its techno-functional properties. In this study, the effects of resistant starch, polydextrose, and inulin on wheat flour, dough, and bread properties were investigated. The farinography results showed that resistant starch significantly increased the development time (2:18) via a boosting effect; however, polydextrose (1:48) and inulin (1:36) weakened the dough (p < 0.05). Inulin, polydextrose, and resistant starch had the greatest effect on reducing water absorption (40, 43.2, and 48.9), respectively, (p < 0.05). According to extensography data, the addition of inulin produced the best result in baking compared to other polysaccharides. In terms of baked breads, the samples containing resistant starch had high moisture content that could be due to starch gelatinization and moisture-retention, which delays the staling process of the bread. Inulin, polydextrose, and resistant starch prebiotic ingredients affected the rheological properties of the dough, overall bread quality and organoleptic characteristics; however, resistant starch was the best prebiotic used in this study.

The development of biopolymer-based green packaging films has gained remarkable attention in recent years. In this study, curcumin active films were prepared using different proportions of gelatin (GE) and a soluble fraction of tragacanth gum (SFTG) (1GE:1SFTG and 2GE:1SFTG) by complex coacervation. The various ratios of used biopolymers did not significantly impact the mechanical properties, thickness, and WVP of final films. However, biopolymers’ ratio impacted the moisture content, water solubility, swelling ratio, and release rate. Blending curcumin with biopolymers caused a reduction in tensile strength (from 1.74 MPa to 0.62 MPa for film containing 1GE:1SFTG and from 1.77 MPa to 0.17 MPa for film containing 2GE:1SFTG) and proliferation in elongation at break (from 81.48% to 122.00% for film containing 1GE:1SFTG and from 98.87% to 109.58% MPa for film containing 2GE:1SFTG). Moisture content and water solubility of films experienced a decrease after the addition of curcumin. Antioxidant activity of curcumin-loaded films was almost five times higher than neat film samples. Furthermore, the interreaction between the carboxylic group of SFTG and amide I of GE formed an amide linkage and was proven by FTIR analysis. TGA showed a drop in the thermal stability of film samples compared to the main ingredients. In general, the complex coacervate of SFTG and GE has the advantage of developing eco-friendly and low-cost packaging film in the food industry, especially for the protection of fatty foods.

Vitamin B12 (VB12) is one of the essential vitamins for the body, which is sensitive to light, heat, oxidizing agents, and acidic and alkaline substances. Therefore, the encapsulation of VB12 can be one of the ways to protect it against processing and environmental conditions in food. In this work, the influence of pectin concentration (0.5–1% w/v), whey protein concentrate (WPC) level (4–8% w/v) and pH (3–9) on some properties of VB12-loaded pectin–WPC complex carriers was investigated by response surface methodology (RSM). The findings showed that under optimum conditions (1:6.47, pectin:WPC and pH = 6.6), the encapsulation efficiency (EE), stability, viscosity, particle size and solubility of complex carriers were 80.71%, 85.38%, 39.58 mPa·s, 7.07 µm and 65.86%, respectively. Additionally, the formation of complex coacervate was confirmed by Fourier-transform infrared (FTIR) spectroscopy and atomic force microscopy (AFM). In addition, it was revealed that the most important factor in VB12 encapsulation was pH; at a pH < isoelectric point of WPC (pH = 3), in comparison with higher pH values (6 and 9), a stronger complex was formed between pectin and WPC, which led to an increase in EE, lightness parameter, particle size and water activity, as well as a decrease in the zeta-potential and porosity of complex carriers.

Environmentally intense and negative consequences relateing to conventional meat production systems have induced some actors to suggest alternative meat sources. Diseases carried by animals, human perception of cruelty to animals, and public health concerns about cardiovascular diseases have provided the basis for the development of cultured meat. The current market is influenced by many factors, including regulators, affordability, religion, and media perception. The existing cultured meat market is also regulated by legislatures, affordability, consumer religion, and the media. Consumer perception is distributed across various aspects, including ethical priorities, nutritional profile of the meat consumed, age-based acceptance, gender differentiation, political orientation, land-based attitude, education status, socioeconomic factors, and familiarity factor with the existing product in the market. Inhibiting barriers reported among consumers—including low naturalness, safety, nutritional concerns, trust, neophobia, economic, and ethical approaches—should be employed as marketing tactics directly to address their respective concerns. Tissue culture, starter cells, printing, and 3D printing are some of the methods currently being used for the production of cultured meat. Similarly, many hybrid technologies are also being used to produce meat-like products to increase consumer familiarity along and market presence. Existing research frameworks have improved the previous mindset of consumers with media coverage, educational frameworks, and the textural attributes of cultured meat. Additional benefits of CUME may include being environmentally friendly with less production of greenhouse gases. However, consumer trust, affordability, improving nutritional status, and widescale adoption are just a few of the parameters that need to be addressed to enhance consumer acceptability of these products. The aim of this article was to analyze the current state of cultured meat and the marketing content challenges and strategies used to advance public acceptance of cultured meat.

Omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) are nominated to minimize the risk of lifestyle-related diseases. This study aimed to establish a strategy for ω-3 targeted delivery to enrich broiler meat, using ultrasound-assisted preparation of nanoemulsions. In vitro results indicated that stabilized nanoemulsions tend to have a controlled release behavior in simulated gastrointestinal fluids. Regarding the in vivo study, flaxseed oil-loaded nanoemulsions improved the growth performance, lipid profile, and oxidative stability. A greater ω-3 incorporation along with a greater content of its derivatives and a favorably lower ω-6/ω-3 were detected in the broiler meat fed with nanoemulsions containing flaxseed oil. A remarkable up-regulation was detected in the expression of long chain fatty acid desaturases and elongases by nanoencapsulated flaxseed oil. In short, this study revealed that flaxseed oil-loaded nanoemulsions have the potential for targeted delivery and to enrich broiler meat with ω-3 fatty acids.
