Abstract

The aim of this study was to assess how the application of Limosilactobacillus fermentumBAL-21-ITTG in alginate-based edible coatings to osmodehydrated papaya pieces affects the physicochemical and organoleptic properties of the fruit. The papaya was sliced, and these pieces were osmodehydrated at 40 °C in a sucrose solution (45 °Brix) for 6 h. Subsequently, the osmodehydrated papaya pieces (OPPs) were dried for an additional 6 h at 40 °C. The OPPs were categorized into four groups and subjected to the following treatments: T1 (coated with a sodium alginate solution and L. fermentum, followed by gelation with CaCl2); T2 (coated with a sodium alginate solution and L. fermentum); T3 (coated with L. fermentum); and T4 (uncoated). Subsequently, the OPPs were stored in polyethylene containers at 4 °C for a duration of 34 days. The viability of L. fermentumand its survival during gastrointestinal simulation, as well as physicochemical, microbiological, and organoleptic properties were assessed during storage. The T1 treatment exhibited increased firmness throughout storage and sustained higher L. fermentumviability (8.88 log CFU/g) with a 98% survival rate during gastrointestinal simulation. The sodium alginate coatings, serving as a carrier for L. fermentumaddition, enhanced the organoleptic attributes of the OPPs over the 34-day storage period. Sodium alginate sourced from S. fluitansis suitable for food applications. Therefore, this technology, involving the addition of sodium alginate from S. fluitansand L. fermentum, could be employed for functional food production and industrial applications.

9. Development and characterization of alginate-based edible film from Sargassum fluitansincorporated with silver nanoparticles obtained by green synthesis

Abstract

The high susceptibility to deterioration and diseases during the supply chain and/or during the storage of fresh products is a problem in the industry, and edible films are proposed as efficient methods to preserve its quality. The objective was to obtain and characterize silver nanoparticles (AgNPs) and determine their effect on optical, barrier and mechanical properties of alginate-based films. The alginate was extracted from Sargassum fluitans. AgNPs were obtained by green synthesis using Gliricidia sepium. The UV–Vis and dynamic light scattering (DLS) were used to characterize the AgNPs. The antifungal activity of AgNPs was investigated using several fungal strains. Films were formulated by using 2 and 3% alginate, as well as 0, 1, and 2 mg of AgNPs per mL of formulation, with glycerol as a plasticizer. A randomized experimental design was used to test the effect to alginate and the AgNPs concentrations. The results were analyzed by an ANOVA test (p< 0.05). The films were characterized by water vapor permeability (WVP), mechanical properties, opacity, color, glass transition and melting temperatures, as well as scanning electron microscopy (SEM) and energy dispersive X-Ray (EDS) spectroscopy. WVP, optical and mechanical properties of the films were influenced statistically with alginate and AgNPs concentrations. The PVA values varied between 0.83 and 1.74 g mm h−1kPa−1m−2. The results demonstrated that films made with higher alginate and AgNPs concentrations exhibited higher tensile strength (20.35 MPa) and elongation at break (74.56%). The AgNPs showed percentages of growth inhibition higher than 79% in all fungal strains tested. The films formulated had attractive properties that are used to extend shelf life of foods.
