In this study, the influence of fermentation and different drying techniques on the bioactive components, antioxidant activity, phenolic components, fatty acids, nutrients and sensory characteristics of fresh and processed jalapeño peppers was investigated. At the end of the fermentation, the pH, acidity and salt values of the brine were determined as 3.38, 0.09% and 6.02 g/100 mL, respectively. The oil results of pepper samples were found between 2.0% (microwave and air) and 2.60% (oven). Total carotenoid and total phenolic amounts of fresh (control) and processed peppers (air, conventional, microwave and fermentation) were characterized to be between 3.38 (fermented) and 65.68 µg/g (air) to 45.81 (fermented) and 350.69 mg GAE/100 g (microwave), respectively. Total flavonoid quantities of fresh and processed pepper samples were defined to be between 14.17 (fresh) and 482.74 mg/100 g (microwave). 3,4-dihydroxybenzoic acid and catechin amounts in fresh and processed jalapeño peppers were defined to be between 0.43 (fermented) and 11.0 mg/100 g (microwave) to 1.36 (fermented) and 44.87 mg/100 g (microwave), respectively. The predominant fatty acids of pepper oils were palmitic, oleic and linoleic acid. The oleic acid amounts of fresh and processed jalapeño pepper oils were specified to be between 9.52% (air drying) and 29.77% (fermented), while the linoleic acid values of pepper oils vary between 10.84% (fermented) and 68.38% (air drying). The major elements of fresh and processed peppers were K, P, S, Ca, Mg, Fe and Zn in decreasing order. Protein amounts in fresh and processed jalapeño peppers were characterized to be between 8.59 (fermented) and 12.22% (oven). As a result of panelist evaluations, the most appreciated features (4.83 score) were the flavor, color and texture feature. [ABSTRACT FROM AUTHOR]

In this study, the effects of microwave (540, 720 and 900 W) and oven (120, 150 and 230°C) roasting techniques on the total phenolics, flavonoids, antioxidant capacity, polyphenolic and fatty acid results of sunflower seed and oils were investigated. Total phenol (except oven 150°C), flavonoid (except oven 120°C) contents and antioxidant activity values of sunflower seeds and oils subjected to oven and microwave heat treatment decreased compared to the control. Total phenolic, total flavonoids and antioxidant activities were higher in MRS oil than ORS oil. Individual phenolic constituent in both seed and oil samples from ORS and MRS showed significant (p < 0.05) changes to the control (non‐roasted seed and its oil). A general increase in the phenolic components of seeds and oils was observed with oven and microwave roasting compared to the control. Oleic acid values (%) of the oil extracted from seeds roasted in oven and microwave systems were recorded to be between 23.76 (120°C) and 29.41% (150°C) to 24.32 (540 W) and 26.10% (720 W), respectively. Linoleic acid values of the oils obtained from seeds roasted in oven and microwave systems varied to be between 57.01 (150°C) and 65.89% (120°C) to 60.70 (720 W) and 65.26% (540 W), respectively. As a result of the applied heat treatment, while the linoleic acid values of the oil samples decreased, an increase was observed in the palmitic, stearic and oleic acid values of the oil.

Summary: In this study, the effect of roasting, boiling and germination processes on bioactive compounds, antioxidant activity, fatty acid and phenolic profiles and biogenic elements of quinoa seed and oils was assigned. The moisture amounts of boiled and germinated quinoa seeds were recorded to be significantly higher than the control. Also, the oil yield of quinoa seeds decreased compared with the control by roasting, boiling and germinating. The total phenolic and flavonoid quantities of quinoa seeds were assigned to be between 137.70 (germinated) and 315.00 (boiled) to 156.62 (boiled) and 402.38 mg/100 g (control), respectively. Antioxidant capacities of processed quinoa seeds were reported to be between 11.91 (germinated) and 14.43 mmol kg−1 (roasted). The highest total flavonoid and antioxidant capacities were recorded in the control group and roasted quinoa seeds. The highest decrease in total phenol amount of quinoa seeds was detected in germinated quinoa. Gallic acid and catechin values of quinoa seeds varied to be between 29.17 (boiled) and 38.00 mg/100 g (control) to 2.72 (germinated) and 137.26 mg/100 g (control), respectively. The rutin, ferulic acid and p‐coumaric acid contents of the processed (roasted, boiled and germinated) quinoa seeds gradually increased compared with the control. The highest palmitic, oleic, behenic and arachidonic acids were recorded in germinated quinoa oil, followed by the fatty acids of boiled, raw (control) and roasted quinoa seed oils in descending order. P and K amounts of quinoa were established to be between 2203.44 (roasted) and 3314.59 (control) to 4350.60 (boiled) and 6266.85 mg kg−1 (control), respectively. [ABSTRACT FROM AUTHOR]

BACKGROUND: Factors such as variety, genetics, soil structure and plant diseases affect the oil amount and properties of flaxseed. By applying heat and various extraction treatments to flaxseed, the storage ability of the seed is increased by the removal of moisture, and the stability of phytochemicals in the seed against heat can be determined. RESULTS: Total carotenoid and phenol of flaxseeds changed from 0.13 (control) and 0.61 mg g−1 (120 °C) to 202.64 (control and 90 °C) and 225.69 mg 100 g−1 (120 °C), respectively. While total flavonoid of flaxseed roasted at different temperatures varied between 636.0 (90 °C) and 786.00 mg 100 g−1 (120 °C), antioxidant activity values for raw and roasted flaxseeds between 59.32% (control) and 68.64% (120 °C) were recorded. Oil content of seeds changed between 34.07 and 42.57% (P < 0.05). Viscosity of flaxseed oil extracted using different systems was between 31.95 (cold‐pressed; control) and 36.00 mPa s (ultrasonic; 120 °C). The dominant phenolics of flaxseeds were identified as isorhamnetin, resveratrol, quercetin, catechin, apigenin‐7‐glucoside and campherol. The oils of flaxseeds contained 55.27–58.23 linolenic, 17.40–18.91 oleic, 14.03–14.84 linoleic and 4.97–5.37 palmitic acids, depending on extraction method and roasting temperature. CONCLUSION: Roasting and oil extraction methods did not have a significant effect on free acidity, but was found to affect peroxide value. The predominant phenolic constituents of flaxseed samples were isorhamnetin, resveratrol, quercetin, catechin, apigenin‐7‐glucoside and campherol, respectively. The major fatty acids of flaxseed oil were determined as linolenic, oleic, linoleic and palmitic. © 2023 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

- Abstract
Background and objectives: Teff grains are subjected to several treatments, such as cooking and baking, and studies on the impact of thermal treatments such as roasting on the bioactive properties, phenolic compounds, fatty acids, and minerals of teff grains are scarce. The objective of this study was to evaluate the effect of microwave and oven roasting processes on total phenol, antioxidant activity, fatty acid compositions, and phenolic compounds of teff grains. Findings: Roasting treatments greatly influenced the biochemical content and bioactive properties of teff grains. Roasting increased oil, carotenoids, total flavonoids, and antioxidant activity of teff grains with the highest values being observed in microwave‐roasted grains, except total flavonoids of soluble fraction which was highest in oven‐roasted grains. It also increased total phenolic of soluble fraction and most phenolic compounds in both soluble and bound fractions with the highest values being found in conventional oven‐roasted grains, except gallic acid, trans‐cinnamic acid, naringenin, and isorhamnetin which were high in control samples. In addition, oven roasting increased palmitic acid, linoleic acid, nickel, and boron, whereas microwave roasting increased the content of stearic acid, calcium, magnesium, sodium, iron, copper, zinc, and lead of teff grains compared to controls. Conclusions: The findings of this study indicate that teff grains are suitable sources of nutrients and bioactive compounds that could be enhanced by roasting. Significance and novelty: The teff grains have high nutritional value, antioxidants, fatty acids, and phenolic compounds which are improved by roasting treatment and hence probable potential application in functional foods. Studying the effects of processing treatments such as roasting of teff grain will help in promoting the worldwide utilization of this important gluten‐free cereal. [ABSTRACT FROM AUTHOR]

The oil content of both 'raw' and hazelnut kernels was significantly (p < 0.05) reduced as the microwave power increased from 180 W to 360 W. The contents of fatty acids flucuated for all varieties with microwave power, with a significant (p < 0.05) increment observed for 'Sivri' hazelnut at 180 and 720 W. The maximum linoleic acid contents for 'Raw', 'Sivri' and 'Tombul' hazelnuts were found as 11.87%, 12.61% and 17.68% for nuts roasted at 540 W, unroasted and those roasted at 720 W, respectively. It was observed that K (9735.1 mg/kg) and Mg (2343.7 mg/kg) contents of the investigated samples were found at the maximum levels in unroasted 'Tombul' hazelnut, while the highest P (2845.0 mg/kg) and S (1795.3 mg/ kg) contents are determined for hazelnut roasted at 720 W (p < 0.05). The highest Ca content in hazelnut kernel was also observed at 360 W with 2400.9 mg/kg. However, roasting process did not dramatically affect the mineral contents of samples. [ABSTRACT FROM AUTHOR]

A study was carried out to evaluate oil contents, fatty acid composition and tocopherol contents of several walnut types in relation to roasting process. The major fatty acid identified was linoleic acid in both roasted and unroasted walnut oils. Linoleic acid contents of unroasted walnut oil varied from 46.44 (Type 9) and 63.59% (Type 7), while the linoleic acid contents of roasted walnut oils at 120°C/h ranged from 55.95% (Type 3) to 64.86% (Type 10). Interestingly, linolenic acid contents of both roasted and unroasted oils changed between 9.43 (Type 10) and 16.29% (Type 8) to 9.64 (Type 10) and 16.58% (Type 8), respectively and were significant (p < 0.05) different. γ-tocopherol content of unroasted walnut oils varied between 6.3 (Type 3) and 11.4 mg/100g (Type 1) and γ-tocopherol contents of roasted walnut oils ranged between 28.1 (Type 8) and 38.2 mg/100g (Type 3). The oil could be useful for industrial applications owing to good physicochemical properties. Fatty acid values for oil obtained from roasted walnut were slightly higher than those reported for unroasted walnut oils. [ABSTRACT FROM AUTHOR]

Some physicochemical properties of the oil, crude protein, sugars, and amino acids of the leaves and seed meals of two Moringa species were determined and compared using Student's T-test. The oil properties and fatty acid composition were significantly (at either p ≤ .01 or p ≤ .05) varied between the two species. The sterols and tocopherols contents of the species oil differed significantly. Most of the sterols were not detected in Moringa oleifera oil. The sugars contents were significantly different between the two species. The protein contents of M. oleifera leaves and seed meals were significantly higher than those of Moringa peregrina. Compared with M. peregrina, the M. oleifera leaves and seed meals had significantly higher amounts of amino acids. The most concentrated amino acids in the M. oleifera leaves and seed meals were glutamic acid, aspartic acid and leucine whereas those in M. peregrina were threonine, serine, and proline. Practical applications Moringa seed kernels contain a significant amount of oil. Moringa leaves are a good human food and animal feed. Various parts of Moringa oleifera are incorporated into the traditional food of humans. The leaves of Moringa are a good source of protein, vitamin A, B, and C. The leaf of M. oleifera contains crude protein up to 25%. In many tropical and subtropical countries, various parts of M. oleifera (leaves, fruits, immature pods, and flowers) are incorporated into the traditional food of humans. [ABSTRACT FROM AUTHOR]

Matthäus, Bertrand and Özcan, Mehmet Musa
- Abstract
The oil yields of hazelnut kernels collected from Germany (Münster) and Turkey range from 8.1 to 64.1%. The main fatty acids in hazelnut kernel oils are oleic (76.3-82.6%), linoleic (6.5-14.0%), and palmitic (5.7-6.5%). The hazelnut kernel oils contained an appreciable amount of α-tocopherol (19.9-63.9 mg/100 g), with a mean value of 40.02 mg/kg, and γ-tocopherol (1.3-15.5 mg/100 g), with a mean value of 4.84. α-Tocopherol was the predominant tocopherol in all hazelnut kernels. The major sterols were β-sitosterol, ranging from 78.13 to 82.56 mg/kg; campesterol, ranging from 4.79 to 7.42 mg/kg; and δ5-avanasterol, ranging from 1.26 to 5.24 mg/kg. The highest minerals were K and P followed by Ca, Mg, Na, and Zn. P contents of all samples were established between 2029.90 and 4376.66 ppm. The results may also be useful for the evaluation of nutritional information. As a result, the present study showed that the kernels of hazelnut are a potential source of valuable oil which might be used for food and non-food applications. In addition, hazelnut kernel oil has a high nutritive value and can be recommended for processing of healthy food products. [ABSTRACT FROM AUTHOR]

Abstract: Studies were carried out on the oil content, fatty acids, tocopherols and sterols in the seeds of two carobs (Ceratonia siliqua), cultivated and wild, from Turkey. The oil yields of cultivated and wild carob seeds were established as 1.73 and 1.82% on a dry weight basis, respectively. The main fatty acids in cultivated and wild carob seed oils are linoleic (49.1% and 51.0%), oleic (30.4% and 26.5%), palmitic (10.3% and 12.0%) and stearic (3.5% and 4.6%), respectively. Tocopherols and phytosterols are important constituents of the unsaponifiable fraction of several seed oils. The major tocopherol in both seed oils was γ-tocopherol. The composition (mg/100g) was as follows α-tocopherol (69.06 and 70.39mg/100g), P8 (22.29 and 24.78mg/100g), δ-tocopherol (8.70 and 10.66mg/100g), β-tocopherol (2.30 and 1.85mg/100g). The total tocopherol contents had 208.45 and 223.14mg/100g, respectively. The total content of sterols of both oils were determined as 16400.94 and 30191.55mg/kg, with β-sitosterol as the predominant sterol that accounted for more than 70% of the total amount of sterols other sterols, campesterol (5.33–5.32%), stigmasterol (0.58–11.43%) 7-avenasterol (3.45–3.03%), 7-stigmasterol (2.16–2.4%), and chlerosterol (1.33–1.0%) were detected in both carob oils. As a result, the accurate quantification of these analyses has very important applications for the nutrition sciences. [Copyright &y& Elsevier]

Olea europea L. fruits were evaluated for weight, moisture, ash, crude protein, crude oil, energy, crude fibre, roundness, resistance against extra force and product density. The relative density, refractive index, free fatty acids, peroxide value, iodine value and unsaponifiables were determined in the olive oils. The main fatty acids identified by gas chromatography were palmitic acid (16:0), palmitoleic acid (16:1), stearic acid (18:0), oleic acid (18:1) and linoleic acid (18:2). Of the identified fatty acids, lauric acid (12:0), linolenic acid (18:3), arachidic acid (20:0), eicosenoic acid (20:1), behenic acid (22:0) and lignoseric acid (24:0) were found in trace amounts. As expected, the oleic acid content was the major fatty acid of olive oil. Oleic acid was represented in much higher concentrations than the other acids. The product roundness, resistance against extra force, product density and weight of 100 fruit were established as technological characteristics in olive fruit. The damage energy and the unit of volume deformation energy of the Memecik and Tavsanyureği varieties were 1.36×10-3 J and 3.59×10-4 J/mm3 and 1.89×10-3 J and 5.10×10-4 J/mm3, respectively. The fruits showed a similar composition, and both fruit and oil contained unsaturated fatty acids. [ABSTRACT FROM AUTHOR]

• Tigernut is commonly known as earth almond. • Tigernut is rich in oil, and total and individual phenolics. • Tigernut flour with wheat improved the bioactive compounds, and fatty acids of cookies. • Tigernut/wheat cookies had a comparable organoleptic quality to wheat flour cookies. • Tigernut/wheat cookies are functional products rich in bioactive compounds. This study aimed to evaluate cookies made with wheat (0%, 80%, 60%, and 50%) and tigernut flour (0%, 20%, 40%, and 50%) from two different sources. Standard methods were applied to determine the chemical properties, phenolic component, fatty acid composition, mineral content, and sensory properties of cookies. Tigernut flour from both sources was rich in oil, and total and individual phenolics, but with low antioxidant activity compared to wheat flour. The addition of tigernut flour to wheat resulted in increase of the content of bioactive compounds, minerals, and fatty acid contents of cookies. The cookies produced by formulating wheat with tigernut had a comparable organoleptic quality scores to wheat flour cookies. The production of cookies with both wheat and tigernut flour showed that this mixture is an interesting opportunity to have a functional product rich in bioactive compounds and considered satisfactory by consumers.

Some pre-treatments such as blanching, freezing, and blanching-freezing were applied to potato slices before frying while the untreated samples were used as a control. The frying process was carried out in sunflower and olive oils. The percentage oil uptake in slices varied from 4.26% to 10.35% when fried in sunflower oil. In the case of the control samples slices fried in olive oil contained high monounsaturated fatty acid (oleic acid) content (5.45%), and lesser oil uptake was observed than those processed in sunflower oil, which is rich in polyunsaturated fatty acid (linoleic acid is 5.99%) (p < 0.05). The oil uptake was also compared in the case of potato slices fried in two different oils after pre-treatments. The maximum oil uptake was observed in the case of blanched-frozen potatoes, whereas minimum oil uptake was observed in frozen only slices for both oils. The fatty acid contents in oils extracted from fried potato slices showed that the predominant fatty acids were palmitic, stearic, oleic, and linoleic acids.

Bu çalışmada, Ankara ve ilçelerinden toplanan 10 farklı kavun çeşidinden (Yuva (Mühürlü), Çikolata, Hacı Bekir, 10 dilim, Sarı Kışlık, Kara Kışlık, Portakal, Kırkağaç-Dalaman, Kırkağaç-Altınbaş, Çankırı Kışlığı) elde edilen çekirdek ve çekirdek yağlarının bazı fizikokimyasal özellikleri analiz edilerek, çekirdeklerin besinsel değerleri ve çekirdek yağlarının kalitesi araştırılmıştır. Çekirdeklerin nem, ham kül, ham protein, ham selüloz, mineral içeriği, ham yağ verimi, toplam fenol ve toplam flavonoid içeriği; çekirdek yağlarının yağ asidi kompozisyonu, tokoferol ve sterol içerikleri belirlenmiştir. Ham yağ içeriği en yüksek çeşidin Altınbaş olduğu (%33.00) ve kavun çekirdeği yağlarının yüksek düzeyde linoleik asit içerdiği saptanmıştır. Çekirdek yağlarında temel yağ asitleri linoleik, oleik ve palmitik asit olarak tespit edilmiştir. Kavun çekirdeği yağları %57.14-74.66 linoleik, %12.95-28.37 oleik ve %6.98-10.07 palmitik asit içermiştir. En yüksek linoleik asit içeriği Çankırı Kışlığı çekirdek yağında tespit edilmiştir. Yağ örneklerinin α-tokoferol değerleri ise 1.81(Kırkağaç)-10.44 (Çankırı Kışlığı) mg/kg, γ-tokoferol 6.55 (Mühürlü)-29.29 mg/kg (Çankırı Kışlığı) arasında değişmiştir. Bunun yanı sıra kavun çekirdeklerinin toplam fenol içerikleri 615 (Portakal)-850 mg GAE/kg (Sarı Kışlık) arasında değişmiştir. Kavun çekirdeğinin hem yağ içeriğinin hem de esansiyellik gösteren linoleik asit içeriğinin yüksek olması bu yağın gıda endüstrisinde yemeklik yağ olarak kullanılabileceğinin bir göstergesidir., In this study, physicochemical properties of seeds and seed oils of 10 different melon types (Slot (sealed), Chocolate, Hacı Bekir, 10 slices, Yellow Winter, Black Winter, Orange, Kırkağaç- Dalaman, Kırkağaç- Altınbaş, Çankırı winter) which collected from Ankara and around were analyzed and investigated the nutritional values of seeds, quality of seed oils. Moisture, crude ash, crude protein, crude fiber, mineral content, oil yield, total phenolic and total flavonoid content of melon seeds; fatty acid composition, tocopherol and sterol content of seed oils were determined. The highest crude oil proportion (19.44-33.00 %) was found for Altınbaş and the highest level of fatty acid in melon seed oils was found as linoleic acid. The main fatty acids of the oils were linoleic, oleic and palmitic acids. Generally, the oils contained 57.14-74.66% of linoleic acid, 12.95-28.37% of oleic acid and 6.98-10.07% of palmitic acids. The highest linoleic acid content was found in Çankırı Kışlığı seed oil. α-Tocopherol contents varied between 1.81(Kırkağaç)-10.44 (Çankırı Kışlığı) mg/kg forthe oil samples. Besides, total phenolic content of the oils were found between 615 (Portakal)-850 mg GAE/kg (Sarı Kışlık). The melon seed is higher in terms of oil content and linoleic acid content. So this oil can be used as an edible oil in the food industry., Bu tez çalışması BAP tarafından 15201048 nolu proje ile desteklenmiştir.

WOS: 000487761700023, PubMed: 31454759, In the study, the impact of harvest time on total phenolic content, antioxidant activity, and phenolic compounds of prickly pear (Opuntia ficus-barbarica A. Berger) fruit pulp and the oil content and fatty acids profile of the seed were investigated. The highest total phenolic content was determined as 156.77 mg/100 g in July 1 harvest, while the maximum antioxidant activity and total oil content were found as 9.81% and 6.80% at the last stage of maturation (15 August), respectively. The highest oleic (28.51%), palmitic (22.61%) and stearic acid contents (9.20%) in seed oil were observed in June 15 harvest. The highest value for linoleic acid (57.50%) was detected in August 15 harvest. Prickly pear is a vital source of bioactive constituents such as phenolic and antioxidant substances in terms of being useful for human health and the optimum harvesting time to retain high quantities of most phenolic compounds is 1st July., Deanship of Scientific Research at King Saud UniversityDeanship of Scientific Research at King Saud University [RG-1439-016], The authors extend their appreciation to the Deanship of Scientific Research at King Saud University for funding this work through researchgroup no.

WOS: 000471288600017, The oil contents of seeds were between 4.92% (Ferulago aucheri) and 16.47% (Ferula parva). The highest oleic acid contents were detected in Ferulago syraea (67.15%), Ferulago pauciradiata (67.15%), Ferulago pachyloba (68.82%), Ferulago syriaca (66.16%), Prangos uechtritzii (60.37%), Ferula tingitana (77.26%), and Ferula szowitsiana (58.81%) seed oils. Oleic acid contents of Ferulago spp. (except F. aucheri) oils were found higher than those of other plant seed oils used in experiment (except F. tingitana). The behenic acid content (75.38%) of F. aucheri were significantly higher than other samples. The K contents of plants ranged between 2,888.41mg/kg (F. aucheri Boiss.) and 21,601.26mg/kg (Ferula lycia Boiss.); Ca contents of plants ranged between 5,041.86 (Marrubium catariifolium Desr.) and 39,858.36mg/kg (F. tingitana L.). In addition, the P contents of plants remained between 299.25 (M. catariifolium Desr.) and 4,674.64mg/kg (Marrubium trachyticum Boiss.). The protein contents of plant seeds ranged between 1.75 (F. aucheri Boiss.) and 5.40% (M. trachyticum Boiss.). Practical applicationsPlant seed oils have been used for centuries by rural communities in foods, medicines, cosmetics, and fuel. They have been observed to carry excellent nutritional, nutraceutical, and pharmaceutical values. They are provided with good quantities of different nutrients and important fatty acids. The study will help to understand the differences in fatty acid and mineral composition of different plants from Apiaceae and Lamiaceae families., King Saud UniversityDeanship of Scientific Research at King Saud University [RG-1439-016], King Saud University, Grant/Award Number: RG-1439-016
