The objective of this study was to develop an edible coating made from sunflower protein flour and apply it to roasted sunflower seeds as a preservation procedure for this food product. Roasted sunflower seeds were prepared with and without sunflower coating and stored for 60 days at room temperature. Samples were extracted every 15 days to determine the peroxide values (PV), conjugated dienes (CD) and volatile compounds. The uncoated seeds showed the highest PV (83.7 mEqO2/kg at Day 15 and 149.2 mEqO2/kg at Day 60), while the coated seeds presented lower values (39.2 and 69.3 mEqO2/kg at 15 and 60 days, respectively). Regarding the DC values, this parameter also showed the same behavior as PV. Thirteen volatile compounds were identified in analyzed samples (by GC–MS), where hexanal, 2-octenal and nonanal showed significant variations. The uncoated sunflower seeds showed a greater release of volatile compounds. According to the correlation analysis, hexanal presented the highest correlation value between CD and PV in coated (0.76 and 0.79, respectively) and uncoated seeds (0.70 and 0.91, respectively). The obtained results suggest that, although the oxidative reactions occur in roasted sunflower seeds, the application of the coating delays this deterioration process, slows down the oxidation of lipids and contributes to prolonging the useful life of this product.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 5","pages":"885-892"},"PeriodicalIF":1.9,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting polyols were analyzed using standard analytical techniques including Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectroscopies. It was observed that the polyols obtained through the photochemical route exhibited better outcome compared with those synthesized using the thermal treatment. Additionally, we employed computational chemistry technique using density functional theory (DFT) calculation to get insights into various product yields. The DFT results revealed that the hydrogen bond network likely contributed to the improved stability, hence obtained higher product yield of the polyol MSBO-TMPAE compared with that of MSBO-GAE. Our study also focuses on applying the synthesized polyols in polyurethane rigid foams and casts. The polyurethanes prepared from these polyols have comparable thermal and mechanical properties to that of the commercially available polyurethanes.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 6","pages":"973-983"},"PeriodicalIF":1.9,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144213881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering stricter health, safety, and environmental regulations, it is crucial to advocate the transition from chlorinated solvents like chloroform and dichloromethane to sustainable alternatives. This study aimed to assess the lipid extraction efficiency of the ethyl acetate (EtOAc) method compared to the Folch method across four marine resources. The tested species were Atlantic salmon (Salmo salar Linnaeus, 1758) and three low-trophic species: the zooplankton Calanus finmarchicus (Gunnerus, 1770), the microalgae Porosira glacialis (Grunow) Jörgensen, 1905, and the macroalgae Saccharina latissima (Linnaeus). Our results indicated that the EtOAc method is as efficient as the Folch method in extracting lipids from Atlantic salmon fillets and freeze-dried C. finmarchicus (p > 0.05). However, the relative lipid yields from frozen and freeze-dried P. glacialis and S. latissima were 49.5% and 27.3%, respectively, when substituting the Folch method with the EtOAc method. Therefore, we recommend the adoption of EtOAc as a sustainable alternative for materials high in neutral lipids to avoid the underestimation of polar and complex lipids. However, the proportion of PUFAs in the extracted lipids was determined not only by the choice of solvent but also by the biological composition of the materials. We encourage future efforts to choose a suitable lipid extraction method considering the characteristics of the raw materials and their composing lipids, in addition to the trade-offs between extraction efficiency and sustainability.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 5","pages":"871-883"},"PeriodicalIF":1.9,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aocs.12935","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 2k factorial experiment was used to study the influence of the intrinsic parameters of the press (rotation speed and diameter of the output die) on the oil extraction efficiency. Screw press extraction efficiency yield was of 43.3 ± 1.7%, representing an extraction rate of 80.8 ± 6.2%. Mechanical extracted raffia oil was chemically characterized measuring acidity and peroxide values; fatty acid (FA), tocopherol, and sterol compositions, and carotenoids content.

The screw press extracted raffia oil exhibited good quality (richer in monounsaturated FA and total sterols; similar total contents in unsaturated FA, tocopherols, and carotenoids; lower acidity and peroxide values), surpassing the solvent-extracted one. Raffia oil's composition would offer a promising alternative to palm oil (obtained from the pulp of Elaeis guineensis fruit). Compared to palm oil, the press- and solvent-extracted raffia oils presented a similar content in saturated FA, ~3.3-fold less monosaturated FA, ~3.4-fold more polyunsaturated FA, 3.5-fold more linoleic acid, and between 2.4 and 2.8-fold more linolenic acid.

Nanostructured lipid carriers (NLC), as one of the lipid-based nano-delivery systems, employs a blend of solid and liquid lipids, which improves the solubility, stability, and bioavailability of bioactive substances. This study aimed to optimize the NLC containing thymoquinone-rich oil (NLC-TQO) formulation using the Box–Behnken design; assess its antioxidant activity and oxidative stability by measuring 2,2-diphenyl−1-picrylhydrazyl (DPPH) radical scavenging activity, thymoquinone (TQ), and tocopherol contents over 28-day storage; and evaluate the impact of incorporating beta-carotene as singlet oxygen quencher on the oxidative stability of the NLC-TQO. The optimized formulation involved 4.16% lipids (glyceryl monostearate and TQO), 5.85% Tween 80 as the surfactant, and 8.20 min of ultrasonication. NLC formulations demonstrated better DPPH activity retention than the emulsions, with cold and dark storage conditions being the most effective for preserving antioxidant activity. TQ stability in the NLC was observed at elevated temperatures without light, with around 50% remaining intact. However, TQ degraded rapidly under light, almost entirely by day 7. Gamma-tocopherol exhibited better stability than alpha-tocopherol, especially under light. The addition of beta-carotene enhanced NLC-TQO's oxidative stability. These findings revealed the potential of the NLC formulation as an effective delivery system for TQ with better oxidative protection compared to emulsions, making it a promising option for pharmaceutical and food industry applications.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 4","pages":"793-810"},"PeriodicalIF":1.9,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aocs.12930","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oil from germinated peanuts exhibited increased levels of α-tocopherol, phytosterols, and carotenoids, while the γ-tocopherol, oleic acid, and linoleic acid levels were reduced. Notably, the oil from germinated peanuts at Day 8 exhibited substantially improved antioxidant activity and oxidative stability compared with oil from ungerminated peanuts. These enhancements were attributed to the elevated phytochemical content of the peanut oil resulting from germination.
