Lipases of TLL, AOL, RML and CALB were evaluated. Results indicated that TLL exhibited better acidolysis performance and decanoic acid content from 30% to 45% could be obtained; while other lipases (CALB, RML, and AOL) showed poor performance. In addition, macroporous resins of DA-201, ADS-17, D3520, and mesoporous silicas of SBA-15, Al-MCM-41, HMS, were suitable for TLL immobilization. TLL@SBA-15 was selected for acidolysis and the reaction conditions were optimized through single factors study and orthogonal design. The optimum conditions for the acidolysis were: lipase amount 6 wt%, decanoic acid: camellia oil molar ratio 14:1, reaction time 12 h and temperature 50°C.

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. These results were compared to those obtained from the analysis of a solvent-extracted oil. 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. Raffia oil's use in food products as a replacement for palm oil would thus allow to diversify edible oil sources, stimulate the local economy, and promote healthier and more sustainable diets.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 5","pages":"843-854"},"PeriodicalIF":1.9,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aocs.12932","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914704","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}

In the present study, various extraction methods including biomass pretreatment through ultrasonication and conventional lipid extraction techniques such as Bligh & Dyer and Soxhlet were employed for lipid extraction from Kappaphycus alvarezii. Among these methods, pretreatment of ultrasonication combined with solvent extraction (PT + SE) resulted in highest extraction yield of 21.5% ± 0.38%, surpassing the yield achieved by the Bligh-Dyer method (PT + BD) and the control method, which yielded 19.42% ± 0.1% and 10.7% ± 0.15%, respectively. PT + SE oil possesses lower values in molecular weight, viscosity, and density when compared to PT + BD oil. The trans-esterified samples of PT + BD (T1) and PT + SE (T2) respectively demonstrated greater efficiency in converting methyl esters, with T2 achieving a conversion rate of 92% ± 0.21%, while T1 achieved 84.15% ± 0.15%. It was observed that T2 had a high scavenging rate of 86.42% ± 0.22% indicating its significant ability to neutralize free radicals. In contrast, T1 exhibited a slightly lower scavenging rate of 69.56% ± 0.1%, when compared to T2. T2 sample demonstrated remarkable proteinase inhibition of 79.16% ± 0.18, comparable to salicylic acid, indicating the presence of potent anti-inflammatory salicylic acid analogues in the algal oil.

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}

Among the nuts, peanuts are composed of approximately 50% oil, which is abundant in unsaturated fatty acids, tocopherols, and phytosterols. This study investigated the changes in phytochemical profile, antioxidant capacity, and oxidative stability of oil from germinated peanuts. Peanuts were germinated over 0, 2, 4, 6, and 8 days. 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. These results highlight that germination of peanut seeds is an effective strategy for enhancing peanut oil's phytochemical content and oxidative stability, thereby presenting potential benefits for health-conscious consumers.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 4","pages":"785-791"},"PeriodicalIF":1.9,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749484","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}

Although synthesis of GA has been extensively studied to evaluate the role of various catalysts and effect of reaction conditions, statistical modeling and optimization of the synthesis process has not been reported. In the present work, the optimization of the synthesis of GA using a mixture of lauryl and myristyl alcohol was carried out with the aid of response surface methodology (RSM) considering the conversion of the reaction, PP and KV at 40 and 100°C as dependent variables. The optimal reaction conditions were temperature, pressure, and time of 220°C, 300 mbar, and 10 hours respectively. The optimum conversion was 99.14%, including dimer yield of 81.76%, PP of −3°C, KV at 40 and 100°C of 34.12 and 7.22 cSt, respectively. The results obtained by the RSM were then authenticated, applying artificial neural networks (ANN) generated with the help of MATLAB. The ability of the generated model to predict the response variables was validated by less than 5% error for almost all the models, confirming their statistical significance. Also, the tribological potential for linear Ginol-12,14 (FA) and synthesized branched GA as lubricant additive was evaluated by determining its physiochemical, thermal and tribological properties.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 4","pages":"771-783"},"PeriodicalIF":1.9,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749953","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}

In this context, both chemical (CIE) and enzymatic (EIE) interesterification techniques can be used. However, it has been found that CIE technology may produce process-related by-products known as dialkyl-ketones (DAK). The current study aims at investigating the formation of DAK during IE. Therefore, five edible oils and fats were selected based on their potential use in IE: Elaeis Guineensis palm stearin (POSt), high oleic palm stearin (HOPSt), palm kernel stearin (PKSt), high oleic sunflower oil (HOSO) and high oleic palm oil (HOPO). The investigated blends were divided into HOPO-based blends (POSt:HOPO 50:50, PKSt:HOPO 50:50, HOPSt:HOPO 50:50 and 30:70 wt:wt%) and HOSO-based blends (POSt:HOSO 30:70, 50:50 and 70:30 wt:wt%). They were all subjected to both CIE (using sodium methoxide) and EIE (using TLIM lipase as catalyst); analyses of physical properties and determination of DAK content were performed before and after IE. This study demonstrates that DAK were not formed during the EIE process regardless of the investigated matrix, whereas they were produced during CIE, and that they require sufficient rearrangement of triglycerides (TAG) to be formed. It has also been shown that unsaturated fatty acids are more prone to form DAK regardless of the fat matrix. However, there is no linear relationship between the amount of DAK and the amount of unsaturated fat in the matrix.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 4","pages":"753-763"},"PeriodicalIF":1.9,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749402","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}

In addition, the antioxidant activity of PE-g-FA was evaluated according to the DPPH and ABTS free radical scavenging ability. Olive oil in water emulsions, containing emulsifiers WPI and PE-g-FA, were assessed for their physical and oxidative stability through particle size, zeta-potential, peroxide value (POV), and 2-thiobarbituric acid reactive substance (TBARS) formation. The results indicated that the formation of covalent bonds between the pectin carboxymethyl groups and FA hydroxyl group. The determination of the total phenolic content showed that PE-g-FA contained seven times more polyphenols than native PE. DPPH and ABTS free radical scavenging rate of 0.5HMP-g-FA were increased by 56.83% and 18.90% compared with HMP, respectively. In addition, the emulsion stabilized by WPI and 0.5HMP-g-FA showed smallest and uniform average particle size (855.9 ± 51.13 nm) on the 1st day.
