However, given the uncertainty in the correlations between flavor attributes and volatile compounds, assessing the flavor quality of commercial peanut oil retail products (PORPs) based on updated analysis techniques remains challenging. In this study, 21 commercial samples were collected for investigating this correlation. From the sensory evaluations, the 16 fragrant PORPs show differences esp. for the roasted (4.25–10), the sweet (0–4.25), and the steamed (0–4.25) attributes while the roasted attribute is dominant for all the products. For volatile profile analysis with updated analytical technology, the fragrant PORPs also show significant difference in terms of volatile profiles and intensities. The total intensity can differ from 16.37 to 66.59 mg/kg. Multivariate statistical methods (MSMs) revealed the significant correlations between volatile compounds and specific sensory attributes. Notably, 1‐hexanol and phenylethyl alcohol demonstrate a strong correlation with the raw peanut flavor attribute. Benzeneacetaldehyde (BA) exhibited a positive correlation with sweet flavor. dl‐Pantolactone has a positive effect on roasted flavor. Hexanal and 3‐octen‐2‐one are highly related to off‐flavor notes. In addition, based on machine learning (ML), three groups of volatile compounds were found to be highly correlated with specific flavor attributes. Notably, a cluster comprising seven compounds, namely 2‐ethenyl‐6‐methylpyrazine, 2‐methyl‐6‐[(E)‐1‐propenyl]pyrazine, benzaldehyde, BA, nonanal, dl‐pantolactone, and 2‐acetopyridine exhibiting a positive correlation with roasted, steamed, and sweet flavor attributes. Furthermore, recombination experiments were conducted to verify the synergistic effect of these seven compounds on flavor performance and agreements were reached.","PeriodicalId":501405,"journal":{"name":"The Journal of the American Oil Chemists’ Society","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, esterification is employed to convert FFAs into fatty acid methyl ester (FAME). Herein, the effectiveness of tungstosilicic acid hydrate (TSAH) as an unsupported heteropoly acid (HPA) catalyst for FFA esterification in ACPO was investigated. The FFA content was reduced from 8.43% to 0.95% under optimum conditions (4 wt% catalyst dosage, a methanol to oil molar ratio of 10:1, 150 min and a temperature of 60°C). Noteworthy, the TSAH catalyst showed stability over 7 cycles. The kinetic analysis revealed that the FFA esterification process closely followed pseudo first‐order kinetics, with an R2 value of 0.94. Furthermore, the biodiesel produced from TSAH‐treated ACPO meets the standard specifications outlined by ASTM D6751 and EN 14214. This research highlights the effectiveness of TSAH in catalyzing FFA esterification without the need for additional support materials or modifications.","PeriodicalId":501405,"journal":{"name":"The Journal of the American Oil Chemists’ Society","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the fatty acid biosynthetic pathway, the fatty acid desaturase 2 (FAD2) enzyme converts OA to LA. Safflower is reported to have 12–20 FAD2 genes. Gene expression analysis of four FAD2 genes during seed development in a high LA variety, PBNS‐12, revealed high expression of FAD2‐1 at 21 days after flowering (DAF), correlating with high LA accumulation. Fatty acid profiling of 448 Indian safflower germplasm accessions revealed four lines to have high (58%–77%) OA content, with NASF‐39 having the highest OA content. Interestingly, all four high OA lines showed the same mutation in the FAD2‐1 gene. The DNA sequence of FAD2‐1 from the four high OA lines showed a deletion of C at the +606 position, resulting in a premature stop codon at the +733 position and a truncated protein of 244 amino acids. Hence, despite the high expression levels of FAD2‐1 in NASF‐39 at 18–21 DAF, it exhibited high OA (77%). The dysfunctional nature of the truncated FAD2‐1 in NASF‐39 was evident in molecular docking studies with 1‐stearoyl‐2‐oleoyl phosphatidylcholine. We also sequenced FATB, a thioesterase responsible for releasing stearic acid from acyl carrier protein for further desaturation to oleic acid, where an A773G substitution was observed. This resulted in E258G substitution in NASF‐39 FATB compared to that of PBNS‐12. This probably made the acyl‐binding pocket of NASF‐39 FATB unstable, contributing to high OA accumulation. Thus, the outcomes of this study can help develop super and ultra‐high oleic safflower varieties through various genetics and genomics approaches.","PeriodicalId":501405,"journal":{"name":"The Journal of the American Oil Chemists’ Society","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimum extraction process, which includes 8 min of ultrasonication followed by a 2‐h acid hydrolysis, released new phenolics (e.g., catechin, myricetin, etc.) and increased the total phenolic content (TPC) from 586.24 ± 11.45 to 982.42 ± 6.61 μmol gallic acid equivalent (GAE)/L, and 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical inhibition from 46.63 ± 1.39 to 60.87 ± 1.12%. Acid hydrolysis increased the cupric chelating activity of the extracts while decreasing ferrous chelating activity and trans‐ferulic acid concentration significantly (p < 0.05). The acid‐hydrolyzed extract at a TPC of 100 μmol GAE/L prolonged the lag phase of hexanal accumulation in the emulsion from 0 to 8 days, while 400 μmol GAE/L TPC of unhydrolyzed extract increased the lag phase to 12 days.

For this, hydroxytyrosol, rosmarinic acid and their lipophilic counterparts, (hydroxytyrosyl dodecanoate esters or eicosyl rosmarinate esters) were loaded into these carrier vesicles and the antioxidant efficiencies of these formulations were compared with those of the corresponding antioxidants alone. Using the conjugated autoxidizable triene assay (CAT assay), our results shows that loaded synthetic liposome mimicking the lipid membrane composition of olive extracellular vesicle allowed to enhance the antioxidant effect of the loaded antioxidant especially with the two lipophilic hydroxytyrosol and rosmarinic acid esters. On the contrary, the loading of the studied antioxidant into the olive extracellular vesicles did not result in an improvement of the antioxidant activity. The antioxidant effects of loaded vesicles were also evaluated in rapeseed oil (1% w/w)‐in‐water emulsions that were stored at 40°C for 21 days and for which oxidative status was monitored by the quantification of primary and secondary oxidation compounds. In that case, the boosting effect of liposomal carriers was not confirmed. This could be due to a different type of emulsions compared to the one used with the CAT assay as different surfactants and oxidation inducers were employed. Additionally, the limited physical stability of the carrier could be involved as liposomes loaded with the most lipophilic antioxidants, namely hydroxytyrosyl dodecanoate and eicosyl rosmarinate were shown to be instable for period exceeding 10 days of storage.","PeriodicalId":501405,"journal":{"name":"The Journal of the American Oil Chemists’ Society","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research focused on seed yield, oil content, and oil yield, considering variations in growing degree days (GDD) at different growth stages. In both years, seed yield was significantly affected by lack of rainfall. In 2021, safflower genotypes had an average seed yield of 1540 kg ha−1, while in 2022, it increased to 2390 kg ha−1 due to higher rainfall during critical growth stages. Different genotypes showed different performances in seed yield each year, highlighting the importance of selecting drought‐tolerant genotypes for breeding programmes. Oil content also showed significant variations between genotypes and years. Drought stress during flowering and seed filling periods generally led to a decrease in safflower oil content. However, in 2021, despite drought during the seedling stage, there was an increase in average oil content, possibly due to compensatory mechanisms related to reduced seed yield and dry matter content. In addition, the study looked at GDD values at different growth stages and found considerable variation among genotypes in GDD accumulation. Genotypes with higher GDD accumulation tended to have higher seed and oil yields, indicating better stress tolerance. Conversely, early maturing genotypes with lower GDD levels were better suited for regions with lower average temperatures. The results highlight the importance of considering both rainfall and temperature factors when selecting safflower genotypes for specific regions. In conclusion, the study highlights the impact of seasonal climate change on safflower productivity and the need to develop new safflower varieties capable of adapting to the predicted hotter and drier conditions due to climate change.","PeriodicalId":501405,"journal":{"name":"The Journal of the American Oil Chemists’ Society","volume":"212 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
