Oleosome oil-in-water emulsions (Фoil = 0.1) were created and stored along with the bulk oils and lecithin emulsions for 63 days at 40°C. The TAGs in oleosomes were more oxidatively stable than in the bulk oils and lecithin emulsions, as indicated by the 17-day longer lag phase and a 1.6–1.8 times slower maximal hydroperoxide formation compared to the bulk oils and lecithin emulsions. Moreover, we made the first steps towards understanding the high stability of TAGs in oleosomes by monitoring the consumption of oleosome-associated antioxidants (tocopherols and carotenoids). Using oleosome extracts could be a strategy to retard TAGs oxidation in oil-in-water emulsions.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 2","pages":"435-449"},"PeriodicalIF":1.9,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aocs.12902","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362660","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}

Our findings revealed that MF emulsions possessed a distinct advantage, with a droplet size and distribution that promoted exceptional oxidative stability, evidenced by a sustained reduction in oxidative markers and enhanced retention of bioactive components, including EPA and DHA, and the potent antioxidant astaxanthin. In contrast, HPH yielded larger and less uniform particles, correlating with diminished stability. The in vitro digestion studies underscored the superior bioaccessibility of MF emulsions, with a pronounced release of free fatty acids during the intestinal phase, indicative of an optimized digestion and absorption process due to the smaller droplet size of the emulsions. The study's insights advocate for the adoption of microfluidization in the food industry for the development of advanced delivery systems for n-3 fatty acids, particularly in the context of KO-based products. The technique shows promise in enhancing the quality, stability, and bioavailability of these products, which are rich in health-promoting lipids. The microfluidization technique emerges as a promising avenue for the fortification of a diverse range of commercial food, beverage, and pharmaceutical products with lipids that contribute to health and wellness.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"101 11","pages":"1329-1339"},"PeriodicalIF":1.9,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642315","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}

However, this could be unsafe and pose a health threat to consumers. This work investigates the thermal degradation of edible coconut oil under prolonged heating using chemometrics analysis of proton nuclear magnetic resonance (1H NMR) data. Coconut oil samples were heated continuously without food matrix at three different temperatures (150, 175, and 200°C) for 12 h and the 1H NMR spectra were collected every hour. NMR data revealed the formation of aldehyde oxidation products. Partial least squares discriminant analysis (PLS-DA) discriminated the samples based on temperature and heating time. The Variable Importance Projection revealed the discriminating peaks highlighting the spectral feature due to hydroperoxides and aldehydes in the oil degradation. A probe into the 1H NMR of the degradation products of saturated coconut oil confirmed the formation of a ketone as evidenced by a CH2 triplet in the chemical shift region of protons alpha to a ketone. The results showed that the thermal degradation of coconut oil was influenced by temperature, time, moisture, and oxygen in the air which can contribute to the advancement in the control and assessment of coconut oil quality.","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 2","pages":"425-434"},"PeriodicalIF":1.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362911","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}

These properties are dependent on their structures; therefore, the tailored production of targeted MELs is required to obtain the desired properties. Over the past two decades, the genomes of MEL producers have been analyzed, revealing the MELs synthesis pathway and related genes. Using this information, it has become possible to tailor-produce MELs by modifying the synthesis pathway. Furthermore, in recent years, novel chemical synthesis methods for MELs have been developed, enabling precise control over the fatty acid chain lengths of chemically synthesized MELs.

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.

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.

Therefore, this study's objectives were to extract crawfish oil (CO) from UC and determine the impact of temperature and heating duration on CO's thermal stability and flow properties. However, extracting oil from these undersized specimens could potentially add value to the crawfish industry. Crawfish minced meat (CMM) was obtained by passing cooked and chilled UC through a pilot scale deboning machine. CO was extracted by agitating CMM at 70°C for 30 min, followed by centrifugation at 10,000×g. CO was analyzed for inherent physicochemical characteristics, heating time (0–8 h), temperature (45–85°C) effects on peroxide value (PV) and astaxanthin (ASX) content, and flow properties at 5–35°C. ASX content, PV, water activity, bulk density, specific gravity, and free fatty acid values in CO were found to be 1.52 ± 0.06 mg/g oil, 0.22 ± 0.07 meq/kg, 0.56 ± 0.02, 0.88 ± 0.00, 0.90 ± 0.00 g/mL, and 0.11 ± 0.04%, respectively. ASX content in CO showed no significant change within or between same-temperature and different-temperature heated samples after 8 h. PV increased significantly from 0 to 8 h of heating at all tested temperatures (45, 65, and 85°C; Δ = 0.31, 0.51, and 10.76 meq/kg, respectively). CO had pseudoplastic characteristics below 30°C and Newtonian flow from 30 to 35°C. The Arrhenius equation suitably described the relationship between temperature and apparent viscosity of CO.

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":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 2","pages":"351-363"},"PeriodicalIF":1.9,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209587","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}
