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.

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.</p>","PeriodicalId":17182,"journal":{"name":"Journal of the American Oil Chemists Society","volume":"102 2","pages":"295-304"},"PeriodicalIF":1.9,"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":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Desirability approach was utilized to optimize oleogels formulations based on rheological parameters of yield stress and gel-to-sol transition temperature of conventional solid fats (hydrogenated fat, butter, and margarine). Fat-tailored oleogels were also characterized by their texture, thermal behavior, and microstructure. The concentration of CLW (0.75–4.0 wt%), but not of α-tocopherol (0.5–10 wt%), affected the rheological behavior of oleogels. Yield stress and the gel-to-sol transition increased, respectively, from 2.00 to 200.8 Pa and from 40.2 to 64.8°C as the CLW concentration increased. α-Tocopherol can be added to improve the nutritional value of CLW-based oleogels without affecting their rheological fingerprint. The optimum formulations to mimic the rheological fingerprint of butter, margarine, and hydrogenated fat comprised CLW between 2.12 and 2.51 wt%, showing desirability values of 0.58, 0.76, and 0.73, respectively. Increasing the CLW contents increased the crystal number (4194 ± 381 to 7646 ± 544) and hardness (6.45 ± 0.30 to 10.4 ± 0.36 N) of fat-tailored oleogels, besides accelerating crystallization. Therefore, it was possible to tailor oleogels structured with low CLW concentration (&lt;2.5 wt%) loaded with α-tocopherol to fairly replicate the rheological properties of margarine and hydrogenated fat.

The oleogel was tested as a potential alternative to traditional deep-fat frying with sunflower oil for frying doughnuts. The different frying times of oleogel were examined to assess the physical properties of the oleogel. Afterward, a comparative analysis was conducted between doughnuts fried in sunflower oil and oleogel. The results showed that doughnuts fried in oleogel absorbed approximately 37.8% less oil than those fried in sunflower oil.

Nine M₄ mutants, along with their parents, were grown in two contrasting environments (Taoujdate and Afourare) to investigate their seed oil, phenolic and flavonoid contents, the balance between omega-6, omega-9, and omega-3 fatty acids, iodine value, and susceptibility to oxidation.
