Included are phenolic compounds and their derivatized products. Thermochemical conversion, especially pyrolysis, offers one of the strongest opportunities for producing advanced biofuels and phenols. Previous work showed that various unsaturated fatty acids (soybean, brown grease, safflower [SF]) can react with phenol across the fatty acid double bond(s) via the branched-chain fatty acid (BCFA) synthesis. Although phenolic BCFAs offer a gateway toward bio-based antimicrobial coatings, the phenolic component has remained dependent on fossil-derived phenol. We have closed this gap by incorporating refined biophenolics fraction from pyrolysis in the BCFA synthesis. Pyrolysis-derived phenols are incorporated in the synthesis, thus making the biophenolic BCFA fully biorenewable. Catalytic fast pyrolysis of switchgrass produced bio-oils with sufficiently high concentrations of phenol and cresols (biophenolics). These one-ring biophenolics were extracted and redistilled, yielding a fraction of &gt;75 wt% phenols. SF and pennycress (PC) oils were hydrolyzed and subsequently functionalized with biophenolics using a ferrierite zeolite catalyst. Excess biophenolics were removed using molecular distillation. Yields of biophenolic BCFAs ranged from 63% to 76%.

Four groups of goat kids (six kids in each group) of 6–7 months were fed different diets for 120 days: a basal diet (Group A), a basal diet with vitamins and inorganic minerals (Group B), a basal diet with vitamins and organic minerals (Group C), and a basal diet with vitamins and nano minerals (Group D). Growth parameters, carcass, meat qualities, and expression of genes relevant to growth, metabolism, antioxidant activity, and myogenesis were assessed. Significant differences (<i>p</i> &lt; 0.05) were observed among the groups in growth and carcass quality.

Meat, including from goat, rich in unsaturated and polyunsaturated fatty acids, omega fatty acids, Fe, Zn, Se, and vitamins A and E, can help address nutritional deficits and wellbeing, thus having a greater consumer preference and market potential. The present research showed that the supplementation of vitamins and organic and nano trace elements increased their contents in meat, besides improvements in animal growth, muscle mass, and fatty acid profile. Higher costs of organic and nano-minerals may be a limiting factor for their application in goat production. However, this could be countered by upscaling their production, better absorption, bioactivities, animal growth performance, desirable meat quality and healthier nutrient profile, lower dose rate, and eco-friendly nature. The upregulation of the studied genes indicates interaction between supplemented micronutrients and genes, besides highlighting the possible mode of action. Thus, this approach could be very promising in the production of meat with an improved fatty acid profile and rich in trace elements and vitamins.</p>\u0000 </div>","PeriodicalId":11988,"journal":{"name":"European Journal of Lipid Science and Technology","volume":"127 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is still difficult to come up with an efficient deacidification method that makes use of high-acid-value oil to produce edible goods that are both high-quality and value-added. The present work provides a newly developed, adaptable, and long-lasting ion exchange deacidification method. Three different ion exchange resins, that is, Amberlite IRA 400 (AMT), Amberlyst A₂₆ (A₂₆), and Dowex WGR-2 (DOX) at different concentrations were assessed to remove free fatty acids (FFAs) by adsorption using a column, where AMT (85.92%) and A₂₆ (98.02%) showed a good result compared to DOX (75.4%). To further confirm the reduction in the acid value of the treated oil, multiple methods were used, including FFA measurement by titration, gas chromatography (GC), high-performance liquid chromatography (HPLC), and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR). All these methods consistently demonstrated a reduction in FFA levels in the oil collected after treatment with resin. Additionally, to assess the effect of the resin on the oil, various physicochemical parameters were analyzed. It was found that most of the tocopherols and tocotrienols were preserved, and there was little to no impact on other key quality parameters.</p>\u0000 <p><i>Practical Applications</i>: Our study offers valuable insights into the development of a deacidification technology for removing FFAs from oil using resins.

Traditionally, fish oil (FO) has served as the primary lipid source in commercial fish feed. However, due to the dwindling availability and escalating costs of FO, the sustainable growth of aquaculture has been hindered. On the other hand, vegetable oil (VO) has emerged as a promising alternative lipid source for fish diets, owing to its abundance, cost-effectiveness, and rich content of essential C18 fatty acids. While numerous studies have explored the impact of VO on fish growth and health, it has been noted that most VO cannot entirely replace FO in the diet due to its adverse effects. Hence, current research suggests that innovative strategies such as genetic modification, nutritional programming, and supplementation with functional compounds may help alleviate the negative effects associated with dietary VO. Given the critical need to seek alternative lipid sources in fish feed to address the limited global supply of FO, coupled with the cost-effectiveness and nutrient content of VO, it is imperative to further investigate their application in fish feed formulations to support sustainable fish production.</p>\u0000 <p><i>Practical Applications</i>: This review highlights the importance of finding alternative lipid sources for fish feed in order to support sustainable aquaculture growth.
