“…In comparison to co-suppression and antisense technologies, RNAi represents a breakthrough in efficiency that is based on transgenic expression of an inverted repeat or hairpin structure of target genes, akin to the combination of co-suppression and antisense configurations within a single transgene cassette. The simultaneous attenuation of FatB and FAD2 expression by RNAi in a low-ALA mutant led to the development of Monsanto's Vistive Gold soybean oil (Wilkes & Bringe 2015). RNAi has also been used to generate HO oils from several other oilseed crops, such as cottonseed (Liu et al 2002), flaxseed (Chen et al 2015), camelina (Camelina sativa) (Lee et al 2021, Nguyen et al 2013, crambe (Li et al 2016), and canola (Lee et al 2016).…”

In contrast to traditional breeding, which relies on the identification of mutants, metabolic engineering provides a new platform to modify the oil composition in oil crops for improved nutrition. By altering endogenous genes involved in the biosynthesis pathways, it is possible to modify edible plant oils to increase the content of desired components or reduce the content of undesirable components. However, introduction of novel nutritional components such as omega-3 long-chain polyunsaturated fatty acids needs transgenic expression of novel genes in crops. Despite formidable challenges, significant progress in engineering nutritionally improved edible plant oils has recently been achieved, with some commercial products now on the market.

Consumer preferences, labeling mandates, and dietary health concerns are driving changes to ingredient selection within the food industry. Many conventional oilseeds are being selected or genetically modified to improve the seed oil fatty acid composition ranging from raising/lowering saturates or unsaturates to incorporating new fatty acids abundant in other species. Most of these new oils have significant improvements over their commodity oil counterparts. This article reviews the most common and commercially viable new oilseed varieties providing trait‐modified oils developed within the last 10–15 years.

Antarctic krill are rich sources of functional ingredients, including astaxanthin, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). In this work, the functional ingredients are extracted by an improved aqueous enzymatic extraction method, where exogenous enzymes are not consumed and soybean oil is chosen as co‐solvent. The optimal conditions for oil recovery are determined to be a water addition of 30%, an initial pH of 7.5, a temperature of 43.2 °C, an autolysis time of 6 h, and a soybean oil addition ratio (g/g) of 3. Meanwhile, the oil recovery rate is 76.7%. The recovered oil contains 44.24 mg kg−1 astaxanthin and its total fatty acids contain 1.1% EPA and 0.6% DHA. The moisture and volatile matter content, acid value, and peroxide value of recovered oil are sufficient to meet the first grade requirements of soybean oil. The oxidative stability of recovered oil is close to that of soybean oil at room temperature. The recovered oil can be taken as a good source of EPA, DHA, and astaxanthin for consideration of use as an edible oil item for human consumption. Practical Applications: Antarctic krill (Euphasia superba) are generally known as huge biomass resources, strong endogenous enzymes, and rich sources of functional ingredients including EPA, DHA, and astaxanthin. In this work, the strong endogenous enzymes are employed to extract the functional ingredients from E. superba using soybean oil as co‐solvent. Furthermore, chemical compositions, physicochemical properties, and oxidative stabilities of the recovered oil are investigated. The results are useful for the extensive utilization of E. superba in food industry. The functional ingredients including EPA, DHA, and astaxanthin in krill are extracted by an improved aqueous enzymatic extraction method, where exogenous enzymes are not consumed and soybean oil is chosen as co‐solvent. The recovered oil can be taken as a good source of EPA, DHA, and astaxanthin for consideration of use as an edible oil item for human consumption.
