Soybean oil contains only trace amounts of fatty carboxylic acids (about 0.3% by mass in the crude oil, 0.03% in the refined oil). [7] Instead it contains esters. In the following content, the expressions "fatty acids" and "acid" below refer to esters rather than carboxylic acids.
These days, "seed oil" is more of a pejorative term than a technical definition, referring to oils high in omega-6 fatty acid, including: Canola. Corn. Soybean. Cottonseed. Grapeseed. Sunflower ...
Soybean has been genetically modified to improve the quality of soy oil. Soy oil has a fatty acid profile that makes it susceptible to oxidation, which makes it rancid, which limits its usefulness in the food industry. [20]: 1030 Genetic modifications increased the amount of oleic acid and stearic acid and decreased the amount of linolenic acid.
The soybean, soy bean, or soya bean (Glycine max) [3] is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses. Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh.
The American Heart Association recommends getting 5% to 10% of daily calories from omega-6 fatty acids. For a 2,000-calorie diet, this equals 11 to 22 grams per day and between 100-200 calories.
Diglyceride, in this example with a saturated fatty acid residue (highlighted blue) and an unsaturated fatty acid residue (highlighted green). Mono- and diglycerides of fatty acids ( E 471 ) refers to a naturally occurring class of food additive composed of diglycerides and monoglycerides used as an emulsifier in foods such as infant formula ...
Castor oil has numerous industrial uses, owing to the presence of a hydroxyl group on the fatty acid. Castor oil is a precursor to Nylon 11 . Castor oil may also be reacted with epichlorohydrin to make a glycidyl ether which is used as a diluent and flexibilizer with epoxy resins.
For instance, α-linolenic acid is an 18:3 fatty acid and its three double bonds are located at positions Δ 9, Δ 12, and Δ 15. This notation can be ambiguous, as some different fatty acids can have the same C:D numbers. Consequently, when ambiguity exists this notation is usually paired with either a Δ x or n−x term. [13]
