Soybean oil (British English: soyabean oil) is a vegetable oil extracted from the seeds of the soybean (Glycine max). It is one of the most widely consumed cooking oils and the second most consumed vegetable oil. [2] As a drying oil, processed soybean oil is also used as a base for printing inks and oil paints.
Soybean meal, or soymeal, is the material remaining after solvent extraction of oil from soybean flakes, with a 50% soy protein content. The meal is 'toasted' (a misnomer because the heat treatment is with moist steam) and ground in a hammer mill. Ninety-seven percent of soybean meal production globally is used as livestock feed.

Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of plants. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature. [2] [3] Vegetable oils are usually edible.
Polyunsaturated vegetable oils are widely used as precursors to epoxidized oil products because they have high numbers of carbon-carbon double bonds available for epoxidation. [4] The epoxide group is more reactive than double bond, thus providing a more energetically favorable site for reaction and making the oil a good hydrochloric acid ...
Textured soy chunks. Textured or texturized vegetable protein (TVP), also known as textured soy protein (TSP), soy meat, or soya chunks, is a defatted soy flour product, a by-product of extracting soybean oil. It is often used as a meat analogue or meat extender. It is quick to cook, with a protein content comparable to some meats.
By contrast, olive oil and avocado oil are considered fruit oils. They’re often cold-pressed, which retains many of the plant-based compounds that benefit health — but also makes the oils more expensive and prone to smoking at high heat. Seed oils are composed mostly of unsaturated fatty acids, including monounsaturated and polyunsaturated fat.
Lecithin can easily be extracted chemically using solvents such as hexane, ethanol, acetone, petroleum ether or benzene; or extraction can be done mechanically. Common sources include egg yolk, [7] marine foods, soybeans, [7] milk, rapeseed, cottonseed, and sunflower oil. It has low solubility in water, but is an excellent emulsifier.
Some forms of soy are more processed than others, such as soy protein isolate or textured vegetable protein—common in protein powders and vegan meat alternatives—and soybean oil, found in many ...
