Cottonseed oil is a cooking oil extracted from the seeds of cotton plants of various species, mainly ''Gossypium hirsutum'' and ''Gossypium herbaceum'', that are grown for cotton fiber, animal feed, and oil.〔http://cotton.tamu.edu/cottoncountry.htm〕 Cotton seed has a similar structure to other oilseeds such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability.〔(【引用サイトリンク】title=Twenty Facts About Cottonseed Oil )〕 ==Composition== Its fatty acid profile generally consists of 70% unsaturated fatty acids (18% monounsaturated, and 52% polyunsaturated), 26% saturated fatty acids.〔(【引用サイトリンク】title= Nutrient data for 04502, Oil, cottonseed, salad or cooking )〕 When it is fully hydrogenated, its profile is 94% saturated fat and 2% unsaturated fatty acids (1.5% monounsaturated, and 0.5% polyunsaturated).〔(【引用サイトリンク】title= Nutrient data for 04702, Oil, industrial, cottonseed, fully hydrogenated )〕 According to the cottonseed oil industry, cottonseed oil does not need to be hydrogenated as much as other polyunsaturated oils to achieve similar results.〔 Gossypol is a toxic, yellow, polyphenolic compound produced by cotton and other members of the order Malvaceae, such as okra. This naturally occurring coloured compound is found in tiny glands in the seed, leaf, stem, tap root bark, and root of the cotton plant. The adaptive function of the compound facilitates natural insect resistance. The three key steps of refining, bleaching and deodorization in producing finished oil act to eliminate the gossypol level. Ferric chloride is often used to decolorize cotton seed oil.〔(【引用サイトリンク】title= Research abstract: Southern Regional Research Laboratory )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cottonseed oil」の詳細全文を読む スポンサード リンク
