cotton seed oil

In the United States, the number of cottonseed oil used as cooking and salad oil is less than that of soybean oil, but many of the characteristics of cottonseed oil, especially the oxidation stability, are still very good. Stearic component isolated from cottonseed oil iodine value in winter is about 72,. Cottonseed oil can also be used as vegetable shortening and frying medium, in the manufacture of frozen confections in cottonseed oil can be used instead of cream. Gossypol gossypol (gossyp01) is a yellow phenolic hydroxyl naphthalene aldehyde compounds, mainly exist in the root, stem and seed of the Malvaceae from cotton, cottonseed kernel content is the highest. Gossypol is divided type, aldehyde enol, quinone 3 tautomers. Chemical character is very active, very easy to oxidation metamorphism. According to the existing form of gossypol into free gossypol (FG) and the combination of gossypol (BG). With the combination of free gossypol and gossypol from cottonseed protein, phospholipids, in sugars by chemical and, less toxic.

Preventive measures: gossypol poisoning must be carried out after detoxification treatment before consumption of cottonseed oil. By diatomite and alumina of gossypol in cottonseed oil adsorption; or thermal processing removal; or by the alkali smelting method is refined to poison. Secondly, improved varieties, breeding of Low Gossypol Content of cottonseed.
