REFINING OF COTTONSEED OIL OBTAINED BY EXTRACTION METHOD

Abstract

Technological methods of refinement of raw cottonseed oil show that the quality and nutritional benefits of refined oil mainly depend on the content of free fatty acids, phospholipids, gossypol and its derivatives, as well as other substances. The reduction and complete removal of certain oil-related substances can significantly improve the performance of the final product. Refining the raw oil and ensuring high features of product also depend on the nature of the feedstock and the production methods for cottonseed oil. Today, the alkaline method of purifying vegetable oils and their by-products is widely used in the production of edible oils. However, the refining of cottonseed oil using an alkaline sodium hydroxide solution, as the author of the article states, is associated with high consumption of sodium hydroxide, a relatively low yield of refined oil, significant losses and consumption of energy resources.
