Annotation

Vegetable oils contain accompanying substances and impurities of various compositions and properties that affect the quality of the finished product and further processing processes. To remove these substances, a refining process is carried out, in particular adsorption refining using activated carbon, silica gel, zeolite, etc.

This scientific article presents the results of a study on the bleaching processes of cottonseed oils and the fact that the amount of coloring substances in cottonseed oil, namely carotenoids and gossypol, is higher in oils obtained from grades III-IV. It was also found that the mass fractions of chlorophyll and bound gossypol in the oil obtained from a mixture of grades III-IV were higher than in the cottonseed oil obtained from a mixture of grades I and II.

Keywords
