Corn, waste, corn silk, pharmacology, cosmetics


One of the problems of modern technology for processing food technology products of plant origin is the use of their waste - peel, seeds, shells  oilcake, leaves and other components, containing a significant amount of bioactive compounds (phenols, peptides, carotenoids, anthocyanins, fatty acids, enzyme, fibers etc.), which in most cases are not  utilized  and are burned, or go to dumps, worsening the environmental situation.  The production of potential drugs  for the cosmetic and medical industries from them is of great interest. A similar problem  takes place also in Georgia. A large amount of waste remains after processing the corn crop - stems, leaves, corn stigmas. In this review,that is mainly based on literature data, the problem of using corn stigmas (silk), which is available in abundance, is considered. Judging by the chemical composition, corn stigma powder contains a number of phenolic compounds, pectin, glucan, glucomannan, cellulose, hemicellulose, lignin and others. It also contains Na, Mg, K, Ca, copper, iron, manganese, zinc. Many scientists have studied   antioxidant, anti-cancer, anti-inflammatory, acute and chronic activities.  Their studies and a number of other tests have shown the pharmacological activity of extracts from the powder and their safety for use ,when they are taken in certain doses. According to available data, products, obtained from corn production waste, have found wide application in cosmetology. They are used as  absorbents, fillers, proteins, emulsifiers, surfactants. All this confirms the need of using waste products from the production of corn grain - corn stigmas (silk), for further purposes.
