ENZYMATIC MODIFICATION OF WHEAT RICE
Abstract
The article presents conceptual approaches to solving technological and technical problems in the creation of functional foods. General approaches are proposed to change existing technologies to improve the efficiency of integrated raw material processing and to increase the production of high-quality foods and food ingredients with antioxidant properties. Cereal crops are the richest source of functional ingredients and a major component of human nutrition. It is proved that most of the nutrients are in the products of its processing. For the first time, polyphenols from cereal raw materials were obtained by biotechnological means. The feasibility of pretreatment of raw materials with amylolytic and proteolytic enzymes for purification and cleavage of polysaccharide matrix has been established. Based on the regularities of enzymatic hydrolysis of polysaccharides, we used the processing of wheat bran with multifunctional drug Viscozyme L with hemicellulase, cellulase, pectinesterase and feruloesterase activities, which resulted in a high effect of degradation of certain covalent cells, ferulic acid from 40.99 to 2507.9 mcg / g. It is determined that this method of obtaining the target components allows to preserve their native structure, especially the supramolecular structure, which determines their physiological effect. The influence of plant polyphenols on the cultivation of probiotic microorganisms is characterized. the comparative characterization of the prebiotic properties of the polyphenols obtained from wheat bran and the concentrate of the polyphenols from the grape buds "ENOANT" are substantiated. The possibility of increasing the proportion of free polyphenols by fermentation of wheat bran is shown. It is established that the extract of polyphenols from wheat bran can be used for its purpose as an effective antioxidant, which does not have a negative effect on the state of the basic physiological systems of the body.
