MODERN RESEARCH IN THE FIELD OF OBTAINING FOOD INGREDIENTS FROM SECONDARY APPLE PROCESSING RESOURCES

Secondary apple processing resources – apple pomace formed during the production of direct-squeezed juice, serve as a valuable source of a complex of antioxidants such as phenolic compounds, contain dietary fiber, including pectin, cellulose and hemicelluloses, B vitamins, macro and trace elements. The article overviews modern research in the field of obtaining food ingredients from the secondary resources of apple processing.So, apple pomace has been studied by many researchers as a promising source of biologically active phenolic compounds, which are used in the food, pharmaceutical and cosmetic industries due to their high antioxidant and antimicrobial activity. Apple pomace is used as raw material for pectins due to the widespread use of pectin in the food industry (production of marshmallows, marmalade, confiture, jams, sausages, juices, yogurts, bakery products and other products), medicine and pharmaceuticals (production of baby granules, suspensions, gels, for imparting viscosity to emulsions, binding of heavy metal ions, healing of wounds, development of nutrient media), the cosmetics industry (production of certain types of face masks and gels).As a result of bioconversion of apple pomace, a number of edible organic acids of the L form can be obtained: acetic, citric and lactic acids. A review of modern foreign studies in the field of obtaining food ingredients from apple pomace showed the promise of their use as a valuable raw material, as well as the relevance and need for the development of domestic highly effective innovative technologies for the production of phenolic compounds, pectin and food organic acids to solve the problems of import substitution
