Quality indicators of extracts and sublimates in the form of powders obtained with waste-free technology for processing vegetables and fruits

As a result of the implementation of scientific research, innovative technologies have been systematized for creating consumer products of increased nutritional and biological value, as well as preventive and dietary products based on expanding and improving the raw material base of agricultural products. The purpose of the research is to develop scientific directions for the creation of innovative technologies for the production of sublimated and extracted plant products from organic raw materials, including wild plants, as a source of biologically active substances, as well as complex universal food additives; substantiation of the ingredient composition of the developed products, assessment of their quality, safety, harmlessness and economic efficiency. Technologies for obtaining powders by extraction and sublimation methods have been developed. Nutrients were extracted with alcohol, then the mixture was pasteurized at 50-55°C, the dense part was separated, thickened, then dried, packaged and stored. The production of powders is carried out by the method of sublimation from the pulp, packaging and storage on the basis of non-waste processing of raw materials. From more than 50 samples of powdered extracts and sublimates, 14 variants of one-, two-, three- and four-component blends of berry powders were selected. Optimal organoleptic characteristics of sublimated and extracted products from organic vegetable (dove, raspberry, blackberry, cranberry, sea buckthorn, honeysuckle, lingonberry, sweet pepper, paprika, tomatoes, parsley, dill, basil) and wild-growing raw materials (nettle, lemon balm, thyme) were obtained in the best way. realizing a useful complex of technological and nutritional properties: the production of a new generation of powdered food intermediates (composites), optimized food mixtures of increased biological value. The vitamin composition of powdered extracts and sublimates was determined by gas-liquid chromatography, confirming their high quality.
