In recent years, the problem of deficiency of biologically active substances in a number of food products has arisen. This is due to a deterioration in the quality of seed and planting material and, accordingly, a decrease in the content of BAS in the cultivated fruit and vegetable raw materials. In this regard, processing companies are forced to fill the lack of vitamins and dyes with synthetic components. The aim of the research is to obtain concentrated food additives from domestic plant raw materials. To achieve this goal, the tasks of obtaining powders from fruits and berries are solved with maximum preservation of BAS of the raw material during drying. High-quality powders from fruits and berries are obtained by cryogenic technology, using liquid nitrogen at one or several stages of the process. As intermediate results of the research, the paper presents materials on the dispersion composition of cryopowders and the solubility of their various fractions in aqueous media. The technology of obtaining and using powdered food additives from fruits and berries, ground in liquid nitrogen, has been approved. The comparative characteristics of the composition cryopowders from apricot, sea-buckthorn, pumpkin, feijoa and persimmon are given. The results of the studies confirmed the expediency of using cryopowders from fruits and berries to enrich various food products
The market for functional food products is continuously
increasing and, according to analysts, by 2020 its
share will reach 40% of all food products. The development
of the healthy food has been gathering momentum
in recent years, the search for non-traditional
types of raw materials is constantly being conducted,
and new recipes for products enriched with natural
food additives are being created. In this regard, special
attention is paid to the production and use of powdered
food additives from plant raw materials. Theoretical
significance and practical applicability of powder
technologies in different years was substantiated by
such famous scientists as Deryagin B.V., Donchenko
L.V., Zimon A.D., Zubchenko A.V., Kasyanov G.I.,
Magomedov G.О., Paschenko L.P., Rebinder P.A.,
Tilesnik M.A., Yankhin E.D. In their opinion, using
natural food additives, it is possible to obtain functional
food products with specified chemical composition
and properties. The objects of our research were apricot,
grape seeds, pumpkin flesh, black currant and seabuckthorn
berries, spinach, apples and flour from lowfat
barley. In the course of the study, the effect of dispersity
of the obtained powders on their antioxidant
activity and frictional properties was studied. The expediency
of introducing powders into the composition
of multicomponent food products for enriching them
with carbohydrates, vitamins and microelements is
shown. The organoleptic evaluation of the produced
powders showed that they have high taste values. The
study of organoleptic and microbiological indices of
products enriched with such powders indicates prolongation
of their shelf life. As the main results of the study, we note the assessment of the chemical composition
of the powders from the investigated objects, as
well as the improvement of the technology of drying of
plant raw materials with sparing technological regimes
of its implementation
