Plant materials as a source of funzional-food ingredients

Analysis of chemical composition of vegetable raw materials, namely the fruit and berry raw materials growing in the Ural region, is provided in the article. The choice of the raw materials is caused by harvest stability, affordable price, and fortifying ability of a human body. The results of vitamins content, macro - and microelements, and also antioxidatic activity of fruit and berry raw materials, namely fetuses of black and red currant, cherry and mespilus, are presented. The results of a research on vitamin C content in various berries sorts revealed different contents: in mespilus it amounts from 16,7 to 66,7 %, in blackcurrant berries - from 78,3 to 623,3 %, in red currant berries - from 66,7 to 83,3 %, in cherry berries - from 58,3 to 75,0%. Therefore, it allows to satisfy the daily vitamin C requirement of an organism, at recommended 60 mg. Calculation of B1 vitamin consumption in 100 grammes of mespilus berries allows to satisfy the daily requirement for 7,3-10,9 %, blackcurrant berries for 6,4-8,1 %, red currant berries for 0,9% and cherry berries for 1,8-4,5 %, at the recommended amount of 1,1-1,2 mg. The studied raw materials possess antioxidatic activity ranging from 12,309 mmol/l equiv. (for mespilus), to 50,458 mmol/l equiv. (for blackcurrant), that proves the presence of such substances as anthocyanins, tocopherols, carotinoids and flavonoids, which have a favorable synergetic effect on a human body. The analysis of experimental research series proved, that fruit and berry raw materials in frozen state practically fully maintain their chemical composition for a long period of time.
