БІОЛОГІЧНА ЦІННІСТЬ ПЛОДІВ МАЛИНИ

Abstract

The human body needs a constant flow of biologically active substances. Berry products, including raspberries, are a source of natural and affordable BAS. Raspberry berries contain a complex of BAS, in particular fructose, glucose, organic acids, vitamins A, B1, B2, C, P, E, essential oils, pectins, fiber, complex of polyphenols, copper salt, iron, potassium, folic acid, etc. Berries are salicylic acid and can for a long time maintain the beneficial properties of various processed products. Berries contain a lot of food fibers, it is beneficial for digestion. Berries contain betasitosterol and anthocyanins have anti-sclerotic properties, and coumarins normalize blood coagulation. Berries contain a lot of food fibers, it is beneficial for digestion. Raspberry berries contain coarse dietary fiber, β-sitosterol, anthocyanins and coumarins, these substances have a positive effect on digestion, have anti-sclerotic properties and normalize blood clotting. The purpose of the research aimed at carrying out a comparative characterization of the basic biochemical substances content and the quality of various berries and raspberry hybrids grown at the research field "Fruit and Vegetable Garden" of NULES of Ukraine. During the research the complex of international and state regulatory documents were used, in particular: the berries were selected in the state of technical maturity, in accordance with the state standard 7179: 2010; the sample size corresponded to ISO 874-2002; the determination of the components of the biochemical composition was carried out: the content of dry soluble substances were determined according to ISO 2173-2013, invert sugars – state standard 4954: 2008, titrated acids – state standard 4957: 2008, ascorbic acid – ISO 6557-2: 2014; organoleptic evaluation – according to the generally accepted methodology. Based on the obtained results, it was found that among the studied samples of berry varieties Babine Lito, Sontse Kieva, hybrids – Hybrid №4a, Hybrid №2 were characterized by the highest organoleptic and biochemical parameters, therefore it is expedient to use them both for consumption in a fresh form and for processing. The obtained results should be taken into account during the planning of raspberry planting and in further selective work during the creation of competitive varieties and hybrids of raspberries with a high content of biologically active substances in berries.
