Berries and large fruits of the Samara region harvest 2016 year of the collection of the research institute "Zhigulevsky garden" as a perspective raw material in the food industry
One of the most important components of the human diet is the berries and stone fruits. They are rich in sugars, organic acids and biologically active substances - antioxidants. Together, the presented indicators (chemical composition and antioxidant activity) are important for the stable operation of the human body and the technological process when processing plant materials. When analyzing the chemical composition of berries and large fruits from the collection of the Research Institute "Zhigulevskie Gardens", it was revealed that the grade of raw materials influences the determined indexes.The highest value of soluble solids is occupied by the samples of apricot (leading Krugly variety), Black currant (leading Orloviya variety), raspberry (Balzam is leading).The lowest value of soluble solids was observed in strawberry varieties Kama. Analyze berries and fruits differ in the content of organic acids slightly. The maximum content of sugars in apricot, and the minimum for black currant. In the studied fruits, the highest content of phenols was recorded in the black currant. The varieties of flavonoids are different: strawberry Festivalaya, black currant Perun, apricot Khabarovskiy and raspberry Balzam. Low results showed apricot (grade Krugly, Pogremok). The high antioxidant activity was shown by the raspberry varieties Lyubetovskaya and Balzam. The chemical composition and antioxidant activity of fruits and berries play an important role not only for the human body, but also for the technological process during their processing. For this reason, analysis of the feedstock is an important stage in the development and manufacture of food products with a directed antioxidant effect.
