Use of grape of vitis labrusca variaty in the Republic of Moldova

Abstract

Actual situation with grape of Vitis Labrusca varieties, as well as opportunities of their use are described. Results of investigations of the dynamic process of accumulation of the main nutritive substances in grape of Isabella and Noah varieties are presented. Organoleptical, as well as physical and chemical indices of juice and squash samples obtained from raw material harvested at different phases of ripening are determined. Depending on the ratio of glucides, organic acids and polyphenolic substances in grape, eventual range of non-alcoholic products that can be used widely in food industry is proposed. Principal directions of use of grape of Vitis Labrusca from the pre-ripening phase are identified: production of natural acidulants, “green juices” and derivative products (fruit and vegetable matrices).
