VYQZNB

Abstract

Potato tubers are one of the most common and valuable food products in the world. In the Kemerovo region - Kuzbass, 14 varieties of potatoes are grown, of which 9 are of domestic selection and five are foreign, the gross potato harvest increases annually. Kuzbass is working to improve varieties of food potatoes, which are distinguished not only by a good harvest, but are also in demand by consumers due to their high-quality culinary qualities. The purpose of the work was to assess the quality of various varieties of food potatoes grown in the conditions of Kuzbass. The objects of the study were five varieties of potatoes, including early-ripening (Gala, Mia) and mid-ripening (Arizona, Alouette, Baltic Rose) types of ripening. When performing research, we relied on current regulatory documents and standard methods of analysis. Additionally, the degree of darkening of the tuber pulp after cleaning, the content of starch and ascorbic acid, the amount of waste obtained during cleaning of tubers were analyzed, since these indicators characterize the consumer and culinary qualities of potatoes. As a result of the studies, it was found that the Mia, Gala and Arizona varieties are more stable during storage, while the Baltic Rose and Alouette varieties are less stable during storage (darke­ning was observed after 3 hours of storage). The starch content in the samples varied from 10.2 % (Gala variety) to 14 % (Alouette variety), the ascorbic acid content from 8.5 % (Mia, Gala varieties) to 12 % (Baltic Rose and Alouette varieties). It was found that all varieties did not exceed 15 % in terms of waste. In terms of culinary qualities, the Baltic Rose and Arizona varieties had the best technological characteristics. The results of the research allow us to conclude that the varieties Baltic Rose, Arizona and Alouette are more suitable for cultivation in Kuzbass and sale as food raw materials for food purposes.
