Abstract

Currently, pectins are widely used in the food, pharmaceutical industry, medicine and other industries due to the ability to form gels of various strengths, to show therapeutic and preventive properties. Cucurbita maxima pumpkin is considered as a source of natural and inexpensive pectin, as well as a functional food product for use in food and pharmaceutical preparations. The aim of the study was to identify the features of the accumulation of pectin substances in the most economically significant species of pumpkin C. maxima from the VIR collection. It was found that the studied varieties differ significantly in the amount of pectin substances. The content of pectins in the conditions of the North-West of Russia varied in the range from 0.59 to 4.24% (for absolutely dry matter). The content of soluble pectins was in the range of 0.24-1.36%. The level of protopectin accumulation, depending on the genotype and conditions of the growing season, was 0.35-3.37%. Sources of high content of soluble pectin and protopectin in pumpkin fruits have been identified for their further use in breeding, food and pharmaceutical industries.

俄罗斯西北部地区葫芦果实中的果胶物质

目前，果胶由于能够形成各种强度的凝胶，表现出治疗和预防的特性，被广泛应用于食品、制药、医药等行业。南瓜被认为是天然和廉价的果胶的来源，以及用于食品和药物制剂的功能性食品产品。本研究的目的是确定VIR收集的最具经济意义的南瓜C. maxima物种中果胶物质积累的特征。结果表明，不同品种的果胶含量差异较大。在俄罗斯西北部条件下，果胶含量在0.59 ~ 4.24%(绝对干物质)之间变化。可溶性果胶含量在0.24 ~ 1.36%之间。不同基因型和生长季节条件下，原粘连素积累水平为0.35 ~ 3.37%。在南瓜果实中发现了高含量的可溶性果胶和原果胶的来源，可进一步用于育种、食品和制药工业。
