This paper is devoted to novel scientific findings, which, is properly exploited, can contribute to food security both, locally and globally. Specifically, the presented paper reports on the analytical characteristics of pectic substances derived from Cucurbita cultivated in the Republic of Kazakhstan. The fractional composition of pectic substances, their analytical characteristics and degree of etherification, content of organic acids, sugars, vitamins and mineral substances are studied. The results demonstrated that these raw materials can be considered a source of pectic substances, carbohydrates, vitamin C, a niacin and carotene. Moreover, pectic substances of Cucurbita are low-etherified, a characteristic implicated in expediency of their use as detoxicator.
