Global environmental degradation in almost all regions of the world dictates the need for expansion of a range of specialized products with powerful detoxification properties. Another equally urgent problem is an increasing output of competitive products per one unit of processed agricultural products. Pectic substances are effective plant-based sorbents. Cucurbit crops, such as desert gourd and watermelon, present promising raw materials for pectin production. Due to high pectin content, pulp and juice of their fruits, in particular desert gourds, have high viscosity and special consistency. Here we show the results of analysis of the total content of pectin substances and their fractional composition (mass fraction of protopectin and hydrated pectin). The results obtained formed the basis for development of an innovative technology for desert gourd and watermelon processing with production of pectin products. To evaluate fields of their applications, basic analytical characteristics of pectin’s were studied: content of free and methoxylated carboxyl groups, degree of esterification, methoxyl and acetyl moieties, and complexing ability. A characteristic of isolated pectin’s allowed us to evaluate the feasibility of cucurbit crop processing for expansion of the range of pectin-containing foods and increase of their production volumes. We also show data on the global and Russian food markets of pectin-containing foods.
