Production of pumpkin pectin paste

Abstract

The expediency of using vegetable-fruit pastes with a high content of pectin for the therapeutic and prophylactic nutrition of people and excretion of radionuclides, heavy metals and toxins is substantiated. The aim of the research is the development of a technology and a small-sized line for the production of concentrated pumpkin pectin pastes with preservation of plant nutrients that have the properties of removing radionuclides, heavy metals and toxins from the human body. Pectin pastes were made from the pumpkin sort Hybrid 75. In the experiments, a method for the preparation of pectin-containing pastes has been realized by hydrolyzing the plant material with the lactic acid and curd whey, which are simultaneously preserving agents. Technological operations for the production of the pectin-containing paste from pumpkin, optimized by the hydromodule of hydrolysis of the raw materials, the temperature, and the length of the process and the method of evaporation of the reaction mass, which provides better extraction of the complex of natural vitamins, tannins and sugars from the raw materials with pectin, more complete preservation of the native properties of the pectin substances, what helps to achieve the high quality of the finished product. The technology and the line for the production of pumpkin pectin pastes and other pectin-containing raw materials have been developed, what provide the preservation in the production of the native plant fruit properties. The developed technological and hardware-technological schemes of the pectin pastes production make it possible to organize their release in places close to the cultivation of raw materials and reduce transportation costs.
