This article provides an analysis of the current state of technology and technology for the production of pectin.The demand for pectin is more higher than the volume of its production. The use of pectin is justified, it is extremely necessary in conditions of environmental degradation and environmental pollution. The quality of the final finished product pectin, depends not only on physical and chemical processes, but also to large extent on the quality and method of preparation of pectin-containing raw materials. It also an important side in the production of pectin is occupied by the processes of the preparation of pectin-containing raw materials, hydrolysis-extraction and precipitation of pectin substances, on the correct implementation of which the yield and physicochemical indicators of the target product depends on. In this regard, the preparation of pectin-containing raw materials, research and development of technological modes and processes for the preparation of cotton fiber, as a new type of raw material, are relevant and have great scientific and practical importance. As a result of the study, technological regimes, processes and methods for preparing a cotton fiber for the release of pectin substances have been established and developed: -the most acceptable parameters for drying cotton fiber; -the influence of long-term storage within 24 months of dry cotton fiber in the fiber composition and physicochemical parameters of pectin; the optimal size of the laminae of cotton fibers and in the process of hydrolysis-extraction; the proposed scheme for cleaning the cotton fiber from polyphenols; the process of swelling of dry cotton fiber. Based on the research results, a technological line for the production of pectin from a cotton fiber has been developed. The pilot industrial production of powdered pectin has been mastered at the established experimental production “Pakhta” in the Chinaz district of the Tashkent region.
