ANALYTICAL OVERVIEW OF THE TECHNOLOGIES OF SUNFLOWER PROCESSING IN PECTINE CONCENTRATES

The existing technologies for processing sunflower raw materials are analyzed. The issue of waste-free technologies introduction in the field of processing pectin-containing raw materials (sunflower) in the production of food additives is considered. The existing and developed technological schemes of obtaining high-quality pectin concentrate with minimal ecological danger are analyzed. The comparative research of the procedure of processing sunflower pectin-containing raw materials for the development of the universal scheme of the technology of pectin concentrates reception is carried out. The stages of pectin concentrate production (pectin extraction, concentration and purification) for the creation of more efficient processes of sunflower raw material processing are analyzed. It is noted that for obtaining high-purity pectin concentrates from baskets of sunflower inflorescences, it is required to pre-treat raw materials before the hydrolysis-extraction for maximum removal of ballast in relation to pectin contaminants pectin extract and significantly impair organoleptic and physicoleptic and physical.  Ready-made pectin, which is obtained by traditional and new technologies from sunflower raw materials, along with high gem forming also possesses high complexing ability. Promising directions of resource-saving processes for the creation of new waste-free technologies in the manufacture of various pectin-containing products for healthy eating are proposed. Modern research and development of scientists around the world is aimed at creating processes for obtaining pectin concentrates from sunflower through the integrated use of acid extraction of pectin substances and effective methods of concentration and purification of pectin extracts. The solution of such issues allows both to create resource-saving processes for the production of sunflower pectin concentrates, and to develop cost-effective equipment for their implementation. An improved scheme of the general technology of obtaining pectin concentrate from sunflower raw materials can be used as a plan of future research of working parameters of separate processes is presented.
