TECHNIQUE AND TECHNOLOGY OF USING CARBON DIOXIDE IN SUB- AND SUPERCRITICAL STATE

Abstract

Summary. Solving problems of deep processing of agricultural raw materials is largely dependent on the use of biotechnological methods of processing raw material components, the use of high-tech methods for the purpose of long-term storage of raw materials, preparative separation of the chemical components of raw materials, creation of natural food supplements based on secondary agricultural inputs. It is known that modern processes of agricultural raw materials are accompanied by changes in gas-liquid media in a wide range of humidity, temperature and pressure. Gas-liquid technology effectively influence the flow of raw materials, which acquires new characteristics or quality can be divided into separate classes of chemical compounds. Results of author’s researches in the area of agricultural raw material gas-liquid treatment are represented in the article. Idea of new scientific direction - unified system of carbon dioxide application in the branches of food industry for creation of principally new high technologies of various origin raw material. Technological opportunities vegetative and animal raw material gas-liquid treatment for production of highly concentrated natural food agents have been analyzed. Application of carbon dioxide as extraction agent in sub- and supercritical state made possible to solve several problems of vegetative raw material chemical components preparative separation, activate the activity of animal raw material inner enzymes, achieve the raw material hyperfine de-composition by method of gas-liquid explosion.
