The objective of this thesis is to ensure utmost performance of the diffusion process by choosing the most effective components of chemical heat treatment of beet chips. Aqueous solutions of ammonia sulphates (NH 4 ) 2 SO 4 , aluminium sulphate Al 2 (SO 4 ) 3 , calcium sulphate CaSO 4 have been considered as reagents to process chips. The classical diffusion process method has been used as a benchmarking option. It has been deduced from experiments that beet tissue treatment with solutions of the proposed reagents heated up to 73 ° C enables a high degree of cell plasmotosis, enhances its permeability and intensifies sucrose transfer to the extractant during heavy convectional leaching. The process is strongly enhanced if chips are treated with reagent solutions following electrochemical activation, which is confirmed by the study of the beet tissue fine structure after its various chemical heat treatments. Rational conditions of solution electrochemical activation for beet chips chemical heat treatment prior to extraction have been selected experimentally. 3 patents of the Russian Federation for the diffusion juice process have been obtained based on the results of the studies conducted.
