DEVELOPMENT OF TECHNOLOGY FOR PRODUCING SORBITOL FROM WHEAT STRAW CELLULOSE

The aim of the work is to develop an enzymatic technology for processing wheat straw cellulose for the production of sorbitol by means of hydrolytic hydrogenation based on the use of a hybrid process. Enzymatic hydrolytic hydrolysis and hydrogenation of wheat straw cellulose research have been carried out and optimal process parameters have been developed. As a result, a combined (hybrid) hydrolysis-hydrogenation process for production of sorbitol have been implemented. In this process, enzymes have been developed and tested for their activity. The influence of the process time, the temperature of the test and the pH on the conversion of cellulose and selectivity for sorbitol have been studied. The developed technology will allow us to improve the traditional processes in terms of eliminating the numerous stages of purification and isolation of intermediate products. It enables the realization of a single-reactor combined (hybrid) process for the production of such a valuable chemical as sorbitol.
