Abstract

This project is aimed at the development of automatic analytical procedures for the determination of glycerol, dextran, acetic aldehyde, lactic acid and succinic acid in fermented wine originating from alcoholic fermentation. These substances are indicators of the evolution of the fermentation process, given that these determinations make it possible to monitor and control the parameters that affect the performance of the process. The analytical procedures will be developed using analysis modules based on the concept of multicommutation and binary sampling. Enzymatic reactions will be used and detection through molecular absorption spectrophotometry. The project includes, in addition to the development of analytical procedures, the design and assembly of the analysis modules and the development of software for control and data acquisition. (AU)
