ENZYME INACTIVATION DURING DRYING OF A SINGLE DROPLET.

Abstract

The effects of various drying conditions on the enzyme inactivation during drying of a single droplet were investigated. Moisture, temperature and enzyme activity of the drop during drying were measured as a function of drying time. The enzyme inactivation rate constants and the diffusion coefficients were measured as functions of moisture content and temperature. By use of these values, the drying histories including the enzyme retention in the drop were computed and compared with the experimental results. Good agreements were observed between the experimental and calculated results.
