A simplified calculation method applied to enzyme inactivation during drying.
An approximate method for solving the nonlinear diffusion problem in the case of a power-function variation of the diffusion coefficient with concentration has been applied to a drying process with simultaneous enzyme inactivation. Experimental results obtained by air drying of soybean lipoxygenase entrapped in a glucose calcium-alginate gel are in good agreement with the predicted behavior, whereas hardly any differences occur between the results obtained with the approximate method and those obtained by a numerical solution of the original model.
