Abstract
A process is provided for decreasing the thermal stability of Mucor microbial rennet without substantially reducing its milk-clotting activity by contacting an aqueous solution thereof with a methionine-oxidizing means under conditions effective substantially to decrease the thermal stability of the microbial rennet. The resultant treated microbial rennet is dramatically less heat stable than untreated microbial rennet and can serve as replacement for calf rennet in traditional cheese-making processes. The preferred methionine-oxidizing means is hydrogen peroxide or dye-sensitized photooxidation.
