Abstract

Enzymes, particularly labile enzymes, and most particularly microorganism derived labile enzymes, are stabilized by adding thereto a stabilizing agent comprising a protein fraction obtained by extracting yeast with water at 80.degree. to 100.degree. C., mixing the clear extract with 5 - 20% wt./vol. trichloracetic acid and separating the precipitate obtained.
