Influence of some preservatives on the bioactivity of digestive enzymes

ABSTRACT

The effect of seven commonly used preservatives on the biological activity of chymotrypsin, diastase, pepsin, pancreatin and trypsin were studied by the radial diffusion technique. The proteolytic activities of papain, pancreatin and chymotrypsin were reduced by the tested preservatives in descending order, while those of pepsin and trypsin were unaffected. Reductions in the amylolytic activity of pancreatin and diastase varied according to the preservative tested
