✦ Synopsis

A study on preparation of industrial glucoamylase irradiated by "Co gammaray showed that an abvious change took place in the extraviolet absorption spectrum and the pHvalue of the enzyme solution and the activity of the enzyme preparation was much more resistant to irradiation than that of microbes contained in the preparation. The result indicates that Irradiated glucoamylase preparation is not only favourable to activity preservation but also is improved in the hygienic quality of products. A comparison of the various properties of Irradiated enzyme preparation with those of unirradiated one has proved that Irradiation does not change the normal application of glucoamylase preparation.

Effects of irradiation with cobalt-60 y-rays on sterilization, storage and enzymes activity of four kinds of biological enzymatic preparations. namely trypsin. pepsin. amylase and liquid carbohydrase. were investigated.The results showed that these enzymes have different sensitivity to irradiation.
