Abstract

Effects of irradiation with cobalt-60 gamma-rays on sterilization, storage and enzymes activity of four kinds of biological enzymatic preparations. namely trypsin, pepsin, amylase and liquid carbohydrase. wereinvestigated.The results showed that these enzymes have different sensitivity to irradiation. amylase being the most sensitive. The enzyme activity and enzyme effect of amylase were lowered with irradiation dose higher than 7 KGY. With irradiation doses between 7-10 KGY, enzyme activity of trypsin and pepsin were stable. Liquid carbohydrase can bestored more than half a year under a natural temperature with a stable enzyme activity without molding.
