Notes:
The activity of a crude enzyme preparation extracted from hepatopancreas of the freshwater prawn, Macrobrachium-rosenbergii, was assayed for collagenolytic, trypsinolytic, α-chymotrypsinolytic, and pepsinolytic activities against collagen, lyophilized prawn tissue, and artificial substrates. At optimum pH for each activity, the enzyme preparation had collagenolytic activitiy, slight trypsinolytic and α-chymotrypsinolytic activities; and no pepsinolytic activity. Of the commercial enzymes tested, only collagenase significantly degraded lyophilized prawn tissue. These results suggest that the prawn enzyme preparation may contain a collagenolytic portion which might affect the texture of the prawn.
