dc.description.abstractThe formation of microcapsule calcium alginate – chitosan has been carried out and a study of activity determination of free papain enzyme and encapsulated papain enzyme is using Murachi method. The optimum activity of free papain at 55oC at pH 7 incubated for 20 minutes is 92,807 μg/ml. While the optimum activity of microcapsule crude papain at 60oC at pH 7 incubated for 20 minutes is 114,983 μg/ml. Crude papain microcapsule can be used for eight time with storage interval is one day. After eight time using, activity become 29,770 μg/ml (activity is 26%) at 25oC storage and activity of 10oC storage is 32,2μg/ml (activity is 28%).en_US
