<![CDATA[The study was conducted to show the histologic picture of beed digested by different concentration of PAYA papain enzyme. Twenty pieces of beed of m. femoralis, 1 x 0.5 x 0.5 cm in size, were allocated into four groups. Group I was injected with aquadest as control; group II, III, dan IV were injected with PAYA 0.25%, 0.50%, and 0.75% of the weight of meat, respectively. The samples were heated in a waterbath 65°C to activate the enzyme for 0, 15, 30, 45, and 60 minutes. Samples were then put into 10% formalin solution to stop the enzyme. The were stained with haematoxyline-eosine (HE) for histologic picture. The result shows PAYA papain enzyme starts to disintegrate myofibril in the concentration of 0.50% for 30 minutes. The higher is the concentration, the more do changes of myofibril take place in the form of inflamation, disintegration, and lysis.]]>
