Study of bromelain enzyme activity on bromelain enzyme production waste as feed additive

This study aimed to know nutrient composition and bromelain enzyme activity of bromelain enzyme production waste as feed additive for animals. The waste sample were analyze by proxymate analyze (nutrient composition) and casein digestion unit method (bromelain enzyme activity). The treatment devided into 2 groups: 1. Sampel dried by sun drying; 2. Sampel dried by oven 60°C. The nutrient composition of bromelain enzyme production waste is: moisture 9.45%; ash 7.55%; crude protein 5.75%; crude fiber 2.72%; and extract ether 5.64%. Bromelain enzyme activity were do using fresh sample of waste; sample were drying by sun drying method and oven 60°C. The result showed bromelain activity: 5.14 CDU; 0.08 CDU; and 13.29 CDU. The best preparation process is by drying method using oven at 60°C which bromelain enzyme activity is 13,29 CDU/mg. It can be concluded that drying process affects the activity of bromelain enzyme.
