Optimization of Keli Afrika (clarias gariepinus) hydrolysate by alcalase (effect of time and enzymes substrate ratio) / Zamri Idris

The optimization of catfish hydrolysate by Alcalase was obtained from the experiment at optimum condition 137 minutes and 4% enzymes concentration with temperature 50° C and pH 7 as determined by randomized surface methodology (RSM). Whereby, the nitrogen recovered from catfish hydrolysis was optimu...
