Optimization of the hydrolysis conditions (effect of temperature and pH) for the production of "udang geragau' (Acetes japonicus) hydrolysate / Noor Afiqah Muhammad Basri.

Response surface methodology (RSM) was used to optimize the hydrolysis parameters of Acetes japonicus by Alcalase 2.4L in order to obtain a hydrolysate. A Central Composite design by Design Expert 7.0.3 software created 14 runs with different conditions of parameters. The parameters were temperature...

A Central Composite design by Design Expert 7.0.3 software created 14 runs with different conditions of parameters.

The results showed that the optimum condition of % nitrogen recovery for Acetes japonicus hydrolysate about 4.025 % with pH 8 at 45 °C meanwhile percentage of degree of hydrolysis about 4.025 % at pH 6 and temperature 45.19 °C.
