| Description |
Protein hydrolysate was prepared from visceral waste proteins of Catla (Catla catla), an Indian freshwater major carp. Hydrolysis conditions (viz., time, temperature, pH and enzyme to substrate level) for preparing protein hydrolysates from the fish visceral waste proteins were optimized by response surface methodology (RSM) using a factorial design. Model equation was proposed with regard to the effect of time, temperature, pH and enzyme to substrate level. An enzyme to substrate level of 1.5% (v/w), pH 8.5, temperature of 50 degrees C and a hydrolysis time of 135 min were found to be the optimum conditions to obtain a higher degree of hydrolysis close to 50% using alcalase. The amino acid composition of the protein hydrolysate prepared using the optimized conditions revealed that the protein hydrolysate was similar to FAO/WHO reference protein. The chemical scores computed indicated methionine to be the most limiting amino acid. The protein hydrolysate can well be used to meet the amino acid requirements of juvenile common carp and hence has the potential for application as an ingredient in balanced fish diets.
