Abstract:

Protein from swimming crab was hydrolyzed by alcalase, and a kinetic model for the hydrolysis was established. Results suggested that the degree of hydrolysis (DH) increased with increasing of initial enzyme concentrations, and tapered off with increasing of initial substrate concentrations at temperature 55 ℃ and pH 8.5. The hydrolysis kinetic model was expressed as DH=3.558ln[1+(2.553E0/S0+0.116)t]. The theoretical DH from the hydrolysis kinetic model is consistent with the practical DH.

Key words: swimming crab, protein, enzymatic hydrolysis, kinetics
