Evaluation of the properties of mentarang (Pholas Orientalis) protein hydrolysate / Nurfazlika Nashrah Mohd Pauzi.

Properties of a protein hydrolysate prepared from mentarang {Pholas orientalis) mince, using Alcalase 2.4L were determined. Hydrolysis was performed using the pH-stat method. The protein hydrolysate had high protein content (43.0%) and a high yield (11.03%). It was yellowish in colour (L* = 72.98, a* = 0.42, b* = 15.15). The protein hydrolysate contain high amount of essential amino-acids (44.87%) and had Alanine and Serine as the dominant amino acids. The protein hydrolysate had an excellent solubility {9232%). Other than that, emulsifying stability index of powdered mentarang is 36.13 min. Meanwhile, foaming properties decrease with increasing time of foam (p<0.05). These results suggested that mentarang {Pholas orientalis) hydrolysates have the potential for application as an additive in the food.
