Production and characteristics of fish protein hydrolysate from parrotfish (Chlorurus sordidus) head

Fish byproducts are commonly recognized as low-value resources. In order to increase the value, fish byproducts need to be converted into new products with high functionality such as fish protein hydrolysate (FPH). In this study, FPH manufactured from parrotfish (Chlorurus sordidus) heads using different pH, time and sample ratio was investigated.Hydrolysis reactions were conducted under different pHs (5, 7, and 9) and over different durations...
