Abstract: The present study is to explore the nutritional aspects of protein hydrolysate of Tuna (Thunnus albacores, Bonnaterre, 1788) emphasize on biochemical composition, and minerals. Protein hydrolysate was prepared from Dark and White meat of Tuna by enzymatic hydrolysis. Enzyme digestion was carried out with the enzyme Papain. Nutritional evaluation of fish includes moisture TDMH 9.4% and TWMH 10%, Protein TDMH 72% and TWMH 70%, Fat TDMH 3.32% and TWMH 3.9%, and Ash TDMH 12.95% and TWMH 13.42% respectively. Minerals were found in a significant level in both the fish Phosphorous TDMH 1483mg/100g and TWMH 1657mg/100g, Potassium TDMH 26.89mg/100g and TWMH 31.92mg/100g Calcium TDMH 593.84mg/100g and TWMH 626.34mg/100g, Sodium TDMH 27.04mg/100g and TWMH 35.21mg/100g and Iron TDMH 88.2mg/100g and TWMH 196.8mg/100g. The heavy metals illustrated were Copper, Manganese, Zinc, Magnesium, Mercury and Chromium present in both the protein hydrolysate. The knowledge about the biochemical composition of the fish enhances the utility of the fish as good source of quality protein.
Keywords: Heavy metals, Mineral analysis and Proximate composition.
