Fish protein hydrolysate production, treatment methods and current potential uses: A review


Author(s): Aurobinda Das, Yashaswi Nayak and Supriya Dash

Abstract: About 20 per cent of the live weight of freshwater fish is visceral mass is a rich source of protein, lipids, polyunsaturated fatty acids, soluble vitamins, phospholipids etc having very great source of agro industrial products. Any scientific technique that uses strong squanders coming about because of fish harvesting by recuperating biomolecules like lipids and proteins brings about extra income as well as helps to reduce the dumping issues related therewith. Visceral fish hydrolysate (also known as fish protein hydrolysate; FPH) has drawn the interest of many researchers in recent years due to its great utility in the fields of food, pharmaceuticals, cosmetics and nutrition. The extraction or production of FPH including predefined sequential steps like collection of raw materials, pretreatment (alcohols, heat treatment, press technique coupled with heat treatment), hydrolysis (acidic, alkaline, enzymatic) and recovery of FPH using spray drying, lyophilisation, centrifugation or nanofiltration. The extracted FPH is characterized for molecular mass, protein content, structure of protein, IR, XRD etc to analyse the chemical nature of the FPH. It is widely used as emulsifier, binder, gelling agent, fertilizer, crayoprotectant and dietary additives in various industries. FPH has been used as potential source of microbial growth media for gram positive and negative microbes, nutritional supplement due to higher protein content (60-90%), and antioxidant, antihypertensive and antimicrobial agent. FPH is also used as nutriceuticals and some of the products are commercially available in various countries including US, Canada, UK. Considering the physicochemical difficulties associated with FPH, its excellent nutritional and functional properties generate possibilities for its usage in both the food and health industries.
