The fish processing industry produces more than 60% by-products as waste, which includes skin, head, viscera, trimmings, liver, frames, bones, and roes. These by-product wastes contain good amount of protein rich material that are normally processed into low market-value products, such as animal feed, fish meal and fertilizer. In view of utilizing these fish industry wastes, and for increasing the value to several underutilised fish species, protein hydrolysates from fish proteins are being prepared by several researchers all over the world. Fish protein hydrolysates are breakdown products of enzymatic conversion of fish proteins into smaller peptides, which normally contain 2-20 amino acids. In recent years, fish protein hydrolysates have attracted much attention of food biotechnologists due to the availability of large quantities of raw material for the process, and presence of high protein content with good amino acid balance and bioactive peptides (antioxidant, antihypertensive, immunomodulatory and antimicrobial peptides).
鱼类加工业产生的副产物超过 60%，包括皮、头、内脏、切块、肝、架、骨和鱼卵。这些副产物废物含有大量富含蛋白质的物质，通常加工成低市场价值的产品，如动物饲料、鱼粉和肥料。为了利用这些鱼类加工业的废物，并提高几种未充分利用的鱼类的价值，世界各地的研究人员正在制备来自鱼类蛋白质的蛋白质水解物。鱼蛋白水解物是鱼蛋白酶解转化为较小肽的产物，通常含有 2-20 个氨基酸。近年来，由于该过程有大量的原料可供使用，并且存在高蛋白含量、良好的氨基酸平衡和生物活性肽（抗氧化、降压、免疫调节和抗菌肽），鱼蛋白水解物引起了食品生物技术学家的极大关注。
