Biologically active compounds form seafood processing by-products

Abstract

Every year a considerable amount of seafood is discarded as processing leftovers and current estimates revealed that the discard exceed over 20 million tons equivalent to 25 % of the total production. Common seafood processing by-products, including fish oil, fishmeal, fertilizer, pet food and fish silage, generate low income compared to that of effort employed to recycle the waste. Recent advanced biotechnology and biochemistry research has identified number of biologically active compounds form seafood processing by-products while giving a new insight to the classical by-product industry. Exploration of seafood processing leftover for bioactive compounds brings high value for the processing by-products. In this chapter focus was given for comprehensive understanding of seafood processing by-products, exploration of bioactive compounds and biological activities of by-product-derived compounds.
