Fish viscera protein hydrolysates: Production, potential applications and functional and bioactive properties

- Fish viscera protein hydrolysates (FVPH) are promising high added value products.
- Nutritional, bioactive and functional properties of FVPH are useful to the industry.
- Further research about the performance and stability of FVPH are needed.
- FVPH production is considered sustainable, however there are huge challenges ahead.

The aquaculture and fishery chain is an important part of the economy of many countries around the world; in recent years it has experienced significant growth that generates more and more quantities of waste, which are mostly discarded, impacting the environment, despite having a useful chemical composition in various industrial sectors. This article presents a review of the agroindustrial potential of fish wastes, especially viscera, as a source for obtaining native protein and hydrolysates, explaining their production process, chemical composition and functional and bioactive properties that are important to the agricultural, cosmetic, pharmaceutical, food and nutraceutical industry.
