Bioactive peptides from by-products of shrimp processing: A review

Rodríguez-Jiménez, J. M. J. and Anaya-Esparza, L. M. and Martínez-Montaño, E. and Montalvo-González, E. and García-Magaña, M. L. (2024) Bioactive peptides from by-products of shrimp processing: A review. International Food Research Journal (Malaysia), 31. pp. 530-550. ISSN 2231 7546

Currently, the mismanagement of marine by-products (head, skin, guts, blood, and bones) is a problem for the seafood processing industry, causing economic losses and environmental problems. Shrimp is a high-protein marine plankton species, and after processing, 45% of the total weight is discarded. Therefore, processes must be developed to recover biomolecules from this waste. Hydrolysis of shrimp by-products is an efficient way to add value to the protein for the extraction of bioactive peptides. The present review focuses on recent research on the use of marine by-products to obtain bioactive peptides, especially those from shrimp waste, and discusses their benefits for human health. Protein hydrolysates from shrimp by-products are a viable and technological strategy to obtain peptides of different sizes and improved antioxidant, anti-hypertensive, antiinflammatory, and hypocholesterolaemic activities.

Abstract

Currently, the mismanagement of marine by-products (head, skin, guts, blood, and bones) is a problem for the seafood processing industry, causing economic losses and environmental problems. Shrimp is a high-protein marine plankton species, and after processing, 45% of the total weight is discarded. Therefore, processes must be developed to recover biomolecules from this waste. Hydrolysis of shrimp by-products is an efficient way to add value to the protein for the extraction of bioactive peptides. The present review focuses on recent research on the use of marine by-products to obtain bioactive peptides, especially those from shrimp waste, and discusses their benefits for human health. Protein hydrolysates from shrimp by-products are a viable and technological strategy to obtain peptides of different sizes and improved antioxidant, anti-hypertensive, antiinflammatory, and hypocholesterolaemic activities. Therefore, the reuse and valorisation of shrimp by-products by obtaining bioactive peptides is an active research area, with potential applications and beneficial effects for human health, the environment, and the economy. However, further studies are needed to ensure their safe use, and to understand their mechanism of action.
