Bioprospecção de compostos antioxidantes na fauna acompanhante da pesca demersal

Abstract

Nos últimos anos, a fauna acompanhante da pesca camaroeira vem sendo alvo de estudos por ser um dos fatores do grande impacto ambiental causado pela pesca de arrasto. Em contrapartida, esse rejeito de pesca pode ter propriedades funcionais e bioativas, como peptídeos antioxidantes, que poderiam agregar valor a esse rejeito e se tornar um produto de interesse para as indústrias alimentícias. Assim, o presente estudo visou investigar a atividade antioxidante dos hidrolisados proteicos obtidos dos animais mais abundantes da fauna acompanhante e microencapsular esses hidrolisados para agregar valor à este material normalmente descartado. Os resultados demonstram que a hidrólise enzimática, utilizando as enzimas comerciais Alcalase 2.4 L® e Protamex®, é um método eficiente para liberar peptídeos de interesse econômico nas duas espécies mais abundantes de peixes (Micropogonias furnieri e Paralonchurus brasilensis) e nas duas mais abundantes de crustáceos (Callinectes ornatus e Hepatus pudibundus). A hidrólise liberou peptídeos com atividade antioxidante em todas as amostras analisadas, submetidas às duas enzimas testadas. A coacervação complexa e subsequente microencapsulação por spray-drying mostrou-se eficiente para proteger a atividade antioxidante desses hidrolisados proteicos. Assim, os resultados fornecem evidências para o potencial uso dos hidrolisados das espécies analisadas como ingrediente funcional ou nutracêutico na indústria alimentícia.

In recent years, the bycatch of shrimp fishing has been the subject of studies as it is one of the factors of the great environmental impact caused by trawling. However, this bycatch can have functional and bioactive properties, such as antioxidant peptides, which could add value to this reject and become a product of interest to the food industries. Thus, the present study aimed to investigate the antioxidant activity of protein hydrolysates obtained from the most abundant animals of the bycatch and to microencapsulate these hydrolysates to add value to this normally discarded material. The results demonstrate that enzymatic hydrolysis, using the commercial enzymes Alcalase 2.4 L® and Protamex®, is an efficient method to release peptides of economic interest in the two most abundant species of fish (Micropogonias furnieri and Paralonchurus brasilensis) and in the two most abundant crustaceans (Callinectes ornatus and Hepatus pudibundus). Hydrolysis released peptides with antioxidant activity in all samples analyzed, submitted to the two enzymes tested. Complex coacervation and subsequent microencapsulation by spray-drying proved to be efficient to protect the antioxidant activity of these protein hydrolysates. Thus, the results provide evidence for the potential use of hydrolysates of the analyzed species as a functional or nutraceutical ingredient in the food industry.
