Mejoramiento de la textura de un producto reconstituido de trozos de camarón empleando la enzima Transglutaminasa

Abstract

The Ecuadorian Coast hosts different species of shrimp of high quality and commercial interest, among them Litopenaeus vannamei stands out due to its greater adaptation in aquaculture. Shrimp fulfills the highest potential of raw material, when it is transformed into products that contain greater added value due to its organoleptic characteristics and excellent quality, in the wide range of seafood. In addition, part of the shrimp harvested or extracted from the sea is not exported, since there is a sub-product that does not meet the requirements of importers because it is cut up and is known as local sale or broken shrimp. The enzyme transglutaminase with its properties of binding protein is a key ingredient to reconstitute these pieces of low commercial value. The objective of this study was to develop a reconstituted food product based on pieces of shrimp with better adhesion and compaction in the crustacean meat protein. The acceptability of this enzyme in the processed product was evaluated by sensorial analysis, obtaining more preference the products with transglutaminase for their texture and flavor, it should be noted that the organoleptic characteristics and the nutritional content of the shrimp were not altered according to the analyzes carried out.
