Centesimal, microbiological, and sensory characterization of fishburgers made with mechanically separated meat of tilapia

Abstract

This work aimed to evaluate the microbiological, sensory and centesimal characterization of four kinds of fishburgers elaborated with tilapia mechanically separated meat. The microbiological analyses showed that both raw material and fishburgers met the microbiological standards for products derived from fish and certified that the use of byproducts derived from fish processing is a form of aggregating value to a final product, with good acceptance by the consumer, assisting quality standards. It was not verified significant differences for the averages attributed for taste, aroma, softness, global appearance and purchase intention that ranged, respectively, from 7.14 to 7.44; 7.14 to 7.46; 7.30 to 7.42; 7.21 to 7.35; 3.86 to 3.98. All fish burgers were moderately and very accepted and did not have a preferred specific one. The results of purchase intention oscillated between “maybe would buy”/”wouldn’t buy” and “possibly would buy the product”. The physical-chemical analysis presented the following results: 15.50 to 16.14; 1.73 to 10.28 and 1.12 to 2.44 g/100 g for crude protein, ethereal extract and mineral matter, respectively. The unit cost ranged from R$ 0.36 to R$ 0.37 with yield of 12 units/kg, that denote the production viability.
