Physicochemical characterization and microbiological analysis of Oligosarcus robustus raw fish meat and development a fish hamburger

Abstract

This study aimed to evaluate the microbiological, physicochemical and fatty acid profile of the of “Tambica” (Oligosarcus robustus) raw fish meat and develop and characterize a fish burger. The fish burger was subjected to a sensory analysis. The raw fish meat showed a high content of moisture (82.3%) and minerals (3.1%), a low content of fat (1.5%) and a considerable protein content (13.1%). The raw fish showed a high count of positive coagulase Staphylococcus. Tambica lipid fraction was composed of 41.9% unsaturated and 58.2% saturated fatty acids. Palmitic acid and oleic acid were the major fatty acids in the raw meat fish. The fish burger was well accepted by sensory analysis.
