Biopreservation with lactic acid bacteria is an alternative for the preservation of fishery products; in this sense, it is important to know the process conditions that allow lactic microorganisms to perform their biological function. For this reason, the aim of this research was to evaluate the biopreserving effect of Lactobacillus plantarum in raw masses of sea bass (Argyrosomus regius) for the preparation of sausages. Initially,
physicochemical characterization tests of L. plantarum (SB17) were carried out, such as resistance to different temperatures (50, 60, 70 and 80 ºC), pH (3, 4, 5, and 6), salt concentrations and nitro salts (30, 60, 80 and 100 ppm). Subsequently, the fish mass formulation was standardized with the inclusion of L. plantarum with proportions of 0.25, 0.5, 0.75 and 1, and the stability of the masses was evaluated during 8 days of storage.
The results of the characterization showed that L. plantarum (SB17) is resistant to low temperatures, tolerates a pH between 5 and 6 and is resistant to salt and nitro salts at concentrations of up to 100 ppm. Likewise, a significant reduction of the Most Probable Number (MPN) was found in the masses elaborated with the inclusion of L. plantarum (SB17) during storage. In conclusion, L. plantarum proved to be effective as a biopreservative in Argyrosomus regius fish mass.
