Description
Summary:The present investigation was carried out in the Laboratory of Bromatology, located in the Experimental Farm "La María" of the State Technical University of Quevedo, located at km 7 ½ of the Quevedo - El Empalme road, San Felipe Campus; Canton Mocache, Province of Los Ríos. The same objective was to evaluate the effect of lactic acid bacteria as a preservative in the conservation of chicken carcasses in the Quevedo canton. The study was carried out with a completely random design in 3 x 3 factorial arrangement with 3 repetitions, as the first factor A: lactic acid bacteria extracted from the cocoa mucilage (National) and Factor B: time, resulting in 9 trématenos and 3 repetitions. The results obtained were analyzed in the statistical program Infostat, for the comparison of the means of the treatments a tukey test (p≤ 0.05) was used. which showed that there are significant differences, resulting that: 10% of cocoa mucilage reports the lower presence of E. coli and total coliforms, lower value in pH and temperature; At 6 hours there is a lower presence of E. coli and at 0 hours total coliforms, the lowest pH values are at 12 hours and temperature at 0 hours. The highest concentration of lactic acid bacteria was reported at 0 hours in 5, 10 and 15% of cocoa mucilage with 1.1 x 107 CFU and the lowest concentration was recorded at 12 hours in 15% of cocoa mucilage with 1, 6 x 105 CFU, so the hypothesis is accepted "The use of lactic acid bacteria increases the shelf life and decreases the degree of contamination of chicken meat." Key words: Mucilage, lactic acid bacteria, conservation, microbiological
