Avaliação microbiológica da silagem biológica de resíduos de pescado das indústrias de filetagem de tilápia do Nilo (Oreochromis niloticus)

Abstract

The experiment is to evaluate the biological silage waste from industrial fish filleting of Nile tilapia (Oreochromis niloticus). With the goals of increasing the income and production industry, and consequently minimize the environmental and health problems, from the fish waste, proceeded to the preparation of silage biological waste processing of the Nile tilapia (Oreocrhromis niloticus ) after homogenization using the fish waste and leftover cabbage (Brassica oleracea), papaya (Carica papaya), wheat flour , red wine vinegar and salt, for the preparation of yeast to maintain the pH at about 4.0. Were evaluated silages stored for microbiological analysis of Salmonella, total coliforms, fecal coliforms and Escherichia coli and microbial counts. There was a significant reduction in microorganism count duringstorage at room temperature, but this effect was more pronounced after the second week standing at l0 count below 3 CFU / g, sufficient to ensure good stability of the product by 180 days.
