Abstract

Use of two lactic acid bacteria (LAB) Staphylococcus carnosus y Lactobacillus alimentarius, was studied as a means to preserve pork by a controlled fermentation. Pork samples were vacuum packaged and stored at 4°C and 20°C for 96 hours. Enterobacteriaceae population, used as spoilage indicator, was significantly (P>0.003) reduced in fermented samples stored at 20°C. However, at this temperature significantly changes in color (P<0.0001) and texture (P<0.0035) were observed. At 4°C functional properties were not significantly modified (P>0.730 and P>0.738 respectively). Free fatty acids concentration increased in fermented meat, causing the accumulation of linoleic, oleic, palmitic and linolenic acids.
