Ambient shelf life of chicken sausages fermented with Pediococcus cerevisiae
Abstract
Physicochemical, microbiological and sensory quality of chicken sausages fermented with Pediococcus cerevisiae were evaluated during room temperature storage (28±1°C). Significant (P<0.05) decrease in moisture and pH and increase in crude protein, ether extractives, titrable acidity and TBA values were observed on 6th day of storage. Counts of total aerobes, lactic acid bacteria, anaerobes and yeast and moulds increased significantly, whereas coliform and staphylococcal counts decreased during storage. Organoleptically, there was a significant (P<0.05) reduction in appearance, flavour, texture and overall acceptability scores on 6th day, yet the panelists liked the product. This indicated that the chicken sausages fermented with Pediococcus cerevisiae had shelf life of six days at ambient (28±1°C) temperature.
