Effect of different levels of nisin on the microbial quality of chicken cutlets

The present study was conducted to evaluate the efficacy of nisin on the microbial quality of chicken cutlets. Three levels of nisin viz. 400 I.U/g, 600 I.U/g and 800 I.U/g were incorporated in the formulation to study the effect of nisin on storage quality of chicken cutlets based on various microbiological counts. The chicken cutlets were aerobically packaged in low density polyethylene pouches along with control and evaluated for microbiological quality for a period of 15 days under refrigerated conditions (4±1 o C). The products were analyzed for various microbiological parameters viz. Total plate count, Psychrophilic count, Coliform count and Yeast and mould count. All nisin treated preparations recorded lower total plate count, psychrophilic counts and yeast and mould count as compared to control. The microbiological counts of all nisin treated products were within acceptable limits up to 15 days of refrigerated storage (4±1 o C) in LDPE bags.
