The use of the bacteriocin, nisin, as a preservative in pasteurized liquid whole egg.

Nisin used at a level of 5 mg/1 resulted in a significant increase in refrigerated shelf life of pasteurized liquid whole egg from between 6-11 d to 17-20 d. In the first of two trials, nisin also protected the liquid egg from growth of Bacillus cereus. Bacillus cereus was not presented in the egg in the second trial. Effective residual levels of nisin were detected in the liquid egg post-pasteurization.
