The effects of nisin, oil–wax coating and yogurt on the quality of refrigerated chicken meat

Evisceration makes chicken carcasses susceptible to microbial contamination from gastrointestinal sources. A preventive action between spray washing and air chilling, a yogurt dip, may eliminate concerned contamination and enhance the bactericidal effect of nisin on Salmonella. This study was designed to determine whether synergism occurred with or without the application of an oil–beeswax coating. A 5 h yogurt dip then nisin with coatingʹ and a 5 h yogurt dip then nisin, indicated significant inhibition of mesophilic aerobic bacteria and Salmonella with 2.11 and 1.97 log reductions, supported by pH, chromatographic and sensory findings (p<0.01).
