摘要
The aim of the study was to determine the effect of soaking in ascorbic acid and citric acid solution and modified atmosphere packaging on the quality of a coleslaw mix stored for 12 days at 4C. Pretreatment caused a reduction by approximate to 2 logarithmic cycles for counts of psychrophilic bacteria from the genus Pseudomonas, and mesophilic yeasts, as well as a significant decrease in the counts of mesophilic bacteria and coliform bacteria. Packaging of tested samples in modified atmosphere with high contents of oxygen (70 or 50%) and carbon dioxide (30%) caused an inhibition of growth for mesophilic, psychrophilic, lactic acid and coliform bacteria during storage. Application of atmosphere with increased contents of CO2 (25 or 30%) resulted in the inhibition of growth of bacteria from the genus Pseudomonas, while in the case of elevated (70%) or reduced contents of oxygen (5%) a slower growth of yeasts was observed.
