Abstract:
In this work, a cold atmospheric pressure plasma was used as a low cost and non-thermal alternative method in food industry, and it was compared with traditional pasteurization method. Dielectric barrier discharge was used to generate the air plasma for the treatment of barberry juice, in 8, 10 and 12 minutes. The effect of the plasma treatment on the color, the amount of pH, total microorganisms, mold and yeast, lactic acid bacteria, acid resistant bacteria and Aspergillus niger were investigated and the results were compared with those by 12 min thermal pasteurization method. The results show that there are no meaningful statistical differences between the 8, 10 and 12 min plasma exposures and pasteurization methods, but there are meaningful differences between these samples and the control. It means that by optimizing such plasma device, the cold atmospheric plasma treatment is an appropriate alternative method for the thermal pasteurization.
