The Effects of Pulsed UV Light Implementation on the Preservation Duration of Şavak Cheese Made from Raw Milk

Abstract

This study aimed to investigate the effect of pulsed UV light on the the preservation of the Şavak cheese. In this study, the samples of Savak cheese (average 2 cm) that were produced from raw milk were exposed to two-sided pulsed UV light. The microbial analysis (enterobacteria, psychrophilic aerob, lactic acid, sulphate reducing bacteria, S.aureus and yeast-fungus) and chemical analysis (acidity, pH and the number of thiobarbituric acid) of şavak cheese were performed during storage time (25 days) at 4°C. According to the results, spoilage was observed in the control group after ten days, Group 1 was the best in terms of microbiological quality. When experimental samples were compared to the control group, no statistically differences were observed in terms of TBA, acidity, and pH value.
