Effect of ozone exposure time and ozonated water replacement to control the quality of chicken meat

Survei Sosial Ekonomi Nasional in 2015 stated that Indonesia ranks as the third country with the largest consumption of chicken meat per year (Badan Pusat Statistik, 2015). Ozone is able to effectively disinfect micropolutant (Loeb, et al., 2012) and Escherichia coli (Driedger, et al., 2001) in drinking water. The objectives of this study are to evaluate the performance of the ozone exposure time and water replacement in controlling the quality of chicken meat. Ozone generator used has production and number of solubility in water around 523,67mg/hr and 0,21mg/L. The variations evaluated in this study are ozone exposure time (40, 80, and 120 minutes) and the replacement of ozonated water (twice, thrice and no replacement). The evaluated parameters were Escherichia coli, total mesophyll hyll aerobic (TBMA), protein content, pH, and water content. On the seventh day storage at 120 minutes of ozone exposure time, it was able to disinfect Escherichia coli and TBMA as much as 1.700 and 9,4×10⁸ CFU/g, while on the replacement water every 40 minutes 1,700 and 1,1×10⁹ CFU/g more than blank. While the levels of protein, moisture content, and pH on the variation of exposure time and replacement of water respectively of 17,45%; 79,85%; 4,95 and 15,70%; 80,61%; 4,91.
