dc.description.abstractAlicyclobacillus acidoterrestris survives during the typical pasteurization process and can cause the spoilage of fruit Juices thanks to its spore forming and thermo-acidophilic nature. In recent years, A. acidoterrestris has become a major concern to the fruit juices industry worldwide. This study was undertaken to evaluate ozone for the reducing number of A. acidoterrestris spores in apple juice. Apple juice inoculated with A. acidoterrestris spores was bubbled with continuous stream of two different constant concentrations (2.8 and 53 mg/L) of ozone at 4 and 22 degrees C up to 40 min. Level of A. acidoterrestris spores in juice decreased by 22 and 2.8 log after 40 min of ozonation at 4 degrees C with concentrations of 2.8 and 5.3 mg/L, respectively. Treatments at 22 degrees C for 40 min with 2.8 and 53 mg/L ozone resulted in 1.8 and 2.4 log reductions of spore viability, respectively. At the ozone concentration of 53 mg/L, significant (P < 0.05) reductions were observed in total phenolic content of juice at both temperature levels. However, treatments performed at 2.8 mg/L were observed to have no significant (P> 0.05) effect on total phenolic content. The results presented in this study indicate that over the 2 log reduction in the count of A. acidoterrestris spores in apple juice can be achieved by bubbling ozonation at 4 degrees C without causing a significant decrease in total phenolic content of product Therefore, it can be suggested that bubbling ozonation is a promising method for the control of A. acidoterrestris in fruit juices.
