Abstract

Ozonation is a microbial inactivation technology expected to reduce microbes in fresh cow milk without compromising its nutritional content. This study evaluates the effectiveness of ozonation in reducing the microbial load in fresh cow milk from Bandung District. Using 15-minute ozone treatment, microbial levels were reduced by up to 86.6%, though only 45% of the samples achieved reductions above 50%. T-test results suggest the reductions are not statistically significant with a 95% confidence level (p > 0.05).
