Effects of Chlorine Dioxide Treatment on Quality and Microbial Change of Agaricus bisporus Sing during Storage

Effects of chlorine dioxide () on weight loss, polyphenol oxidase activity, and microbial change of fresh mushrooms (Agricus bisporus Sing) were investigated. Mushrooms were treated with 5, 10, and 50 ppm of solution. Mushrooms were stored at room temperature and . Weight loss for treated mushrooms was smaller than that of the control group. Polyphenol oxidase activity of the samples stored at room temperature increased until day 2 of storage and then decreased, and the activity of the samples stored bacteria, yeast and mold counts than the control during storage. Aerobic bacterial counts for 50 ppm of treatment at increased from at day 10 of storage, while control groups were from . These results indicate that treatment could be useful in improving the quality and microbial safety of mushrooms.
