Abstract: In the present study, local mushrooms were stored at 4 ℃ with 2.14, 4.28, 6.42, 8.56 mg·m-3 ozone treatment, respectively. Based on sensory evaluation and changes of nutrition quality and enzyme activity, the effects of ozone treatment on the postharvest quality of shiitake mushroom were studied. It was shown that 4.28 mg·m-3 ozone treatment showed better effects in preventing the decomposition of nutrients and membrane lipid peroxide, and thus favored anti-aging as well as keeping good commodity value. However, higher concentration of ozone may cause metabolic disorder and result in decline of shiitake mushroom quality.

Key words: shiitake mushroom, ozone, postharvest quality, food preservation
