Abstract: Fresh Lentinus edodes was packaged using packaging films with different gas permeability and the effects of different packaging materials on the qualities of fresh Lentinus edodes were studied by measuring changes in respiration rate, weight loss rate, soluble solid content, hardness, whiteness and ascorbic acid content during storage at 4 ℃ and 90% humidity. Results indicated fresh Lentinus edodes packaged with a 30-micron film reserved the lowest respiration rate and weight loss rate, and the highest soluble solid content compared with other packaging films. The influences of films on hardness and whiteness of Lentinus edodes were not significant (P > 0.05). In the early storage the impacts of films on the ascorbic acid content were not significant (P > 0.05), while in the late storage ascorbic acid content in Lentinus edodes packaged with a 30-micron low density polyethylene film was higher than in Lentinus edodes packaged with other films.

Key words: packaging film, permeability, Lentinus edodes, preservatio
