Abstract: The aim of the present study is to compare the effect of three different kinds of cling film, including low density polyethylene (LDPE) film, high density polyethylene (HDPE) film and polyvinyl chloride (PVC) film, on Pleurotus ostreatus fresh-keeping under the condition of simulated cold fresh supermarket shelf temperature and humidity [temperature around (14±1)℃, storage environment relative humidity around 85%]. The results showed that compared with the LDPE film, HDPE film and PVC film could reduce the postharvest Pleurotus ostreatus weight loss, maintain the high CO2 volume fraction and low O2 volume fraction in packing. During the first 4 d of storage, Pleurotus ostreatus packaged by HDPE film and PVC film had no significant difference with Pleurotus ostreatus packaged by LDPE film(P>0.05). But after 4 d storage, the sensory score of Pleurotus ostreatus packaged by HDPE film and PVC film was significantly lower than the sensory score of Pleurotus ostreatus packaged by LDPE film and the respiration intensity and cell membrane permeability were also significantly higher than Pleurotus ostreatus packaged by LDPE film (P<0.05). Under the condition of Pleurotus ostreatus packaged by LDPE, the fresh-keeping effect was the best.
