Influence of Modified Atmosphere Packaging on Physiological Characteristics of Tricholoma matsutake

Under the storage conditions of 2-3 ℃ and 85%-90% relative humidity,the effects of gas composition,differnet packaging materials and film thickness on the preservation of Tricholoma matsutake were explored through determining respiratory intensity,weight loss rate,browning index,cell membrane permeability and other physiochemical indexes.The results showed that a V(O2): V(CO2): V(N2) ratio of 3:20:77 and packaging in a PVC film 0.05 mm thick provided optimum preservation of Tricholoma matsutake,prolonging the shelf life to about 7 d.
