Effects of temperature on Agrocybe chaxingu quality stored in modified atmosphere packages with silicon gum film windows

The effects of three storage temperatures (1, 3, and 5 degrees C) were determined on the quality of the edible mushroom Agrocybe chaxingu stored in modified atmosphere packages (MAP) with and without (control) silicon gum film windows. Results showed that the storage temperature had clear effects on headspace gas concentrations of O-2, CO2 and ethylene, sensory characteristics, respiration rate, ascorbic acid content, soluble solid content and electrolyte leakage. The higher storage temperature (5 degrees C) resulted in more rapid changes in the different quality parameters for the stored mushroom except in the case of storage at 1 degrees C where chilling injury occurred. The MAP with silicon gum film windows at 3 degrees C provided the best atmosphere for mushroom A. chaxingu as shown by a fact that the MAP packs with windows at 3 degrees C had better quality than the control.
