Abstract: To investigate the change of cell wall composition,Pleurotus eryngii were stored in a controlled atmosphere(CA,2% O2+30% CO2)at(22±1)℃ and 90% -95% relative humidity for 5 d and cell wall composition(Proteins,polysaccharides,chitin),chewiness and ultrastructure were analyzed over the 5 d storage period.Results showed that the chewiness of CA mushroom was higher than that in CK.CA delayed the decomposition of water soluble and 1 mol/L NaOH soluble protein,maintaining the total protein of Pleurotus eryngii cellwall.CA exerted an inhibitory influence on decomposition of water soluble polysaccharide and 10 mol/L NaOH in Peurotus eryngii cellwall.CA promoted the accumulation of water soluble,10 mol/L NaOH soluble,HCl/1 mol/L NaOH soluble chitin and delayed the decomposition of them.CA surpressed the degradation of chitin and retained the hardness and chewiness of Pleurotus eryngii.The ultrastructure photograph also showed that CA kept the integrity and stability of Pleurotus eryngii cell wall.In conclusion,CA keep a good edible quality of Pleurotus eryngii through affecting mushroom cell wall composition.
