Abstract

The effect of $CO_2$ concentration on the post-harvest physiology and quality of Shiitake mushroom (Lentinus edodes) were investigated during CA storage. The respiratory rates of the mushroom stored in CA conditions were abruptly increased in proportion to $CO_2$ concentration after 40 days, and then declined, while that of the mushroom in air was continuously decreased throughout storage period. Large amounts of ethanol and acetaldehyde were produced from the 20 days CA stored mushrooms. The least changes in 5'-GMP content and electrophoresis pattern of protein in the mushroom were observed at $CO_2$ concentration of 2% during storage. Based on the changes in quality factors of the mushroom during storage, it could be concluded that $CO_2$ concentration of 2% with fixed $O_2$ concentration of 2% was more effective in extension of the freshness than any other $CO_2$ level in this experiment.
