Abstract
Straw mushroom (Volvariella volvaceae) generates rapid browning on the cap after harvest.
In the present study, controlled atmosphere of O2 and CO2 at 15°C were applied to straw mushroom in order to reduce the browning.
Gaseous combinations of 1% O2+10% CO2, 15% O2+10% CO2 and 15% O2+20% CO2 delayed and decreased the browning symptoms and could extend the storage life to at least 6 days, compared to 2 days of control (normal air at 15°C). However, interestingly, the application of 1% O2+20% CO2 accelerated the browning generation related to the higher activity of polyphenol oxidase (PPO).
