Abstract

Purpose: The purpose of this study was to investigate the quality characteristics and antioxidant activity on consequent storage based on the temperature of new cultivar dew-drop pine mushroom (Lentinula edodes GNA01). Methods: Dewdrop Pine Mushroom were prepared under different storeage temperature (4, 10, $20^{\circ}C$). Results: Weight loss and hardness showed the least reduction rate when it was stored at $4^{\circ}C$ (p<0.05). The color value changed to dark brown at all storage temperatures during the storage period. When it was stored at $4^{\circ}C$, it maintained its initial color for a longer period than at different storage temperatures. With respect to the change in its viable cell count, the cells proliferated to less than 3.0 log CFU/g up to Ed: Please review the change. The earlier part was difficult to understand 2.83 log CFU/g until 15 days of storage at $4^{\circ}C$. On measuring the antioxidant activity of this mushroom, the polyphenol content was maintained without a large change until 9 days of storage at $4^{\circ}C$. The electron-donating action maintained high antioxidant activity, accounting for 81.99% until 12 days of storage from 83.08% during the initial storage at $4^{\circ}C$. When it was stored at $4^{\circ}C$, the sensory characteristics received the highest score among all items, such as appeaance, color, flavor and general preference, etc. Concolusion: In summary, new Cultivar Dewdrop Pine Mushroom (Lentinula edodes GNA01) can maintain its commercial value until the 12th day of $4^{\circ}C$ storage.
