Abstract:

The effect of oxygen pressure on fresh keeping of needle mushroom was studied. A total of 100 g needle mushroom was placed in polyethylene (PE) bags with adjusted oxygen amount of 0, 20%, 40%, 60%, 80% and 100% and stored at 0-3℃. Water loss, polyphenol oxidase (PPO) activity, free amino acids, reducing sugar, malondialdehyde (MDA) and sensory index were determined in an interval of 3-7 days. Needle mushroom samples at room temperature and in air-package at 0-3 ℃ were used as the control. Results indicated that the activity of PPO, the amount of free amino acids, water loss, reduction of reducing sugar, and sensory change were the lowest in package with 80% oxygen.

Key words: needle mushroom, storage, fresh-keeping, high oxygen atmosphere package (HOAP).
