摘要:

为研究不同氧气配比对金针菇贮藏保鲜效果的影响,在PE 聚乙烯塑料袋(20cm × 30cm,厚度0.5~1mm)中放入100g 金针菇,分别按0、20%、40%、60%、80%、100% 氧气配比充气包装(以氮气调节其气体组成),包装袋封口后放入温度为0~3℃的冷库进行贮藏,同时设立空气包装的金针菇于室温或低温贮藏作为对照。每隔3~5d 取样一次,评定其水分损失率、多酚氧化酶(PPO)活力、丙二醛含量、游离氨基酸含量、还原糖含量和感官指标等。结果表明,在氧气配比为80% 的包装时,其PPO 酶活力、丙二醛、游离氨基酸含量最低,水分损失和还原糖损失最少,感官变化最小,贮藏保鲜效果最好。采用高氧气调包装(HOAP)金针菇贮藏保鲜35d 仍有较好的商品品质。

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).
