摘 要：
为了延长黄蘑菇的保鲜期,利用酸性电解水(acidic electrolyzed water,AEW)、短波紫外线(short-wave ultraviolet,UVC)和臭氧(O3)对采后黄蘑菇进行单一和复合保鲜处理,观察黄蘑菇经保鲜袋包装和低温储藏后外观品质的变化,并检测其褐变度、硬度、失重率以及多酚氧化酶(polyphenoloxidase,PPO)、苯丙氨酸解氨酶(phenylalanine ammonia-lyase,PAL)活性等指标数据。结果表明,UVC和O3处理均能够有效延长黄蘑菇的保鲜期,4℃冷藏可使黄蘑菇的保鲜期从10d延长至42 d;而AEW并不适合用于含水量较少的高原黄蘑菇的保鲜,外来水分的带入反而会加速黄蘑菇的腐烂。研究结果对于黄蘑菇保鲜具有理论指导意义。

摘 要：
In order to prolong the preservation period of Armillaria luteo-virens,acidic electrolyzed water( AEW),short-wave ultraviolet( UVC) and ozone( O3) were used to carry out single and compound preservation treatment on the harvested Armillaria luteo-virens. The changes of appearance quality of Armillaria luteo-virens after being packaged in preservation bags and refrigerated at low temperature were observed,and the browning degree,hardness,weight loss rate and the activities of polyphenoloxidase( PPO),phenylalanine ammonia-lyase( PAL) were also detected. The results showed that both UVC and O3 treatments could effectively prolong the preservation period of Armillaria luteo-virens,and cold storage at 4 ℃ could prolong the preservation period of Armillaria luteo-virens from 10 d to 42 d. However,AEW was not suitable for preservation of Armillaria luteo-virens with less water content,due to the introduction of external moisture accelerating its decay. The research results have theoretical guiding significance for the preservation of Armillaria luteo-virens.
