摘要
为了探究冷冻储存对黑木耳菌包特性和子实体品质的影响,为黑木耳菌包冬季储存条件提供技术参考,以完成后熟的黑木耳菌包为试验材料,在-20℃条件下分别冷冻储存15 d和30 d,以20℃储存30 d为对照,观察测定黑木耳菌包特征、单袋产量、子实体形态特征和质构特性。结果表明,冷冻储存可抑制黑木耳菌包菌丝体生长,显著降低耳片硬度、弹性和咀嚼度,增加第1潮耳片产量。冷冻储存对耳片泡发率、黏聚性和回复性影响不显著。冷冻储存时间越长,第2潮耳片产量和单袋产量越低,耳片越薄,耳片弹性越低。
In order to explore the effect of frozen storage on the cultivation bag characteristics and fruit body quality of Auricularia heimuer,to provide technical reference for its storage conditions in winter,the culture bag after ripening was selected as the test material,which was respectively stored at-20℃for 15 days and 30 days,and stored at 20℃for 30 days as the control.The characteristics of cultivation bag,yield,fruit body morphology and texture of A.heimuer were observed and measured.The results showed that frozen storage inhibited the growth of A.heimuer mycelium,significantly reduced the hardness,elasticity and chewiness of fruit bodies,and increased the yield of first flush.The effect of frozen storage on the blistering rate,adhesiveness and recovery of fruit body is not significant.The longer the frozen storage time,the lower the yield of second flush fruit body and single bag yield,and the thinner the fruit body.
