大闸蟹能不能冰冻保存,请问大闸蟹能不能冷冻起来保存?
据和记百科网站「木已凉兮」消息,近日,大闸蟹能不能冰冻保存,请问大闸蟹能不能冷冻起来保存?引发热议,大闸蟹能不能冰冻保存同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?和记百科为您解答。
活的大闸蟹不能冷冻起来保存,熟的大闸蟹可以冷冻起来保存。将活的大闸蟹放进冷冻层之后,由于温度在0度以下,大闸蟹会被冻死,肉质会变得不新鲜;另外,活的大闸蟹在冷冻之后,蟹肉会缩水,下次拿出来吃的时候,蟹肉会变干,口感不佳。而煮熟的大闸蟹在冷冻的时候蟹肉并不会缩水,再加上在冷冻层零下4~24度的环境中,蟹肉中的细菌等微生物活性能够得到有效的抑制,反而能够保证大闸蟹保存1~2天都不会变质。
可以。
大闸蟹如果一次太多吃不完可以选择冷冻保存。大闸蟹和海蟹一样,在长途运输时都需先将进行冰冻处理,低温能抑制螃蟹中菌类和寄生虫的活性,同时也能延缓其自身蛋白质的降解,可实现保鲜,对其营养成分和口感几乎没有影响,可以放心食用;
【英文介绍/For English】:
Live crabs cannot be frozen for storage, but cooked crabs can be frozen for storage. After the live hairy crabs are put into the freezing layer, because the temperature is below 0 degrees, the hairy crabs will be frozen to death, and the meat quality will become stale; in addition, after the live hairy crabs are frozen, the crab meat will shrink, so you can eat it next time. At times, the crab meat will dry out and taste bad. The cooked crab meat will not shrink when it is frozen. In addition, in the environment of minus 4~24 degrees in the freezing layer, the activity of bacteria and other microorganisms in the crab meat can be effectively inhibited, which can ensure the preservation of hairy crabs. 1-2 days will not spoil.
