1、海蟹可以放冰箱冷冻保存两到三天。
海蟹的保存方法:
1)鲜活的海蟹可以放入一个干净的容器内,用糙米混合两个打散的鸡蛋,再撒点黑芝麻,用这个混合物倒入容器内,淹没螃蟹的壳,然后用暗色的布把容器口盖上,要能透气但不透光。这样可以延长螃蟹的存活时间,并且能让海蟹的滋味变得更加肥鲜。
2)最好直接在家里养着,将海蟹放在有一点点浅水的盆子里,加透气的盖子,根据储存时间和数量投放少量的小鱼小虾,想吃多少取多少。
3)将海蟹放入冰箱冷冻室冰冻保存,大约可以保存1-3个月。用这种方法处理过的海蟹会保留住鲜味,而且步骤简单。
2、螃蟹分河蟹和海蟹,河蟹是必须吃新鲜的,海蟹就不用,海蟹可以冷冻保存,但一般不要超过三个月以上,这个已经是极限了,冷冻时间过长也会造成脱水变质,建议尽快食用。

  方法一:冰箱保存螃蟹

  螃蟹是属于鲜活水产品,离水后保存时间较短,所购数量能在3天左右的时间吃完的螃蟹保存比较简单:选活力旺盛的螃蟹, 把螃蟹的脚和钳子捆起来,以减少螃蟹体力消耗,然后放在冰箱的冷藏柜,盖上湿毛巾保存即可。每天吃的时候先挑选活力不足的,活力足的螃蟹可继续保存。

    怎么知道螃蟹活力足不足

  区分的办法是:用手轻触螃蟹的眼睛,如果反应不灵敏说明活力不足。

  方法二:塑料桶/盆保存螃蟹

  准备一个30-50厘米高的塑料桶或盆,因为塑料桶/盆内壁光滑不易逃跑。把螃蟹放入其中,然后加水至螃蟹身体的一半高-主要是保湿,不能把大闸蟹全部埋住,如果水太深螃蟹会缺氧窒息而死。桶/盆无须加盖,采用这种方法保存螃蟹,气温不高的时候大闸蟹保存可超过5天。

  方法三:暂养池保存螃蟹

  如果所购螃蟹量多三五天吃不完,就不能用上面的方法储存了,最好的办法是,把自己的浴缸做暂养池,先让出来给螃蟹享受一下了:因为浴缸四壁光滑,螃蟹无法逃跑,然后把螃蟹轻轻倒入浴缸中,注水到刚好埋住螃蟹,如果螃蟹把八足立起来就可以在水面呼吸,并根据储存时间和数量投味少量的小鱼小虾,用这种方法储存螃蟹一般可超过7天或更长,品质好的螃蟹储存成活率可达95%以上。

  特别提醒:如果不是马上吃的话,请千万不要用水洗,不然螃蟹会死。假如室内温度不超过15℃的话就不用放冰箱了。正常情况下可以保存5-7天,不过保存时间太长螃蟹会瘦一些,3天内食用不影响口感。

    螃蟹放进冰箱冷冻保存前,要注意什么呢?

  冷冻螃蟹当然已经不如新鲜的好吃了!但是只要抓住一个小秘诀,就是在冷冻前,先用沸水煮过,放凉,再放进冰箱,等到要烹调时再拿出来料理,肉质会十分鲜美哦!

    死螃蟹放冰箱能存放多长时间?

    这个问题要区别对待:属于河蟹死了是不能吃的;属于海里的螃蟹只要没有发臭,是可以食用的。

    写在最后:通常吃海鲜,海鲜的鲜度很重要,不新鲜的蟹贝类不仅风味差,而且容易引起中毒。所以死的蟹就不要吃了。
