海蟹死了能吃吗

海蟹死了还能吃吗？有时候海蟹是从外面买的，回家就死了。一般海鲜只有活着才好吃。那么这只海蟹死了还能吃吗？有些人可能认为海蟹死后可以吃，扔掉太浪费了。其实死海蟹有毒，不能吃。让我们一起来看看。

海蟹死了能吃吗

死海蟹含毒素

中医认为，海蟹性咸，性寒，所以经常手脚冻僵的人(尤其是女性)，身体虚弱或体弱的人不宜多吃。或者可以在做菜的时候多加点姜、葱、蒜等调料，这样这些辣的食材就能中和海蟹的凉意。或者吃海蟹后喝一杯黄糖姜茶暖胃，去腥散寒。此外，乡亲们认为吃螃蟹前后不宜吃柿子等凉性水果，其实只是为了避免吃太多凉性食物，会造成身体虚弱和不适。

海蟹是一种免疫力很强的食腐动物。它吃了很多细菌和病毒，但都被海蟹的免疫力所抑制。一旦海蟹死了，甚至还没死，它就刚刚死去，细菌和病毒会繁殖繁殖一些生物毒素。因为海蟹喜欢吃动物尸体等腐烂的物质，所以它们的胃肠道里经常携带致病菌和有毒物质。一旦死亡，这些细菌就会大量繁殖。此外，海蟹还含有较多的组氨酸，容易分解，在脱羧酶的作用下能产生组胺和组胺样物质。特别是螃蟹死亡时，组氨酸分解更快，螃蟹死亡时间越长，体内积累的组氨酸越多，当组胺积累到一定量时，就会引起中毒。你所要做的就是不要吃半死不活的海蟹。

如果人们食用这种海蟹，会严重引起脱水、电解质紊乱、惊厥，甚至休克、昏迷、败血症等。常见表现为恶心、呕吐、腹痛、腹泻。

有人可能会问，海蟹煮熟后，不是还没死吗？你不是还吃死螃蟹吗？海蟹自然死亡为什么不能吃？

在这种情况下，是有区别的。如果海蟹自然死亡，体内的毒素会翻倍，这些毒素也会分解蟹肉。对于自己做的海蟹来说，体内的毒素早已排出，高温过后，这些都有效的阻止了细菌的传播，起到了更好的杀菌作用。

而且水烧开后，再煮20分钟，这样可以杀死蟹肉中的病菌。海蟹味道鲜美，但如果是因为储存不当而死亡的海蟹，为了自己和家人的健康，还是直接送进垃圾桶比较好。

海蟹虽然营养价值丰富，但吃起来有很多讲究，但死了一定不能吃。看了边肖的介绍，你知道更多了吗？如果你是螃蟹爱好者，要记住吃海蟹的注意事项，以免影响身体健康。

如何挑选海蟹

海蟹被抓后，体内的乳酸往往会因为想要挣脱而增加，会导致体内的细菌迅速繁殖，在海蟹死亡后扩散到蟹肉上。细菌可以分解海蟹体内的氨基酸，进而产生一种有害物质“组胺”，引起过敏性食物中毒。另一种可能的物质是“类组胺”，会引起呕吐、腹痛和腹泻，所以我们在选择时要注意。

买海蟹一定要买活的，因为死蟹含有一定的毒性，对我们的健康非常有害。因为海蟹死亡时，海蟹体内的组氨酸会分解产生有毒的组胺，海蟹产生的毒素会随着死亡时间的延长而增加。因此，你必须选择活螃蟹。

挑选时，可以用手指轻轻按压蟹眼的壳面。如果螃蟹的眼睛立即移动，就意味着它充满活力。你也可以把手指放在蟹爪之间。如果蟹爪强，说明海蟹生命力强。还有，离开水的螃蟹会吐出泡沫，这是活螃蟹，可以放心购买。

海蟹很容易区分雌雄。我们把海蟹调头，三角形的肚子是雄性，圆形的肚子是雌性。

然而，大师可以通过看他的腿来判断。雌蟹的爪子上有一团灰黑色的绒毛，但其他地方没有。雄性的八条腿也有像刷子一样排列的细毛。

海蟹吃不完如何保存

保持在不动、低温、避光、保湿的原则下。室温高的时候，尤其是9月份，螃蟹要扎紧，有香蒲的要扎紧。外包装浸湿，以免滴水，放入冰箱冷藏室。这不是全部。用湿毛巾将绑好的螃蟹盖上，储存温度控制在5-10。

1.把大闸蟹放在冰箱里。把大闸蟹和大闸蟹3354的脚绑起来，减少大闸蟹的体力消耗，然后放在冰箱的冷冻室里，用湿毛巾盖上，保存七天以上。

2.把阳澄湖大闸蟹养在塑料桶/盆里。放大闸蟹进去。——不能堆叠；然后加水到大闸蟹一半的高度。——主要是保湿。不能把大闸蟹都埋了，因为不太可能配备增氧设备。如果水太深，螃蟹会因为缺氧窒息而死。盆/桶不用盖，大闸蟹要每天检查，活力不足的大闸蟹要及时食用。阳澄湖大闸蟹在气温不高的时候可以保存5天以上。

可见海蟹死了是不能吃的，也要吃煮熟的海蟹，否则对健康有害。
