头部有深绿和浅绿物质,腹部也有深绿色物质,发黑,不知道能不能吃?
放狗搜了一下,有说是卵的,有的说是肝脏,也有说叫啥啥龙虾膏,很美味,有知道的吗?

  • 龙虾的大部分消化系统在头部,所以绿色的是未消化完的食物,海藻之类。我一般都是不吃的。不过要是煮熟了吃下去也没事,但不是什么精华就是了。好吃的是虾膏,有些龙虾里面有。煮熟了是红色的。

  • 吃过,没出状况过。 在 maine 龙虾店里吃的时候 waitress 说黑色的是籽,主要存在在身子到尾巴的部位,不太熟的时候是黑绿的,cooked 了会变红。 浅绿的应该只在头部和身子链接的地方,据说是 liver 之类,也可以吃,只要不多吃,比如每天不要超过一个龙虾,呵呵。不过对 shell fish 过敏的人也许吃这部位过敏的危险更高。 其实都挺好吃的,就像吃螃蟹,有哪种浅黄绿的稀的膏,也有金黄色的比较结实的蟹黄。

龙虾头部绿色的东西,究竟能不能吃?

上图中绿色的部分就是传说中的“龙虾膏”,我在网上搜了搜,还挺多人说这个龙虾膏挺好吃。

我住在美国东岸,我们所说的龙虾(别名:波士顿龙虾,缅因龙虾,加拿大龙虾等)其实不是真正意义上的龙虾。龙虾属动物其实是没有大螯的,波士顿龙虾是一种螯龙虾。

上图是一种正宗的龙虾,有长须子但是没有大螯。

拉回来说波士顿龙虾,话说大部分动物的大脑都在眼睛的后方不远处,波士顿龙虾(下文简称为“波龙”)也不例外,但是这个物种(龙虾和螯虾都一样)的大脑非常小,占用的体积微乎其微。

大家看上面这张图中,龙虾眼睛后方那个黄色的小点就是龙虾的大脑(可以这么认为吧),而占据波龙大头的大部分体积的就是那个绿色的东西——胃部。

上图就是百度网友发的生龙虾膏的图片。既然知道了龙虾膏是龙虾的消化腺(英文有个专用词,叫tomalley),那么我们首要搞清楚的就是龙虾一般都吃啥。

美洲螯龙虾以鱼类、其他小型甲壳类及贝类为食,偶尔也会吃海中植物

美洲螯龙虾以鱼类、其他小型甲壳类及贝类为食,偶尔也会吃海中植物

从维基百科的资料来看,波龙生活在水底的礁岩缝隙或者砂砾海底打洞。它们是机会主义者,吃的都是路过的小鱼小虾和贝壳。

这种分子式为C10H17N7O4的毒素产生于海水里的微小藻类,然后被滤食有毒藻类的贝类进一步提纯,最终贝类被波龙吃进了肚子里,龙虾膏也就变成了有毒的龙虾膏。

上文提到了两个有趣的事情。第一点,这篇文章只针对龙虾的消化腺提出警告,尤其是龙虾肝脏和胰脏,就算消化腺有毒,龙虾肉却能无毒;第二点,跟雪卡毒一样,高温烹饪并不能消毒。

PSP中毒的症状是口腔,面部和颈部麻木或者刺痛,肌肉无力,头晕恶心等等。在极端情况下,如果摄入毒素过量,会导致窒息而死亡。症状一般在进食之后2个小时之内会发作,如果感觉不适,请尽快就医。

当然,高浓度的PSP这种情况极其少见,但是微量的毒素还是有可能的。

What's the Green Stuff in Lobster and Can You Eat It?
https://www.allrecipes.com/article/green-stuff-in-lobster/

It's called tomalley and people have some opinions about it. For some, that gooey, green paste is something to avoid — for others, it's a delicacy.

While marine biologists may refer to this green goo as hepatopancreas, in culinary settings you'll most likely hear it referred to as tomalley (taa-ma-lee). It's a part of the lobster's digestive system — it works kind of like a liver and a pancreas combined, and is found in the body cavity.

Tomalley is considered the most flavorful part of the lobster. Its flavor is basically the same as that of a lobster, just amped up a bit. Those who do eat it will consume it with the rest of the lobster meat, or even reserve it to stir into soups and sauces.

Although folks in New England might know tomalley as a delicacy to be enjoyed, its toxicity has been the subject of much debate. In 2008, the Food and Drug Administration (FDA) warned consumers to avoid eating tomalley from lobsters caught in New England waters because it was found to have unusually high levels of toxins that can cause paralytic shellfish poisoning (PSP).

Unlike toxins found in lobster meat — which is safe to eat — any toxins found in the digestive tract are not water soluble, meaning they won't be eliminated when boiled. These unusually high levels of toxins were said to be caused by an algae bloom known as red tide.

All this being said, it is expected that governmental organizations would urge consumers to err on the side of caution. According to WebMD, lobster tomalley doesn't usually contain high levels of PSP toxins, and the FDA has not issued another warning since. If you are going to partake in tomalley, as many New Englanders do, be sure to do so in moderation.
