Is the black line in the shrimp back dirty? Seven Truths Must Be Seen Before Eating Shrimp

Summer is a dry season.

Someone faltered and asked Dr. Clove a question:

What is shrimp thread? The crayfish I ate yesterday did not go to the shrimp line. Did I eat Shi?

Considering that everyone eats shrimps all the year round, Dr. Clove felt it necessary to make clear all kinds of questions about shrimps.

Is the shrimp filthy?

Truth: Shrimp thread is the intestinal tract of shrimp. If you mind, remove it.

Shrimp lines are usually cyan and black, and there is what remains in the shrimp intestinal tract (you know). Theoretically, it is a little dirty, so it is generally recommended to remove it before eating.

If you’ve had it before… That’s fine.

After cooking (cooked), the bacteria in the shrimp line will be killed by high temperature, which is safe, but the taste may be worse.

There are heavy metals in shrimp heads?

Truth: The content of heavy metals in shrimp heads is indeed higher than that in shrimp meat, but there is no need to be afraid of regular cultivation.

Heavy metals in shrimps mainly come from water and feed. Generally speaking, the content in viscera (shrimp head) and shrimp shell will be higher.

However, don’t worry too much. If the water quality and feed are too poor, shrimps cannot survive, so regular farming is still guaranteed. Moreover, the regulatory authorities will regularly conduct spot checks on various aquatic products.

As for the black color of some shrimp heads… it is because of feed problems, or tyrosinase produces some melanin, which has nothing to do with heavy metals.

If you really have doubts, then concentrate on eating shrimp meat, because there is less meat on your head anyway.

Is there a parasite in the shrimp?

Truth: There is a risk of parasites, and cooking can ensure safety.

Recently, the shrimp head parasite widely spread on the Internet is actually the vas deferens of shrimps, and the shrimps themselves feel a little wronged.

Although the video is a rumor, there is indeed a risk of parasites in aquatic products.

The best way to deal with it is to cook it.

Many areas in the south like to eat drunk shrimp. Although it tastes delicious, from a safety point of view, Dr. Clove advises everyone not to eat it as much as possible.

Can shrimp skin supplement calcium?

Truth: Calcium content is quite high, but it is not easy to absorb and is not recommended.

We often say that shrimps supplement calcium, mainly referring to the shrimps in marine shrimps.

It is a well-known [calcium supplement food], with a calcium content of 991 mg per 100 g, much worse than milk (100 mg/100 g).

But! Dr. Clove does not recommend people to eat shrimps to supplement calcium:

    Shrimp skin has more calcium but more salt, 100 g contains 5057 mg sodium; The usage is too low, usually cooking also use a few grams, it is better to drink milk; Shrimp skin is difficult to chew and digest, and it is difficult to decompose and absorb after eating.

If you eat shrimps to supplement calcium, you might as well drink a cup of milk and eat some tofu and vegetables.

What, do you want to eat shrimp shells?

…… Don’t you prick your mouth?

Shrimp and fruit are compatible?

Truth: What about the delicious pineapple shrimp balls?

Legend has it in the Jianghu that vitamin C in shrimps and fruits can produce arsenic, a highly toxic substance, so fresh river seafood such as fruits and shrimps and crabs cannot be eaten together.

Rumor mongers must not know that lobster has a classic way to eat, which is to squeeze lemon juice after steaming…

Shrimp does not contain much inorganic arsenic, and vitamin C does not have that much ability. They meet… what has nothing to do, so eat at ease.

Which is better, shrimp or freshwater shrimp?

Truth: Each has its own advantages and disadvantages. Listen to the wallet.

    Nutritionally speaking, shrimp has higher protein content and richer unsaturated fatty acids, such as DHA and EPA. In terms of cooking and flavor, the shrimp meat is large but has heavy fishy smell, and the freshwater shrimp meat is more elastic and tastes better. In terms of price, shrimps are usually more expensive than river shrimps.

Which one is better? It depends on your own taste and the thickness of your wallet.

Nutritional Characteristics of Shrimp

Truth: High protein and low fat, pay attention to practice and quantity.

Shrimp, as a kind of aquatic products, whether shrimp or freshwater shrimp, belongs to high protein and low fat food and is a good source of protein.

Dr. Clove gives you a good reason to eat crayfish, prawn, river prawn and lobster:

< < Dietary Guidelines for Chinese Residents 2016 > > > It is recommended that the weekly intake of aquatic products should reach 280 ~ 525 g.

Although the tastes of braised oil, spicy, strange, mashed garlic, chili sauce, thirteen spices and so on are very delicious, the most recommended by Dr. Clove is white burnt shrimp (steamed shrimp), because:

    Nutrition loss is small and calorie is low. The delicate taste of shrimp is well preserved. Can quickly find out whether the ingredients are fresh.
