What is the “black vein” that shrimp have and why is it important to remove it – Enseñame de Ciencia

Shrimp or karidos, a type of marine crustacean or freshwater crustacean, also known as prawns, prawns or brisket, is a food source largely used by humans.

In gastronomy, they are known as seafood and represent a source of food, protein and nutrients. They are a highly demanded product by diners, especially in December and Lent (the liturgical time in the Christian calendar for the spiritual preparation for Easter).

Seafood is a non-perishable product that quickly decomposes, so it is recommended to eat it fresh or keep it in the refrigerator all the time until it is eaten.

However, there are other dangers surrounding them, most notably shrimp when eaten in large quantities. Although this shellfish contains very beneficial stable fats, its high consumption can generate cholesterol and cardiovascular disease.

In addition, there is an inherent risk of poisoning by eating contaminated products or the presence of toxins. But there is another reason why eating shrimp is harmful.

These crustaceans are widespread in the world, as they are found in both fresh and salt water and are known as “sea crickets”. They are named this way, because of their omnivorous eating habits, that is, they feed on rubbish from the sea, just as cockroaches feed on terrestrial rubbish.

A suitable trait for people who consume a large amount of seafood and we will tell you why below.

Shrimp are delicious in cocktails, breaded, on their own for a snack, in gravy, or in any of their presentations. However, it is important to ensure that the product we are about to consume has been prepared with the necessary hygiene in mind, especially since it is a very delicate food.

By this we mean that we make sure that the black line on the top of the oyster is removed, as it can be a cause of disease.

What is black vein in shrimp and why is it important to remove it?

This thin green to black line that the shrimp has is the intestine of the animal and in this narrow space is stored the feces of the food it has consumed in life.

During its life cycle, shrimp feed on algae, small animals, carrion, and debris from other dead fish; Foods that may contain parasites and are harmful to health.

The risk is increased when this type of food is eaten raw (in ceviche), as it is believed that enough lemon juice is enough to cook the shellfish.

In fact, lemon juice carries out a process called protein denaturation and changes the structure of the protein when it comes into contact with acid or heat, changing its physical and chemical properties.

However, by not exposing the product to high temperatures, potential pathogens and parasites are not eliminated.

Additionally, the idea of ​​eating poop isn’t something diners like. So, now you know, these are the important reasons to remove the black line (or vein) from shrimp.
