How to buy fresh shrimp? How to choose fresh shrimp

The identification of fresh shrimp is mainly based on sensory inspection of the connection between its head and body, shell and meat, as well as the hardness and skin color of the shrimp body.

Shrimp: Fresh shrimp of high quality, the head and body are closely connected, the shell and the shrimp meat are tightly integrated, the shrimp body is hard and elastic, the sides of the body and abdomen are white, and the back is cyan (the whole body of the male shrimp is egg yolk), shiny. If the head and body connection is loose, the shell is separated from the meat, the shrimp body is soft and loses elasticity, the body color turns yellow (male shrimp becomes dark yellow), and loses its luster, and the black waist appears between the body segments of the shrimp is the quality shrimp.

Shrimp that turn around, have a soft body like mud, have a shell that falls off, and have a black and purple body color are of very poor quality.

White shrimp: Fresh white shrimp of high quality, white and transparent in color, with small blue or red spots. The shrimp body is intact, hard and elastic.

If the shrimp body turns yellow, the spots increase, and the body is soft and loses its elasticity, it is defective. The quality is very poor, and the shrimp body is dark yellow or pink. Other changes are the same as for prawns.

Green shrimp: also known as river shrimp and giant river prawn. The high-quality green shrimp has a greenish and shiny body surface.

The shrimp body is intact, hard and elastic. The appearance of the inferior green shrimp turns blue-white, and the shrimp body is soft and loses its elasticity. Those with serious poor quality have a pinkish white appearance, turn around, their bodies are soft as mud, their shells fall off, and they have peculiar smells.

1) Look at the color. Fresh shrimp have shiny skins, river shrimp are blue-green, and shrimp are egg-yolk (male) or blue-white (female). Stale shrimp with dark shells and a reddish or grayish-purple primary color.

2) Look at the shape. The head and tail of fresh shrimp are intact, the head and tail are closely connected to the body, and the shrimp body is relatively stiff and has a certain degree of curvature. Stale shrimp are loosely connected to the head and body, shell and flesh, and the head and tail are easy to fall off or separate, and cannot maintain their original curvature.

3) Look at the quality of the meat. Fresh shrimp with firm, tender flesh that feels hard and elastic to the touch. Stale shrimp with fluffy flesh and poor elasticity.

4) Smell the smell. Fresh shrimp have a normal smell and no peculiar smell. If there is a peculiar smell, it is spoiled shrimp. In addition, after the shrimp are cooked, the tail wing must be fanned out due to the strong contraction of the tail muscles.

Introduction: Fresh and high-quality frozen shrimp should be colorless and transparent, full and elastic to the touch, while those that look large and red should be treated with caution. Shrimp is nutritious and delicious to eat, especially for families with children, often get some shrimp for children to eat, which can supplement a lot of nutrients.

But when you buy shrimp in the supermarket or vegetable market, you must pay attention to the quality of the shrimp. So how can you buy high-quality and healthy shrimp? Let's take a look at how to choose fresh shrimp, teach you the purchase skills, and eat shrimp with confidence.

1. No peculiar smell

Fresh shrimp have a normal fishy smell, if there is a peculiar smell, it means that the shrimp have gone bad.

2. The meat shells are tightly connected

Fresh. The shell is very tightly glued to the flesh, and when you peel the shell by hand, the flesh is sticky to your hands, and it takes a little effort to peel off the shell. The intestinal tissue of fresh shrimp and the shrimp flesh are also sticky tightly, and if there is a loosening phenomenon, it indicates that the shrimp is not fresh.

Check the degree of connection between the thoracic joint and the abdominal or terrestrial joint. At the end of the thoracic segment of the shrimp body there are stomach organs called "shrimp brains" and liver. After the death of the shrimp body, it is easy to perish and decompose, and affects the tissues of the cephalothorax and ventral segments, so that the internode connection becomes relaxed.

3. Dry body surface

The appearance of the live shrimp is clean, and it feels dry when touched by hand. However, when the shrimp body is about to deteriorate, the granular cells that secrete mucus under the carapace disintegrate, and a large amount of mucus seeps into the body surface, making it slippery to the touch. If the shell sticks to the hand, it means that the shrimp have gone bad. Slippery.

4. Bright color

In the dermis under the carapace of the shrimp body, there are various pigment cells, which contain carotene-based chromogenesis, which are often combined with proteins in various ways. When the shrimp body deteriorates and decomposes, it is separated from the protein and produces astaxanthin, which makes the shrimp body red.

Depending on the species of shrimp, there is a slight difference in color. Fresh prawns, Roche shrimp and grass shrimp are blue, sea-caught prawns are pink, and bamboo shrimp and Jiwei shrimp have black and white patterns with a slight pink. If the shrimp has black hair, it is not a fresh shrimp, and the whole shrimp is relatively black and not bright, which means that it has deteriorated.

5. Test the flexion force

The head and tail of fresh shrimp are intact, the head and tail are closely connected to the body, and the shrimp body is relatively straight, with a certain elasticity and curvature. Stale shrimp are loosely connected to the head and body, shell and flesh, and the head and tail are easy to fall off or separate, and cannot maintain their original curvature.

When the shrimp body is in the stage of zombie stiffness, the internal tissues are intact, the cells are filled with water, swelling and elastic, so it can maintain the inherent state of stretching or curling when it dies, even if it is changed by external force, the first external force stops, and it still returns to its original posture. When the shrimp body is autolyzed, the tissue becomes soft and loses this stretching force.

Reminder: In addition, pay attention to safety and hygiene when eating shrimp. Shrimp may contain bacteria and parasites that are resistant to low temperatures, and even dipping them in vinegar and mustard cannot completely kill them, so it is recommended to eat them after they are cooked thoroughly. Shrimp that cannot be eaten should be refrigerated and heated before being eaten again.
