1. What are the benefits and nutritional value of sea urchins? Where is the best place to get them?

In recent years, consumers in Japan, France, the United States, Germany, Hong Kong and Macao have all regarded sea urchins as high-end, precious and high-quality health foods. The Japanese, in particular, not only like to eat fresh sea urchin roe, but also like to eat caviar made from sea urchins, which is named Yundan.

Sea urchin roe is not only delicious, but also has high nutritional value. Every 100 grams of fresh sea urchin roe contains 41 grams of protein, 32.7 grams of fat, vitamin A, D, various amino acids, phosphorus, iron, calcium and other nutrients. Sea urchin can also be produced and processed into salted sea urchin, alcohol sea urchin, chilled sea urchin, sea urchin sauce and steamed sea urchin canned food.

Sea urchin also has medicinal functions. It is salty and flat in nature. It has the functions of relieving acid and relieving pain, softening and dispersing nodules, removing blood stasis and reducing swelling, clearing away heat and inflammation, strengthening the spleen and kidney, relaxing muscles and promoting blood circulation. It has the functions of nourishing yin and tonifying yang, and is mainly used to treat cervical lymphadenopathy. The roe of sea urchin contains a high amount of fatty acids, which is a good medicine for preventing cardiovascular diseases, reducing the content of triglycerides and cholesterol in the human body, anti-coagulation and preventing thrombosis, etc. Eating food made from sea urchin roe can improve the body's immunity, calm the nerves, replenish blood and promote sexual function. Sea urchin roe is also extremely rich in hormones, so eating it has the functions of nourishing yin and tonifying the kidney, and nourishing the skin. In addition, the high protein contained in sea urchin roe is easily absorbed by the human body, and its taste is particularly delicious, which promotes saliva secretion, stimulates appetite, and has a good tonic effect.

For patients with gastritis and duodenal ulcer, otitis media, cervical lymphadenopathy, middle thoracic ribs, and paronychia, grind the ash of sea urchin shells into powder and take it or apply it in appropriate amount. For patients with otitis media, grind the thorns of sea urchins with white wax and blow it into the ears. For patients with phlegm accumulation and chest and rib pain, remove the thorns of sea urchin shells, use 3-6 grams, decoct in water; for the treatment of cervical lymphadenopathy, use 6 grams of sea urchin shells, 15 grams of Prunella vulgaris, and 9 grams of Fritillaria, decoct in water. Sea urchin shells are dried and crushed, and they are still very good fertilizers. The fertilizer effect of 500 grams of shell powder is equivalent to 500 grams of bean cakes.

There are many ways to eat sea urchins. Whether it is fresh sea urchin roe (yellow) or any processed series of varieties, it can be used for steaming, frying, cold dishes or cooking into soup. For example, frying sea urchin roe with meat, asparagus and eggs will become a delicious and superior dish; and using sea urchin roe soup to soak noodles, without adding any seasoning, the taste is more delicious than chicken noodle soup. If sea urchin roe is used in hot pot, the flavor is even more unique. More high-end ways of eating include sea urchin stewed with abalone and sea urchin stewed with snow clam and many other precious dishes. In Guangzhou and Xiamen restaurants, most sea urchins are steamed. The method is: first use a saw to saw a cut on the top of the sea urchin shell, then inject an appropriate amount of egg paste from the cut, mix it with the sea urchin roe in the shell, and steam it whole. It can be said to be authentic and original. This way of eating is suitable for all ages.

In recent years, with the booming development of my country's coastal aquaculture industry, sea urchin aquaculture has also taken the lead. Through scientific stocking, the harvest of sea urchins is no longer restricted by climate and seasons, and they are produced all year round in Fujian, Guangdong, and Taiwan. Therefore, fresh sea urchins have become increasingly popular in coastal areas, adding a treat to tourists.

2. How to tell if sea urchins are poisonous?

Sea urchins are divided into poisonous and non-toxic. Some sea urchins contain toxins on their spines.

How to identify poisonous sea urchins: Poisonous sea urchins look much prettier than non-poisonous ones, and their colors may be brighter.

3. Briefly describe the edible characteristics of sea urchins

Introduction

Sea urchins are invertebrates with a fine hard shell covered with many thorns called spines. Sea urchins can be spherical, heart-shaped or pancake-shaped. They live in oceans around the world, with the largest number of species in the Indian Ocean and the western Pacific Ocean.

How to choose sea urchin

Unlike clams, sea urchins are not fresh and alive just by tapping their shells. The main way to select sea urchins is to look and touch them.

1. Look carefully, the spines of fresh sea urchins will move. The larger the movement, the fresher it is.

2. Touching The vendors selling sea urchins in the market usually prepare a small screwdriver. Use the tip of the screwdriver to touch the mouth of the sea urchin (the mouth is located in the center of the abdomen of the sea urchin). When the live sea urchin is stimulated, its mouth will shrink rapidly.

Taboos on eating sea urchin

Not all sea urchins are edible, and many species are poisonous. These sea urchins look much prettier than non-toxic ones. For example, the thorn-ringed sea urchins that grow among the coral reefs of the South China Sea have black and white stripes on their thick spines and yellow thin spines. The spines of young thorn-ringed sea urchins have white and green ribbons that sparkle, and a barb grows at the tip of the thin spines. Once it pierces the skin, the venom will be injected into the human body, and the thin spines will break off in the flesh, causing local redness, swelling and pain on the skin. Some people even have symptoms of poisoning such as rapid heartbeat and whole-body spasms.

4. What should I do if my dad is stung by a black sea urchin in Cambodia?

The method is correct. Actually, there is no good way. Just tap and soften the sea urchin spines. Generally, the pain will disappear in a few hours; but the pain is unforgettable! If you still feel pain after such a long time, it is recommended that you apply olive oil or something on the surface, and then use the big plastic head of a big screwdriver to slowly tap the surface where you were stung to accelerate the softening of the spines. . . Don't worry, it will just hurt a little, but it is not life-threatening. I also learned this after being stung. In the future, I must buy professional diving shoes and wear them when I go into the water. It is foolproof:)

5. Can I catch sea urchins directly? When I was traveling, I saw some in the cracks of rocks in the shallows. Are the spines poisonous?

That depends on what kind of sea urchin it is. Not all sea urchins are edible, and many species are poisonous. These sea urchins look much prettier than non-toxic ones. For example, the spiny sea urchins that grow among the coral reefs of the South China Sea have black and white stripes on their thick spines, and yellow thin spines. The spines of young spiny sea urchins have white and green ribbons that sparkle, and a barb grows at the tip of the thin spines. Once it pierces the skin, the venom will be injected into the human body, and the thin spines will break in the flesh, causing local redness, swelling and pain on the skin. Some even have symptoms of poisoning such as accelerated heartbeat and whole body spasms. So if you don't know if it's poisonous, don't catch it directly!
