Squid is a marine animal of the family Loliginidae, cephalopod class. In America, known as the squid Loligo spp, while in squid English.
In Indonesia, the squid is known by several terms, as enus, pine, or sepia Sontonga interest. These marine animals are generally caught at night with lights like a drawer petromaks tool. Generally liked the light at night. Crowds of squid can be caught with a trap, plaice, gill nets, seine nets, shrimp trawls, tuna or squid sero.cumi trailer
Squid is a type of marine animal that is of interest to the public, especially fans of seafood and Chinese cuisine. The squid market is generally sold in two main forms, fresh and dried salted.
CHEMICAL CONTENT
Given the nutritional value, the squid is exceptional nutrient content because of the high protein content, 17.9 g/100 g of fresh squid. squid meat has advantages over other seafood, spineless to say, easy to digest, taste and aroma, and contain all kinds of essential amino acids necessary for the body. The dominant essential amino acids leucine, lysine and phenylalanine. Although the levels of non-essential amino acids is mainly glutamic acid and aspartic acid. These two amino acids contribute significantly to the emergence of a sense of delicious and tasty. Therefore, of course, it tastes salty squid, then the treatment does not need to add flavorings (such as monosodium glutamate MSG =).
Squid also contains various minerals, micro and macro very high. content of minerals in the squid is very varied, although one of the same species. This variation depends on the status of “environment in which to live, the size and age. Important minerals in the squid are sodium, potassium, phosphorus, calcium, magnesium and selenium. In richer in protein, the squid is also a good source of vitamins such as vitamin B1 (thiamin), B2 (riboflavin), vitamin B12, niacin, folic acid and fat soluble vitamins (A, D, E, K).
Squid also contains TMAO (oxide Trimethyl Amin), which is quite high. The high TMAO gives flavor to the flesh of squid. squid meat contains too much nitrogen, which causes monoamine squid has a sweet taste. Relatively high sulfur content in Squid Squid, because even odor when considered as a boiling point of cooking.
Sepia liquids are alkaloids, which are preferred by predators, especially fish. This liquid dark grains that contain melanin or black pigment. Melanin is a natural melanoprotein containing 10-15 percent protein. This melanin binds proteins via sulfur containing amino acids, namely cysteine.
Ussage
1. Anti cancer. Besides delicious, squid, rich in nutrients. There are proteins, various minerals and vitamins. Its liquid ink is used to fight tumors.
2. Supporting the growth of bones. part of phosphorus and calcium for good bone growth, it is important for growing children.
3. Preventing osteoporosis. Phosphorus and calcium is also useful for preventing osteoporosis in the elderly.
4. Reduce cholesterol. fatty meat squid belong to the omega-3 polyunsaturated fatty acids can lower cholesterol in the blood.
5. CELL SWITCH white blood. Based on research conducted by Hiroki University in Japan, squid ink and cuttlefish have much utility, which can activate the white blood cells to fight tumors.
6. SKIN HEALING stained and pitted. Usually, patients with smallpox, the skin becomes stained and pitted. This can be treated using squid that has been dried, crushed and filtered, then used as a powder before sleeping.
WARNING eat squid
fat in the flesh of the squid is relatively low at 7.5 per 100 grams, each consisting of 1.9 g saturated fat, 2.7 grams of saturated fat are not uncommon, and 2 1 g polyunsaturated fatty acids.
However, excessive consumption of squid should be avoided because of high levels of bad cholesterol, which rose to 260 mg/100 g of substance. In the group of sea fish, the rate of cholesterol in squid, shrimp, lobsters and crabs is high. However, the rate of cholesterol in fish products is still relatively low compared with egg yolk, liver, viscera and brain of cattle.
The important thing to remember about cholesterol is that we must prevent the nature of phobias. However good cholesterol in dire need of our body, good for cell growth (including brain cells) and synthesis of sex hormones and vitamin D.
In humans, cholesterol can be synthesized in the body, particularly in the liver, cortex of adrenal glands, skin, intestine, testis, stomach, muscles, fat and brain. About 17 percent of the dry weight of the brain is composed of cholesterol. Without cholesterol, the brain structure can not be trained to perfection.
As directed by the National Heart, Lung, and Blood Institute (NHLBI), the total cholesterol is good for the human body is less than 200 mg / dl, HDL above 35 mg / dl, LDL below 130 mg / dl and triglycerides below 250 mg / dl. Cholesterol levels above 200 mg / dL may pose a threat to many diseases such as atherosclerosis (clogged arteries), stroke and coronary.
Although regarded as dangerous, cholesterol is necessary for the body. The average person takes 1,100 milligrams of cholesterol per day to maintain cell walls and other physiological functions. 25-40 percent of this amount (200-300 mg) are normally derived from food and the rest is synthesized by the body.
Therefore, the consumption of cholesterol within normal limits, ie not more than 300 mg per day are needed. So do not worry about cholesterol in squid. Because if you avoid the squid, then lose the benefits of other nutrients for healthy body is very broad.
The uniqueness of the squid
A squid can escape predators quickly through the muscle decreases rapidly. If the motion is not fast enough, dense and dark cloud of ink to be expelled from the body, so that the enemy was surprised a moment. Panic is the enemy long enough for the squid to escape immediately.
In addition, the squid also has a protection system by changing the color of the body quickly, sometimes blue, white, red or brown. This color is due to elastic kromatofor bag containing pigment of red or yellow.
pigment cells, which is surrounded by the connection of elastic muscle cells can contract quickly so that the pigment cells are large and cause the colors more clearly. This mechanism has enabled Squid can change color rapidly when a stimulus from outside. This system of color change is also used squid as a means of communication.
In this sepia was not well known, particularly in the catering sector. Sepia is often not removed and left in the flesh of squid. However, some countries, like Italy, were as a spice for cooking pasta squid ink. In Japan, the sepia bag (sepio melanin) that is black is used to maintain and improve the taste of salted squid.
If you want, no need to remove the squid ink, but can be consumed. Nothing to worry about the substance of thick ink. Some people even consider the substance of the ink is important to enhance the flavor.
