The whole body use of whales

Whales are all treasures and have important economic value. Its huge body provides people with a large number of products such as whale meat and whale oil. The value of a blue whale of about100t is 10000 USD. Whale meat accounts for about half of whale's weight. In addition to grinding into coarse powder as feed or fertilizer field, it can also be processed for human consumption. It is rich in protein and has high nutritional value. Food malls in Norway and Japan serve fresh whale meat and canned whale meat. Japanese food researchers believe that whale meat tastes better than beef and is one of the most delicious foods in the world. Japan also uses whale meat as raw material and processes it into man-made fibers.

Whale fat is an animal oil rich in synthetic fat. It not only contains a lot of glycerol, but also can be used for nitroglycerin and cigarette processing in synthetic explosives, as well as for making soap and refining high-grade lubricating oil. The fatty acid content in whale fat is below 2% at the lowest and about 30% at the highest. The lighter the blubber, the higher the quality. A blue whale weighing 120 tons can get more than 40 tons of oil. This amount of oil is equivalent to lard taken from thousands of fat pigs. After hydrotreating, whale fat can be made into tasteless blocks or edible margarine.

Whale fat has many other uses. It can make candles and oil paints. It is also used in steelmaking and tanning industries. Because the viscosity of whale oil remains unchanged at high temperature, it is used as lubricating oil for some precision instruments. For example, sperm whale oil can be used to extract industrial oil and whale wax oil. Whale wax oil is taken from the head of sperm whales. It has a high melting point and can be used to make cosmetics and candles.

Long Xianxiang has been regarded as a high-grade spice since ancient times, and the price per kilogram ranges from 100 to several hundred dollars. The source of this high-grade spice was once a secret of speculation. In fact, it's just waste accumulated in the stomach of sperm whales after indigestion. Interestingly, such a behemoth will have indigestion, and indigestion in the stomach has become a rare high-grade spice. Long Xianxiang was originally a waxy substance, and its appearance was grayish yellow, dark gray or brownish. When it comes out of the body, it smells strange and unpleasant. When it is dried, it is amber. When it is ignited by fire, the flame is blue and fragrant, with a musk-like taste. This natural perfume varies in size and shape, ranging from tens of grams to 400 kilograms. Because of its wide use and peculiar smell, it is called "floating gold". Its specific gravity is only 0.9, its melting point is about 60℃, and it can be dissolved in alcohol. Long Xianxiang used to be a high-grade raw material for making perfumes and stimulants, and later it was widely used for making vanishing cream, lipstick and other popular cosmetics.

In addition, the whale cortex is soft and the surface is rough. Patterned fur and leather are suitable for making clothes or wallets. Whale fins can be used as umbrellas, bras, bow ties and cigarette cases. Whale ovaries are also the raw material of progesterone, a special drug called progesterone. Whale dung and bone meal are fertilizers rich in ammonia and phosphorus. Bone glue can also be extracted from whale bones as raw materials for processing photographic films. Whale liver is rich in vitamins A and D, and sperm whale liver often weighs 400 kg, and its vitamin A content is equivalent to 100 ton of high-quality cream or 5 million eggs. Whale whiskers and whale teeth can be processed into medical instruments or handicrafts.
