For a long time, chitin hidden in shrimp heads and crab shells has been considered as garbage and naturally lost. It has not been discovered until recently by scientists and technicians that chitin and its derivatives have been used in agriculture, medicine, food, chemicals, cosmetics, etc. Biotechnology, environmental protection and many other aspects have extremely important and extensive uses. Processing and utilization of waste from aquatic products has significant economic, ecological and social benefits.
First, the use of fish waste to produce fish oil and fish meal fish oil is mainly used to extract cod liver oil, but also can replace mineral oil as leather preparations, or for the manufacture of drugs for the treatment of diabetes, hypertension and other diseases; fish meal is mainly used as high protein feed. Generally, the leftovers processed per ton of fish can produce 30 kilograms of fish oil and more than 200 kilograms of high quality fishmeal.
Second, the fish skin leather leather as an important leather raw material, is gradually being taken seriously. Leather shoes, gloves, purses, wallets and other items made of fish leather are very popular among consumers, and export exchange rates are extremely high.
Third, clam shell processing nacre powder and shell powder nacre powder is widely used in medicine, cosmetics manufacturing; shell powder is an indispensable raw material for feed processing.
Fourth, fish bone bone powder processing bone powder is mainly used as feed additives. The processing method is as follows: the fish bones are put into a pot and boiled for several hours. After the bone's fat is completely cooked, it is removed and dried, and is smashed and sieved.
5. Extracting Protease from Fish Intestine This enzyme is mainly present in the digestive enzymes in fish and acts as a biocatalyst to accelerate chemical reactions. It can be widely used in the manufacture of detergents, remove stains and dirt, and can also be used in the food processing industry. And biological research.
VI. Processing fish with scales Silver fish is an expensive special industrial product extracted from the scales. Its appearance is sterling silver white and has a high degree of luster. It is used as a pharmaceutical raw material and biochemical agent, especially in pearl decoration industry and The paint industry has a wide range of uses. Treated fish scales can also be used to process fishmeal. The economic benefits are considerable.
Seven, shrimp head crab shell processing Chitin Chitin is very widely used, made of drugs have enhanced immune function, made of surgical sutures without stitches, but also as a waste water treatment agent, food preservatives, cigarette adhesives, plants Growth regulators and so on.
