Detailed classification of uses:

1. Nutrition research

① Fly maggots are rich in protein,

Therefore, protein can be extracted from fly maggots and used in food industry, fermentation industry, rubber industry and so on.

② The amino acid composition of fly maggots is reasonable, which can be used to prepare hydrolyzed proteins and amino acids. Amino acids can be used as drugs to treat some diseases caused by amino acid deficiency, and can also be processed into health food, food fortifier and cosmetics.

③ Fly maggots can be directly processed into protein active powder, which has the functions of anti-fatigue, anti-radiation, delaying aging, protecting liver and enhancing immunity, and is an ideal health care product;

④ Chitin can be extracted from the epidermis and pupa shell of fly maggots. Chitin is a natural bioactive substance containing nitrogen polysaccharide, which is widely used in many high-tech fields such as industry, medicine, food, daily chemical, national defense, environmental protection, agriculture and so on. Its development and utilization have been paid more and more attention by scientific, medical and business circles at home and abroad.

⑤ New drugs can be developed by using fly maggots. Housefly has a unique immune function, and its body contains an "antibacterial active protein", which has a strong bactericidal effect, and the concentration of this active protein is enough to kill invading bacteria as long as one ten thousandth. At the same time, its hemolymph contains lectin with anticancer effect. In addition, the fly maggot also contains an Alcaligenes faecalis, which can inhibit various germs of skin abscess and promote the formation of epidermis and the healing of sores. In addition, houseflies also contain 2%-4% phospholipids, which have the functions of protecting cell membrane, reducing blood lipid and preventing cardiovascular diseases, so fly maggots have broad prospects in medical development;

⑥ Fly maggots and their breeding wastes can be developed into compound fertilizers to promote crop growth and insecticides or disease-resistant preparations with insect resistance and disease resistance.

2. flies can be used as medicine

Flies, which are repulsed by human beings, begin to become resource insects beneficial to human beings. Recently, experts from Tianjin Nankai University and Tianjin University joined hands with Tuanbowa Development Company of Dagang Oilfield Group to tackle key problems, and completed the production of high-quality chitin, chitosan and its derivatives from fly maggots, which are widely used in medicine, food, cosmetics, environmental protection and other fields. The research results have applied for two patents and passed the appraisal.

Fly is a common name. The flies raised for scientific research are just one kind of flies family, and the scientific name is "housefly". The four growth stages of "egg, maggot, pupa and fly" are strictly disinfected during the feeding process. The difference between flies raised artificially and those seen everyday is that they do not carry any germs and are called "engineering flies" or "resource flies" by researchers.

According to reports, researchers mainly extract chitin and chitosan needed by human beings from fly maggots. The pulp crushed by maggots can separate "antibacterial peptides" with strong bactericidal effect. Compared with the current antibiotics, it is a pure natural product and is not easy to produce drug resistance. Maggot oil can be used for cosmetics and health care. Maggot plasma protein has a good amino acid balance, which is suitable for human absorption and is a high-quality health care product.

3. Used in feed

Using wheat bran, rice bran, pig manure, broken bones and sugar as raw materials, fly maggots can be cultivated. The cultured live fly maggots can be directly used to feed chickens, ducks and other poultry; The protein content of the processed fly maggot powder is as high as 68%, which can be used for pig raising and aquaculture.

Edible fly maggot

The fly maggot immune active substance developed by Dr. Cao Xiaohong from College of Food Science and Bioengineering of Tianjin University of Science and Technology will be used as a food additive, which can improve human immunity and disease resistance.

5. Comprehensive utilization

There are two ways to use fly maggots. The first way is to directly use living organisms: collect maggots and feed them directly to economic animals. Because EM effective microorganisms are used in the culture, the cultured maggots basically have no harmful bacteria and can be fed directly without disinfection. Poultry animals can only feed 5- 10% of the total feed, and supplement some common feed to meet the nutritional needs of poultry. If the feeding amount of fly maggots to poultry exceeds 10%, the protein content of fly maggots is too high, which will cause indigestion and diarrhea in poultry; Feed aquatic animals with 100% fresh fly maggots; Animal husbandry and special animals are generally 2%. The processing method of fly maggot powder is that the collected clean fly maggots are scalded with boiling water, and the fly maggots will die immediately, and then dried and crushed.
