Description

Preparation method of fly maggot freeze-dried powder for health care eating
Technical Field
The invention relates to the field of biological health products, in particular to a preparation method of maggot freeze-dried powder for health care eating.
Background
The fly maggot powder is a high-quality protein resource, contains 55-65% of crude protein and 2.6-12% of fat, and is similar to or slightly higher than fish meal and meat and bone meal. The fly maggot has comprehensive nutrient components and contains 17 amino acids required by animals. The total amount of essential amino acids in fly maggot and its dry powder is 44.09% and 43.83%, respectively, the methionine content is similar to that of fish meal, and the cystine content is low. The fly maggot powder contains chitin, antibacterial peptide and other immunity enhancing substances, and can improve animal immunity. Also contains various trace elements such as iron, zinc, manganese, phosphorus, cobalt, chromium, nickel, boron, potassium, calcium, magnesium, copper, selenium, germanium, etc. A large number of tests and production practices show that the fly maggots are excellent animal protein feed for replacing fish meal.
The application of the fly maggot powder in the aspect of biological feed is more and more extensive, but the application is only described by artificial eating, the national does not set the food safety standard aiming at the fly maggot powder, the fly maggot powder can be found to have a good health care effect on human bodies according to the nutrient components of the fly maggot powder, but the fly maggot is a organism which is very easy to breed bacteria, the contents of heavy metals, coliform bacteria and other pathogenic bacteria of the fly maggot powder are detected to be seriously over standard, and the problems are difficult to solve even the fly maggot powder is prepared, so that the fly maggot powder which is circulated and can be eaten artificially is hardly on the market.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects of the background art, the invention discloses a preparation method of maggot freeze-dried powder for health care eating, which prepares fresh and alive maggots into powder by a unique sterilization preparation process, keeps the nutritive value of the maggots and strictly controls the content of heavy metal and pathogenic bacteria in the maggots at an edible level.
The technical scheme is as follows: the preparation method of the maggot freeze-dried powder for health care eating comprises the following steps:
s1, selecting fresh and alive fly maggots, removing impurities, and washing;
s2, clearing the bowels with maggots;
s3, soaking and disinfecting with a silver ion hydrogen peroxide disinfectant and a sodium hypochlorite disinfectant, rinsing with purified water for multiple times to remove dead maggots and inferior maggots;
s4, immediately freezing at-70 ℃ or below for more than 12h, and then putting the maggots into a freeze dryer for freeze-drying at-70 ℃ or below, wherein the step needs to be immediately performed in consideration of extremely high deterioration speed of the maggots at normal temperature;
s5, sterilizing and disinfecting for 8-10 minutes at 90-100 ℃;
and S6, grinding into dry powder.
Further, in S1, 4-year-old mature live fly maggots bred by bran and distiller' S grains are screened to remove impurities.
Further, the intestine clearing of S2 is carried out at 15-20 deg.C, stopping feeding, temporarily culturing for 12 hr, removing in vivo waste and reducing heavy metal content.
Further, the volume ratio of the silver ion hydrogen peroxide disinfectant to the sodium hypochlorite disinfectant in the S3 is 1: 1, mixing and sterilizing simultaneously, wherein the concentration of hydrogen peroxide in the silver ion hydrogen peroxide disinfectant is 4.0-6.5%, the concentration of silver ions is less than or equal to 0.01%, and the concentration of sodium hypochlorite in the sodium hypochlorite disinfectant is 4.0-4.9%.
Further, in S3, pure water is adopted for rinsing and detoxifying for 3 times, 5 minutes each time, and the dead maggots and the inferior maggots which float in the bubbles are removed.
Further, in S5, microwave sterilization is used.
Has the advantages that: compared with the prior art, the invention has the advantages that: fresh and alive fly maggots are made into powder through a unique sterilization preparation process, and the contents of heavy metal and pathogenic bacteria of the fly maggots are strictly controlled at an edible level while the nutritional value of the fly maggots is kept; the heavy metal content of the fly maggot freeze-dried powder can be controlled: lead is less than 0.6mg/kg, total arsenic is less than 0.1mg/kg, total mercury
