AI Technical Summary

Problems solved by technology

However, the main defects in the method of directly preparing dry powder from housefly larvae in the prior art are: the problems of protein browning and removal of worm body intestinal dirt are not solved, spray drying destroys material components that are not resistant to high temperatures, microwave sterilization The active material is destroyed, and the process is complicated and the cost is high
Especially in the preparation process of the existing housefly larva nutrition powder, no induction and stimulation process is used, so there is no physiologically active substance in the nutrition powder, which greatly reduces its curative effect and nutritional value

Embodiment 1

[0009] a. Biological induction: when the larvae are 4 days old, feed 1850 grams of larvae with 50 ml of inactivated Escherichia coli liquid, and then feed them with Gram-negative bacteria liquid after 4-8 hours 50ml, after 4-8 hours, feed it with 50ml of Gram-positive bacteria liquid for biological induction;

[0010] b. Intestinal cleansing: sort the larvae that have reached the age of 5 days after induction and the feed, and let them stand at 18°C ​​for 6 hours until there is no black residue in the worms, and then clean the intestines;

[0011] c. Inhibit the activity of pro-polyphenol oxidase: place the larvae after bowel cleansing in a 60khz 70w ultrasonic cleaner for 12 minutes to suppress the activity of pro-polyphenol oxidase and prevent the formation of quinones;

[0012] d. Disinfection: Place the larvae after bowel cleansing in purified water at 55°C, pass through ozone 0.2mg / L, carry out disinfection and kill the larvae, and drain the water after 8 minutes;

[001...

Embodiment 2

[0016] a, biological induction: when the larvae reach the age of 4 days, 2100 grams of larvae are continuously fed with inactivated Escherichia coli bacterial liquid, Gram-negative bacterial liquid and Gram-positive bacterial liquid each once, Feed 50ml each time;

[0017] b. Intestinal cleansing: sort the larvae that have reached the age of 5 days after induction and the feed, and let them stand at 20°C for 10 hours until there is no black residue in the worms, and then clean the intestines;

[0018] c. Inhibit the activity of propolyphenol oxidase: place the larvae after bowel cleansing in a 60khz 70w ultrasonic cleaner for 10 minutes to suppress the activity of propolyphenol oxidase and prevent the formation of quinones;

[0019] d. Disinfection: place the larvae treated in c in purified water at 65°C, and then inject 0.4 mg / L of ozone to disinfect and kill the larvae. After 10 minutes, drain the water;

[0020] e. Drying: freeze-dry the sterilized larvae at -45°C for 20 h...

Embodiment 3

[0023] a, biological induction: when the larvae are 4 days old, feed 2350 grams of larvae with 50 ml of Escherichia coli bacterium liquid through inactivation treatment, after 8 hours, feed 50 ml of Gram-negative bacteria bacterium liquid to it, 8 hours After one hour, feed it with 50ml of Gram-positive bacteria liquid to carry out biological induction;

[0024] b. Intestinal cleansing: sort the larvae that have reached the age of 5 days after induction and the feed, and let them stand at 23°C for 11 hours until there is no black residue in the worms, and then clean the intestines;

[0025] c. Inhibit the activity of propolyphenol oxidase: place the larvae after bowel cleansing in a 60khz 70w ultrasonic cleaner for 13 minutes; inhibit the activity of propolyphenol oxidase and prevent the formation of quinones;

[0026] d. Disinfection: place the larvae treated in c in purified water at 80°C, and then inject 0.6 mg / L of ozone to disinfect and kill the larvae. After 15 minutes, ...

Abstract

The invention relates to a preparing method of nutrition powder of freeze-drying house fly grub, belonging to the preparation of health products. Imago is cultivated to lay eggs incubated to grubs which would be feed eschenrichia coli solution, gram-negative bacteria solution, and gram-positive bacteria solution each 50 ml when they are 4 days old; five days old grubs induced are selected to be laid for 5-11 hours in 15-25 Deg. C; the grubs are processed in ultrasonic cleaner of 60 kHz and 70 w for 8-15 minutes; the grubs are disinfected and killed in purified water of 50-80 Deg. C added ozone (0.2-0.6 mg / L) and remove the water of grubs in 8-15 minutes; freeze-drying the grubs for 14-22 hours in -35 to -50 Deg. C; disintegrating the grubs to 300 deals powder in -10 to 10 Deg. C which is the nutrition powder of freeze-drying house fly grub. Said inventive nutrition powder iwithout browning and peculiar smell is full in nutrition function and easy at process.

Description

technical field [0001] The invention belongs to the preparation of health products, in particular to a preparation method of housefly larvae freeze-dried nutrition powder. Background technique [0002] In recent years, the analysis of the components of housefly larvae at home and abroad has found that housefly larvae are a kind of insect resource with great nutritional and health effects. As the preparation of its nutritional powder, existing reports, such as: "Food Industry Science and Technology" in 1998 Phase 2, Patent Application Publication CN95117851, "Resource Development and Market" Volume 15 Phase 1 in 1999, "Journal of Changsha Electric Power Institute (Natural Science Edition) Volume 14 Phase 1" in 1998, "Food Industry" in 2002 Science and Technology, Volume 23, Issue 12. However, the main defects in the method of directly preparing dry powder from housefly larvae in the prior art are: the problems of protein browning and removal of worm body intestinal dirt are ...
