A continuous production method of high-activity fly maggot protein powder

Abstract

The invention relates to a continuous production method of high-activity fly maggot protein powder and belongs to the technical field of processing of edible protein. According to the processes, the high-activity fly maggot protein powder is prepared by adopting fresh fly maggots as a raw material and by steps of cleaning, colloid milling and smashing, superfine grinding, degreasing, removing dregs, performing vacuum low-temperature continuous drying, smashing, and sterilizing with rays. By adoption of the vacuum low-temperature continuous drying process, the activity of the fly maggot protein can be maintained furthest, the process time is shortened and the production cost is reduced. By adoption of the superfine grinding process, the fly maggot skin can be grinded into particles having a size of 2-10 [mu], and the most of the particles can be maintained in the fly maggot protein powder, thus preventing loss of the active component chitin in the fly maggot skin and facilitating absorption of the chitin in the fly maggot skin by the human body. By adoption of the processes of degreasing and removing the dregs, the most of fishy smell and peculiar smell can be removed, and the durability time can be prolonged.

Description

technical field [0001] The invention relates to a continuous production method of highly active fly maggot protein powder, which belongs to the technical field of edible protein processing. Background technique [0002] Fly maggot protein contains chitin, antimicrobial peptide protein, defensin, interferon, exogenous lectin and amino acids and other extraordinary active substances, making it a popular choice for human beings in immune regulation, detoxification, anti-bacterial virus and anti-tumor. Precious biomedical resources. [0003] my country has long had the technology of feeding and breeding fly maggots, but it is mainly used as animal feed. In recent years, with the improvement of people's awareness of fly maggot protein, the development and utilization of fly maggot protein has turned to health food. [0004] At present, fly maggot protein powder as a health food has appeared on the market, but there are generally problems such as few active ingredients, heavy fi...

AI Technical Summary

Problems solved by technology

[0004] At present, fly maggot protein powder as a health food has appeared on the market, but there are generally problems such as few active ingredients, heavy fishy and peculiar smell, and bad taste. The reasons are:

[0005] (1) The spray drying process is generally used, and the production temperature needs to be above 100 degrees, which destroys the activity of the fly maggot protein

[0006] (2) the single-stage rubber mill that generally adopts is difficult to pulverize the fly maggot skin to a small enough particle size, and most of the fly maggot skin is filtered out to become residue, because more than 90% of the fly maggot skin is chitin, and the chitin is again It is the main source of fly maggot protein activity, so it loses many activities of fly maggot protein

[0007] (3) Effective deodorization and deodorization processes are generally not adopted

[0009] (1) fly maggot skin is sloughed off after protein and is filtered out, because the main component of fly maggot skin is chitin, so the fly maggot protein powder of making can lose many chitin activities;

[0010] (2) Maillard reaction requires a high temperature of 100-125°C for deodorization and aroma enhancement, and the reaction time is long, which destroys the activity of fly maggot protein, and, according to the patented product that has been put on the market, it still has a relatively heavy fishy smell and peculiar smell The actual effect shows that the effect of this process to remove fishy smell is not obvious;

[0011] (3) Spray-drying process destroys fly maggot protein activity
