Extraction method of MD (musca domestica) insect active protein intermediate

Abstract

The invention discloses an extraction method of an MD (musca domestica) insect active protein intermediate, comprising the following steps: cleaning and drying MD larva; after drying the MD larva by blowing at 40 DEG C, smashing the dried product; fully degreasing; adding 1-1.5% of alkali, and adding water for hydrolysis at constant temperature; secondarily desalting; and freezing and drying leached and desalted precipitate. Because the above technical scheme is adopted, technological operation difficulty is greatly lowered and production cost is greatly lowered by changing complex dialysis desalting with high cost into the secondary desalting; in the process of secondary desalting, hydrolyzate is required to be precipitated and AgNO3 is not needed to be used for detection, which protects the health of workers; and in the working procedure of drying the original substance by blowing at 40 DEG C after cleaning and drying, considerable energy can be saved, equipment investment and manual work are reduced if compared with the alkali dilution method of the Institute of Zoology of Chinese Academy of Sciences that the original substance is boiled for 15 minutes and is frozen and dried, and thus production cost is greatly lowered.

Description

technical field [0001] The invention relates to a method for extracting an MD insect active protein intermediate. Background technique [0002] Insect active protein is the third generation protein after plant protein and animal protein. It not only has the functions of plant protein and animal protein to increase the nitrogen source of the human body and supplement nutrition, but also has the magical substances and various activities that plant protein and animal protein lack, and has a strong special effect on the cells, organs and tissues of the human body. It has special functions and functions of absorption, utilization and transformation, as well as the functions of repairing human cells, inhibiting and killing human viruses and pathogenic bacteria. [0003] It is unanimously recognized by the world's biological and nutritional circles that MD insect active protein has the advantages of functions and effects in all aspects, ranking first among all insect active protei...

AI Technical Summary

Problems solved by technology

[0006] However, this method does not allow the existence of precipitates in the extract, that is, the leached protein is completely dissolved in the extract, and the process greatly increases the workload of freeze-drying, greatly increases equipment investment and production costs such as labor and power consumption. Impossible for mass production

The method uses AgNO 3 , has a great impact on the health of workers and the environment, and the process operation is difficult and the production cost is high

And all do not relate to the waste water treatment step in the technology in the prior art
