Process for extracting bread worm protein

Abstract

The present invention is the bread worm protein extracting process with less nutritious matter loss. The technological scheme includes: stoving bread worm, stirring to form slurry, degreasing and filtering, adding salt or alkali to dissolving the coarse protein in the lower layer, isoelectric point salting-out or dialysis to coagulate and precipitate protein, stoving the precipitate to obtain bread worm protein. The present invention can extract bread worm protein accounting for 35.3-71.4 wt% of bread worm body and maintain the nutritious components effectively. The extracting process has harmless solvent oil used as the organic solvent, and may be applied in industrial production.

Description

1. Technical field: [0001] The invention relates to an insect protein extraction technology, in particular to an extraction process of Tenebrio molitor protein which reduces the loss of nutrients in Tenebrio molitor during the dehydration process. 2. Background technology: [0002] Protein is the basic substance of life. Under the trend of rapid population growth in the world, the demand for protein will increase, and conventional protein foods such as milk, eggs, fish, and meat will be far from meeting people's needs for protein. Therefore, developing new types of food and seeking new sources of protein have become an urgent task before human beings. Because insects have the characteristics of high protein content, less protein fiber, easy absorption of nutrients by the human body, short reproductive generations, high reproductive index, suitable for factory production, and rich resources, they have become the most promising protein food resources and are widely accepted. ...

AI Technical Summary

Problems solved by technology

[0004] At present, the problems existing in the application of Tenebrio molitor resources in my country, Europe, Japan, South Korea and other countries are: it is still in the stage of breeding as live feed, and the processing of Tenebrio molitor is only to dry the insect body and make the pupae into dishes , and the nutrients of Tenebrio molitor cannot be fully utilized, and the existing drying methods cause a large amount of denaturation of protein in Tenebrio molitor, let alone use it as human food or food additives
