A method for preparing silkworm powder

Abstract

The present invention relates to a kind of novel full silkworm powder with a plurality of healthcare functions and its preparation comprising: collecting silkworm larvae at the third day in five-instar, killing it immediately, keeping it at low temperature (below minus 20 degree), followed by the biological conversion processes of sanitizing, degreasing and protein and other macromolecular substances decomposing, dehydrating and drying, freeze drying at ultra-low temperature (minus 60 degree) and finally crushing into superfine powder below 180 mesh. The product maintains the original active substances in the silkworm body, has no side effect and is characterized in multiple healthcare functions such as reducing blood sugar, blood fat and improving immunity function.

Description

technical field

[0001] The invention relates to a method for preparing whole silkworm powder with multiple health-care functions. Background technique

[0002] Bombyx mori has hypoglycemic effect has been confirmed by more and more researches. For example, silkworm powder (CN95115559.8) is prepared by anti-oxidizing and freeze-drying the 4th to 5th instar silkworms with nitrogen gas; the fresh and healthy silkworms in the early fifth instars are cleaned to remove impurities and sterilized. and the whole silkworm powder (CN03116235.5) obtained by vacuum freeze-drying; quick-freezing or directly placing live silkworms in freeze-vacuum drying to make a compound preparation (CN200410017227.3) of the prepared silkworm powder and other traditional Chinese medicine extracts. Some have a single health-care effect, and some have a compound effect of silkworm powder and other Chinese herbal medicines. Some preparation methods are relatively complicated or have high requirements for e...

Embodiment Construction

[0013] The preparation steps of the present invention are as follows:

[0014] 1. Breeding and preparation of silkworms. According to conventional feeding methods, collect and clean up the silkworm larvae on the 3rd day of the 5th instar, kill them immediately, and quickly store them at low temperature (below -20°C);

[0015] 2. Biotransformation. Put the low-temperature-treated silkworm in an alcohol solution to sterilize, degrease, decompose protein and other macromolecular substances, and then dehydrate and dry;

[0016] 3. Ultra-low temperature freeze-drying. The dehydrated and dried silkworm enters an ultra-low temperature (below -60° C.) freeze dryer for ultra-low temperature freeze-drying until completely dry.

[0017] 4. Superfine crushing. The dried silkworm is ultrafinely pulverized to below 180 mesh.

[0018] The output of the present invention is that each box of silkworm eggs (about 25,000 silkworms) can produce 6 kg of silkworm powder, and the original activ...
