Embodiment 1

[0024] Carry out the extraction of cockroach extract and its medicinal and edible substances according to the following steps:

[0025] A. Alcohol extraction:

[0026] 1) Inactivate the raw material cockroaches with 65-75°C hot water;

[0027] 2) After drying at 65-75°C, coarsely pulverize and sieve;

[0028] 3) Put it in a container, soak the surface of the raw material in 80-degree alcohol for 48 hours;

[0029] 4) Put the above-mentioned treated matter into a multi-functional extractor, add 3 times of 80% alcohol, heat reflux extraction for 7 hours, start to recover alcohol, and the temperature of the whole process of alcohol extraction is 75°C;

[0030] 5) Recover the medicinal liquid and put it in the separator for oil-water separation;

[0031] 6) The separated medicinal liquid is filtered through a microporous filter;

[0032] 7) Put the filtrate in a vacuum concentrator to concentrate to a concentration of 1:1.3, release and cool the extract, and the temperature of...

Abstract

The invention discloses a method for extracting medicinal and edible substance from dictyoptera which comprises, killing raw material cockroach with hot-water, drying by high temperature, coarse disintegrating, sieving, steeping with alcohol, extracting by alcohol hot reflux, obtaining extract from the residual through water extraction, extracting amino acid, polypeptides, protein, chitosan, chitosan from the residues.

Description

technical field [0001] The invention relates to a method for extracting medicinal and edible substances from cockroaches. Background technique [0002] Cockroach (Periplaneta) is a type of insect (cockroach). The products extracted from cockroaches can be used in skin care products, medicines, health care products, etc. It has the effect of promoting tissue growth and healing and anti-oxidation. It can sober up and protect the liver, nourish the stomach, promote the healing of gastric ulcer and duodenal ulcer, and promote inflammation and ulcers. Healing, and has auxiliary therapeutic effect on tumors, deficiency syndromes, and tuberculosis. The existing cockroach (also called Periplaneta americana) extraction process adopts the traditional alcohol extraction method, most of the water-soluble amino acids have not been proposed, the extraction rate is only 8.7-10.3%, and the total amino acid content of the product is only 29.8%. %. [0003] The inventor's previous patent a...
