Problems solved by technology

However, due to the living environment and habits of termites, their own heavy metal content is very high. The content of lead and manganese in termite extracts is several times or dozens of times higher than that required by health care product standards, which directly affects the development and utilization of termites.

Embodiment 1

[0020] A method for removing heavy metals in termite extracts by combined use of chelating resins, the specific steps are:

[0021] (1) Preparation of termite extract

[0022] After the termites are washed and dried, dry termite products are obtained, which are weighed and crushed through a 60-mesh sieve for later use.

[0023] Put the crushed termite powder into the extraction tank, add 8 times the quality of purified water, then add 2% termite powder mass lipase, and 4% termite powder mass protease, and enzymolyze it at a temperature of 40 degrees 6 hours,

[0024] The enzymolysis solution is released from the extraction tank, filtered through 80 mesh, and then filtered by a centrifuge, and the filtrate is collected as termite extract, which is ready for use;

[0025] (2) Selection and treatment of chelating resin

[0026] The method of using two resins in combination, A: macroporous styrene-divinylbenzene chelating resin, B: macroporous acrylic copolymer (with carboxylic...

Abstract

The invention discloses a combined chelating resin method for removal of heavy metals in a termite extract. The termite is extracted into a termite extract by a compound enzyme, and the termite extract has heavy metals removed by the chelating resin. The method removes the metal ions, does not influence the other contents of the effective component in the extraction liquid. The content of lead and manganese in the termite extract powder is decreased by more than 97%, so that the termite extract powder can be used as a raw material for health food, and is in line with the standard of health food. The method of the invention is simple, and significant in effect, does not affect the effective composition of product or cause secondary pollution, and is a good method applicable to scale production.

Description

technical field [0001] The invention relates to a method for removing heavy metals in termite extracts, in particular to a method for removing heavy metals in termite extracts in combination with chelating resins. Background technique [0002] Termites (mainly referring to the yellow-winged termites, black-winged termites, house termites) have certain medicinal value and health care function. In recent years, many health care products have been researched and developed with termites, which have the functions of anti-fatigue and reducing chemical liver damage in the human body. However, due to the living environment and habits of termites, their own heavy metal content is very high. The content of lead and manganese in termite extracts is several times or dozens of times higher than that required by health care product standards, which directly affects the development and utilization of termites. Contents of the invention [0003] The object of this invention is to provide...
