[0007] (2) Ganoderma cultivation method: During the cultivation process of Ganoderma lucidum, such as the sterilization of bacteria and basswood, it needs to be wrapped in PE plastic bags and sterilized at high temperature for a long time. During this process, plasticizer components will leak out , and will be absorbed by the culture medium or basswood. During the cultivation and development of Ganoderma lucidum, it will be absorbed and accumulated in the spore powder of Ganoderma lucidum, causing plasticizer pollution
[0008] (3) Collection method of Ganoderma lucidum spore powder: For example, the collection of Ganoderma lucidum spore powder in the place of origin is directly sprayed on the PE plastic film, which is also very easy to cause pollution
[0010] Plasticizer components are more harmful to the body, and there is a risk of plasticizer pollution in Ganoderma lucidum spore powder. Therefore, it is necessary to invent a method to remove the plasticizer in Ganoderma lucidum spore powder, but there is no effective method at this stage.

Abstract

The invention discloses a method for removing plasticizer residual and contaminant from ganoderma lucidum spores powder raw materials. The method comprises the following steps: breaking walls of ganoderma lucidum spore powder, adding the ganoderma lucidum spore powder to an extraction kettle of a supercritical CO2 extraction device, wherein the extraction pressure is 8-12MPa, the extraction temperature is 20-40 DEG C, the separation pressure of a separation kettle I is 4-6MPa, the separation temperature of the separation kettle I is 20-40 DEG C, the separation pressure of a separation kettle II is 4-6MPa, the separation temperature of the separation kettle II is 20-40 DEG C, the CO2 flow is 100-200L / h, and the extraction time is 2-6h; and after the extraction is completed, opening the extraction kettle and taking out the product. The method has the advantages that the method is simple in operation, active ingredients of the ganoderma lucidum spore powder can be preserved to the maximum, plasticizer can be effectively removed, and the safety of the product is ensured. The solvent carbon dioxide used in the method is an inert gas, is safe and non-toxic, can completely volatilize, and does not generate physical or chemical reaction with the product or generate contamination. By adopting the method, the plasticizer can be completely removed from the ganoderma lucidum spores powder.

Description

technical field [0001] The invention relates to a method for removing plasticizer residue and pollution in raw materials of ganoderma lucidum spore powder. Background technique [0002] Plasticizers, also known as plasticizers, are polymer additives widely used in industry, but illegal traders add them to food additives, causing food safety incidents that shocked the world. Plasticizers are classified as suspected environmental hormones, and their biological toxicity is mainly estrogenic and anti-androgenic, which can cause endocrine disorders, hinder the reproductive function of organisms, cause malignant tumors, and cause deformed children. The potential harm to young children will be greater, and may cause gender confusion in children, including shortened genitals, indistinct sexual characteristics, or precocious puberty in children. [0003] Since May 2011, six phthalate plasticizers including DEHP, DINP, DNOP, DBP, DMP, and DEP have been detected in food in Taiwan, and...
