Problems solved by technology

[0003] Because ginseng needs to prevent pests during planting, pesticides will be sprayed, causing soil damage. During the growth process, ginseng absorbs nutrients in the soil and also absorbs some pesticide residues, resulting in excessive pesticide residues in ginseng extracts. Phenol is a pesticide residue that widely exists in ginseng extracts. The current general method for removing pesticide residues is solvent extraction. Due to polarity problems, the extraction efficiency is low, especially at the ppb level. Emulsification will cause loss of saponin and increase the difficulty of operation

Abstract

The invention discloses a device for removing residual dimethomorph residues in ginsenoside extracts. Dimethomorph is a pesticide residue widely present in ginseng extracts. The current general method for removing pesticide residues is solvent extraction. Sexuality leads to low extraction efficiency, especially at the ppb level, which is difficult to remove. In addition, the emulsification that occurs during the extraction process will cause loss of saponins and increase the difficulty of operation. In the present invention, the ginsenoside solution is treated with a ceramic membrane, and then the first electric door is opened to collect the permeated liquid of the ceramic membrane, and ethyl acetate and After the n-hexane mixture is clarified through the ceramic membrane, the suspended solids in the liquid are retained, and the clarity of the feed liquid is high; the temperature rise can effectively reduce the occurrence of emulsification; the recovery rate of the product saponin can reach more than 95%, and this mixed solvent It has the highest solubility for dimethomorph, and can remove dimethomorph residues in ginsenoside extracts to below 10ppb.

Description

technical field [0001] The invention relates to the technical field of pesticide removal, in particular to a device and method for removing residual dimorpholine residues in ginsenoside extracts. Background technique [0002] Dimethomorph is a specific agent for the control of oomycete fungal diseases. It is mainly used for downy mildew and late blight of plants. It belongs to fat-soluble pesticide residues. It has strong stability in solution and is not easy to degrade. Organic solvent extraction method It belongs to the most common and simple purification and impurity removal method, which is to use the difference in solubility of solutes in immiscible solvents to extract solutes from a solution composed of another solvent with one solvent. [0003] Because ginseng needs to prevent insect pests during the planting process, it will spray pesticides, causing soil damage. During the growth process, ginseng absorbs nutrients in the soil and also absorbs some pesticide residues...
