Abstract
The invention discloses a method for removing residual pesticide in plant extract. The method comprises the following steps: dissolving plant extract powder in purified water; adsorbing through ion exchange resin; collecting effluent; adding adsorbent to the effluent; ensuring that the ratio of the milliliter value of the effluent to the gram value of the adsorbent is 1000:1-5; raising temperature to between 40 and 80 DEG C; stirring for 1 to 3 hours; filtering the obtained product; concentrating filtrate and spray-drying the obtained product to form fine powder. The method has the advantages of capability of reducing the amount of residual pesticide in plant extract, guaranteeing the health of citizens and reaching international standards, simple operation, low cost and easiness for industrialization.
Description
Technical field
The present invention works out a kind of method of removing remains of pesticide, particularly relates to the method for removing remains of pesticide in the plant extracts.
Background technology
Residues of pesticides are that agricultural chemicals uses and is not decomposed in the back period and residues in the general name of trace pesticide substance, toxic metabolite, degradation product and impurity in organism, cutting, soil, water body, the atmosphere.The World Health Organization and FAO (Food and Agriculture Organization of the United Nation) (WHO/FAO) are defined as Pesticide Residue, according to good agricultural production (GAP) standard, directly or indirectly use agricultural chemicals after, the Cmax of the pesticide residue that in food and feed, forms.At first according to the toxicity assessment of agricultural chemicals and residue thereof, GAP and safe and reasonable according to country's promulgation are used the agricultural chemicals standard, the control needs that adapt to national various disease and pests, under tight technical supervision, under the prerequisite of effectively prevention and elimination of disease and pests, in a series of residual datas of obtaining, get representational high value.Its direct effect is a persticide residue in the restriction agricultural product, ensures that the citizen is healthy.In today of world's trade integration, the agricultural chemicals MRL also becomes important techniques barrier between each trading country.Countries in the world, particularly developed country are paid much attention to the residues of pesticides problem, and residues of pesticides in the various agricultural byproducts have all been stipulated more and more stricter limit standard.Many countries are technology barriers with the Pesticide Residue, the import of restriction agricultural byproducts, protection agricultural production.Now, because these technology barriers of residues of pesticides, the outlet of Chinese Plants extract is faced with formidable challenges.
Summary of the invention
Purpose of the present invention solves these technology barriers of residues of pesticides in the plant extracts, works out a kind of method of removing remains of pesticide in the plant extracts, causes that Pesticide Residue meets international standards in the plant extracts.
Technical scheme of the present invention is summarized as follows:
A kind of method of removing remains of pesticide in the plant extracts, its feature comprise the steps: that (1) is that 1: 10～50 ratio is dissolved in plant extracts powder art in the purified water in mass ratio, through ion exchange resin absorption, collect and flow out liquid; (2) add adsorbent in described outflow liquid, it is 1000: 1～5 that the milliliter number of described outflow liquid is counted ratio with the gram of adsorbent, is warming up to 40 ℃-80 ℃, stirs 1-3 hour, filters, and filtered fluid concentrates, and is spray dried to fine powder.
Described ion exchange resin is 001 * 7 type cationic ion-exchange resin or D001 type cationic ion-exchange resin.
Described adsorbent is active carbon or aluminium oxide.
Advantage of the present invention is:
Method of the present invention can make the plant extracts persticide residue descend, and ensures that the citizen is healthy, meets international standards, and method of the present invention is simple to operate, and cost is low, is easy to industrialization.
