Problems solved by technology

[0005] There are few products used for cleaning and detoxifying fruit and vegetable pesticide residues in the domestic market, among which liquid fruit and vegetable cleaning agents are mainly chemically synthesized surfactants, which have the problem of secondary pollution of surfactant residues; biological cleaning solutions (degradative enzymes) on the market ), using protease to destroy and decompose the structure of residual pesticides to achieve the purpose of pesticide factor shedding and degradation, which is only effective for specific types of pesticides, and its economic cost is high and it is not easy to promote
Commercially available solid powder fruit and vegetable cleaning agents are mainly composed of calcined shell powder and edible alkali, which decompose acidic residual pesticides through physical adsorption or weak alkalinity, which has the problem of single action principle, and the removal or decomposition of alkaline pesticide residues is not thorough enough
CN 101438774A discloses a detoxification and cleaning agent for pesticide residues in fruits and vegetables. The detoxification and cleaning agent is prepared by mixing emulsifier, fruit acid, citric acid, biological enzyme, stabilizer, defoamer, thickener, essence and distilled water in proportion. The composition is complex The cost is high; CN 102690738A discloses a pesticide residue antidote specially used in fruits and vegetables, which has the problems of incomplete degradation of residual pesticides and secondary pollution of phytochemical components in the antidote

Embodiment 1

[0010] Embodiment 1: powder preparation

[0011] The composition for removing pesticide residues in fruits and vegetables is a powder.

[0012] The parts by weight of each component are as follows:

[0013]

[0014] The specific production steps of the powder are as follows: firstly add the carrier calcium carbonate and calcium hydroxide into the stirring tank for stirring, then add the active components A and B in turn, then stir and mix evenly at high speed, and then pulverize and mix with a low-temperature airflow fine pulverizer to produce Composition powder of the present invention.

Embodiment 2

[0015] Embodiment 2: preparation of granules

[0016] The composition for removing pesticide residues in fruits and vegetables is a granule.

[0017] The parts by weight of each component are as follows:

[0018]

[0019] The specific production steps are first fully stirring the active components calcium oligosaccharide and titanium citrate in the stirring tank, then spraying the sodium carboxymethyl cellulose solution through the fluidized bed granulation equipment at the same time, and continuously granulating and drying on the vibrating screen. Dry and sieve to obtain the composition granules of the present invention.

Embodiment 3

[0020] Embodiment 3: effervescent tablet preparation

[0021] The composition for removing pesticide residues in fruits and vegetables is an effervescent tablet.

[0022] The mass parts of each component are as follows:

[0023]

[0024] Separate granulation method is adopted, the solvent of binder is dissolved in non-aqueous solvent, active component is granulated with sodium bicarbonate and citric acid respectively in anhydrous condition or dry environment to prepare alkaline granules and acidic granules for later use, and then After sieving, select 40-70 mesh granules, mix the two kinds of granules with starch, press into tablets, reshape and seal the package to obtain the effervescent tablet of the composition of the present invention.

Abstract

The invention discloses a composition for removing pesticide residues on fruits and vegetables. The composition is characterized by comprising an active component A and an active component B, whereinthe active component A is chitosan oligosaccharide calcium, the active component B is titanium citrate, a weight ratio of the active component A to the active component B is 60: 1 to 1: 60, preferably8: 1 to 1: 8, and the total weight percentage of the two active components in the composition is 0.01%-80%. The dosage form of the composition is one selected from the group consisting of powder, granules and effervescent tablets. The composition disclosed by the invention can be used for removing various pesticide residues on fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of removing pesticide residues, in particular to a composition for removing pesticide residues in fruits and vegetables. Background technique [0002] Chitosan oligosaccharide calcium is a chitosan oligosaccharide calcium complex synthesized by reacting chitosan oligosaccharide with saturated calcium chloride solution. The -NH2 and -OH on the chitosan oligosaccharide molecule have a good chelating ability for calcium ions. Chitosan oligosaccharide calcium can promote the breaking of the phosphate bond of organophosphorus pesticides, reduce the toxicity of organophosphorus pesticides, and thus achieve the effect of hydrolyzing organophosphorus pesticides. [0003] Titanium citrate is a kind of photoactive substance, which has good photocatalytic performance under visible light, sunlight or eye light, has good antibacterial and decomposing harmful substances, and can effectively decompose and remove residues o...
