Cleaning solution for removing pesticide residues and heavy metal pollution of fruits and vegetables

Abstract

The invention discloses a cleaning solution for removing pesticide residues and heavy metal pollution of fruits and vegetables. The cleaning solution is characterized by comprising an active componentA and an active component B. The active component A refers to rhamnolipid, and the active component B refers to one or two of sodium glucoheptonate or sodium N-dodecanoyl ethylenediamine triacetate.The weight ratio of the active component A to the active component B is (50:1)-(1:50), preferably (10:1)-(1:10), and the total weight percentage of the two active components in the cleaning solution is 0.1%-70%. The cleaning solution can be used for removing pesticide residues and heavy metal pollution on the surfaces of fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of removing pesticide residues, in particular to a cleaning solution for removing pesticide residues and heavy metal pollution in fruits and vegetables. Background technique [0002] Rhamnolipids are biosurfactants of biometabolic properties produced by Pseudomonas or Burkholderia species. It is also a biosurfactant with the longest research time and the most mature application technology. It occurs naturally in soil, water bodies and plants. It belongs to a glycolipid anionic surfactant with good chemical and biological properties. It has oil and water amphiphilicity and can reduce the surface tension of water. It can be used as a wetting agent, emulsifier and foaming agent. The biosurfactant can be used under extreme conditions of temperature, pH value and salinity, and is non-toxic and biodegradable. [0003] Sodium Glucoheptonate is a biodegradable high-efficiency surfactant and metal ion chelating ag...

Problems solved by technology

[0006] There are few products 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 secondary pollution problems 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 shedding and degrading pesticide factors. It 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 relatively high; CN 102690738A discloses a pesticide residue antidote specially used in fruits and vegetables. The antidote has the problems of incomplete degradation of residual pesticides, peculiar smell or secondary pollution of phytochemical components in the antidote
