Fruit and vegetable washing salt for strongly removing pesticide residues based on dual mechanisms of adsorption and removal functions

Abstract

The invention discloses fruit and vegetable washing salt for strongly removing pesticide residues based on dual mechanisms of adsorption and removal functions. The fruit and vegetable washing salt is formed by combining one or more of the following raw materials: sodium chloride, a natural adsorption material, a biomass surfactant and a decontamination assistant. For avoiding potential safety hazards of food in real life, people often use a neutralization reaction to remove acidic pesticide residues on the surfaces of fruits and vegetables, while pesticide is acidic or alkaline, and the pesticide residues cannot be completely removed by means of the neutralization reaction only. According to the fruit and vegetable washing salt disclosed by the invention, the pesticide residues on the surfaces of the fruits and the vegetables are adsorbed by using the natural adsorption material; besides, pesticide is eluted by means of a demulsification effect of the salt; dual mechanisms of adsorption and removal are combined to strongly remove the pesticide residues; and moreover, the damage to nutritional value and mouth feel of the fruits and the vegetables is avoided. The raw materials adopted by the fruit and vegetable washing salt disclosed by the invention have the characteristics of nature, no toxicity or harm, no chemical components such as essence, no pollution to water quality, wide sources, safety, effectiveness and no side effects; and a preparation process is simple and feasible and the popularization value is relatively high.

Description

technical field [0001] The invention belongs to the field of salt, in particular to the field of washing salt, in particular to a fruit and vegetable washing salt that can effectively remove pesticide residues based on a dual mechanism of absorption and desorption functions. Background technique [0002] With the improvement of living standards of contemporary people, people pay more and more attention to nutrition and health, and fruits and vegetables are more and more popular. With the expansion of the fruit and vegetable market, a large number of pesticides are used to treat fruits and vegetables in the production and circulation of fruits and vegetables. Pesticide residues have become a major health hazard. If you eat fruits and vegetables with pesticides for a long time, the harmful substances in the pesticides will be continuously introduced into the human body, and in severe cases, they will be enriched in the human body, which will continue to endanger human health ...

AI Technical Summary

Problems solved by technology

However, simply using the demulsification effect of salt to perform a simple "detachment" cannot completely remove the pesticide residues on the surface of fruits and vegetables, because the removed pesticides and agglomerated surfactants are likely to re-adhere to the fruits and vegetables during the washing process surface
