Problems solved by technology

Under the circumstances that the current market management is not perfect and there is a lack of simple and practical rapid detection methods for pesticide residues, safe removal of pesticide residues in vegetables and fruits is one of the effective measures to reduce the impact of pesticide residues on health
Simple washing with water in daily life often cannot effectively remove pesticide residues in vegetables and fruits; washing with ordinary detergent can wash away some residual pesticides, but the residue of detergent itself will also have adverse effects on human health
Because the cleaning agents currently on the market mainly use sodium dodecylsulfonate as the main raw material, which has poor solubility to residual pesticides and is easy to keratinize human skin, and its residues also have a certain impact on human health. However, there are few reports on the scavenger specially used for removing residual pesticides in vegetables and fruits.

Embodiment Construction

[0012] The following examples illustrate the invention in detail. In these examples, all percentages are percentages by weight unless otherwise specified.

[0013] According to this technical scheme, the product produced according to the foregoing process is referred to as "Xiaocanling", and its component ratio: tea saponin 12%, sodium carbonate 5%, and sodium bicarbonate 4%. The removal effect test and toxicity test are as follows:

[0014] Separately spray 1000 times solution of Saidan and 1000 times solution of chlorpyrifos evenly on the "Shanghai Green" vegetables, and pick the leaves for the experiment after 3 days. Take 500 grams of the above vegetable leaves respectively, soak them in 1000 times liquid of "Xiaocanling", 2000 times liquid of "Xiaocanling", 2000 times liquid of a control common detergent, and 2 kilograms of clean water for 10 minutes. Take out and rinse with clean water Clean, dry, and measure pesticide residues. Test three times.

[0015] The above-mentioned...

Abstract

A natural scavenger for removing persistent pesticide on vegetable and fruit is prepared from teasaponin, sodium carbonate and sodium bicarbonate. The prepared scavenger uses extracts from natural plants as raw materials so it does not have toxicity to human being and animal.

Description

Technical field [0001] The invention belongs to the technical field of detergents, and specifically relates to a natural scavenger for pesticide residues in vegetables and fruits. Background technique [0002] The impact of pesticide residues in vegetables and fruits on human health has been widely concerned, and food poisoning incidents caused by the consumption of vegetables and fruits containing pesticide residues have also occurred from time to time. In the current market management is not perfect, and there is no simple and practical method for rapid detection of residual pesticides, the safe removal of residual pesticides in vegetables and fruits is one of the effective measures to reduce the impact of residual pesticides on health. Simple water washing in daily life is often not effective in removing pesticide residues in vegetables and fruits; although washing with ordinary detergents can wash away some of the residual pesticides, the detergent residues themselves will al...
