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 examples described below illustrate the invention in detail. In these examples, all percentages are by weight unless otherwise indicated.

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

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

[0015] The above test data and analysis conclusions are as follows:

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, in particular 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 incidents of food poisoning caused by eating vegetables and fruits containing pesticide residues also occur from time to time. 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 residual pesticides in vegetables and fruits; washing with ordinary detergent can wash away some residual pesticides, but the residual detergent ...
