Embodiment 1

[0032] A detergent, comprising the following components in mass percentage: 35wt% of β-cyclodextrin, 2wt% of sodium chloride, 2wt% of sodium stearate, 0.5wt% of citric acid, 4wt% of sodium cellulose, and the balance is water .

[0033] The preparation method of the detergent is as follows: dissolve 2g of sodium stearate in 56.5g of water and stir evenly, then add 2g of sodium chloride and 35g of β-cyclodextrin into the solution, and stir until sodium chloride and β-cyclodextrin are mixed at room temperature. The cyclodextrin was completely dissolved, and then 4 g of sodium cellulose was added to the solution in batches, and finally 0.5 g of citric acid was added to adjust the pH value of the solution to obtain the final detergent.

Embodiment 2

[0035] A detergent comprises the following components in mass percentage: 25 wt% of beta-cyclodextrin, 1 wt% of sodium chloride, 1 wt% of sodium stearate, 5 wt% of sodium alginate, and the balance is water.

[0036] The preparation method of the detergent is: dissolve 1g of sodium stearate in 68g of water and stir evenly, then add 1g of sodium chloride and 25g of β-cyclodextrin into the solution, and stir at room temperature until the sodium chloride and β-cyclodextrin The dextrin is completely dissolved, and then 5 g of sodium cellulose is added to the solution in batches, and stirred evenly to obtain the final detergent.

Embodiment 3

[0038] A detergent comprising the following components by mass percentage: α-cyclodextrin 50wt%, sodium chloride 3wt%, sodium palmitate 1wt%, sodium bicarbonate 1wt%, cellulose sodium 3wt%, and the balance is water .

[0039] The preparation method of the detergent is: dissolve 1g of sodium stearate in 42g of water and stir evenly, then add 3g of sodium chloride and 50g of α-cyclodextrin into the solution, and stir at room temperature until the sodium chloride and α-cyclodextrin The dextrin is completely dissolved, then 3 g of sodium cellulose is added to the solution in batches, and finally 1 g of sodium bicarbonate is added to adjust the pH value of the solution to obtain the final detergent.

Abstract

The invention discloses a detergent and application thereof to fruit and vegetable washing. The detergent is composed of, by weight percentage, 25-50 wt% of inclusion agent, 1-3 wt% of stabilizer, 1-3 wt% of dispersing agent, 0-1 wt% of pH regulator, 3-5 wt% of thickener and water as balance. The detergent can achieve good washing effects on fruits and vegetables, through chemical bonding effects, can adsorb pesticide residues on the surface of the fruits and vegetables into the hydrophobic cavities of cyclodextrin, and by means of the hydrophilic surface of the cyclodextrin, can dissolve a large quantity of pesticides into water to achieve the aim of efficiently removing the residues of pesticides, preservatives, plant growth promoters and the like on the surface of the fruits and vegetables. The detergent can effectively solve the problems of secondary washing incompleteness and secondary pollution during fruit washing with existing detergents.

Description

technical field [0001] The invention belongs to the technical field of washing products, and in particular relates to a washing agent and its application in cleaning fruits and vegetables. Background technique [0002] In order to prevent crops such as fruits and vegetables from being affected by insect pests during the growth process, pesticides such as insecticides are often used to control them. Some farmers ignore the safety interval of pesticides and the relevant regulations on the use of pesticides because they are eager to make profits, and use excessive amounts. Therefore, pesticide residues on fruits and vegetables are inevitable. Since most of the fruits and vegetables are eaten fresh, the residual pesticides adsorbed on the fruits and vegetables have caused serious harm to the human body. According to statistics, the residual pesticides ingested by humans through eating fruits and vegetables account for more than 55% of the total. In China, the residual pesticid...
