[0025] The preparation method of composite mercapto-containing microcapsules comprises the following steps:

[0026] (1) Mix mercaptobenzoic acid and N,N-dimethylformamide according to the mass ratio of 1:15~25, adjust the pH to 4.6~5.2 with HCl solution with a concentration of 0.1mol / L, protect with nitrogen, and use 300~ 450r / min magnetic stirring for 25~50min to get the premixed solution, take the premixed solution and add dopamine hydrochloride and N-hydroxysuccinimide at a mass ratio of 5~8:2~5:1 to mix, seal at room temperature and keep away from light for 6~8h , to obtain the pretreated product, take the pretreated chitosan solution and add the pretreated product in a mass ratio of 4~8:1~3 to mix, stir magnetically at 300~500r / min for 30~50min, and use NaOH solution with a concentration of 0.1mol / L Adjust the pH to 8.6~9.2, let stand for 8~12h, dialyze with 50% ethanol solution for 3~5 days, take the dialyzate and freeze-dry it at -60℃ to obtain the dried product;

Abstract

The invention relates to a fruit and vegetable washing agent, and belongs to the field of washing products. Thiosalicylic acid is matched with dopamine hydrochloride and pretreated chitosan liquid components to prepare a multiplex crosslinked product containing sulfydryl, a micro-sphere is prepared from the multiplex crosslinked product and enzymolysis bovine adrenal gland serum, epsilon-polylysine is matched with sodium citrate to prepare a composite micro-sphere. the heavy metal residue adsorption strength of a system can be enhanced, the prepared composite micro-sphere is easily eluted andconveniently used and cleaned, organic matters in the bovine adrenal gland serum can soften fruit and vegetable skins, pesticide components are conveniently cleaned, a composite auxiliary is preparedfrom sodium carbonate, glutathione, trimethyl citrate and the like serving as raw materials, functional group phosphate structures similar to pesticide residue components and the functional groups such as ammonium are provided, and dissolution of the pesticide residue components is facilitated. The fruit and vegetable washing agent solves the problem that many traditional cleaning agents cannot effectively remove fruit and vegetable residual pesticides and heavy metal pollution components at present.

Description

technical field [0001] The invention belongs to the field of washing products, in particular to a fruit and vegetable detergent. Background technique [0002] Most of the pesticide residues are concentrated on the surface of fruits and vegetables, and the pesticide residues can be effectively removed by peeling off the skin, but some nutrients of the fruits and vegetables will be lost, and this method is only suitable for fruits and vegetables with peels, and can only remove Pesticide residues on the surface of fruits and vegetables. For fruits and leafy vegetables, the current method commonly used in households to remove pesticide residues is soaking and washing. Although soaking and washing can dissolve and remove water-soluble pesticides, the removal efficiency is not high, and this method is not suitable for fat-soluble pesticides attached to the surface of fruits and vegetables. At this time, fruit and vegetable cleaning agents are needed to speed up the dissolution a...
