Problems solved by technology

Commonly used fruit and vegetable cleaning agents have many limitations. Most of the cleaning agents are synthetic raw materials based on cheap sodium alkylbenzene sulfonate, and their safety is not high.
At present, the surfactants contained in most detergents may remain on the surface of fruits and vegetables, easily causing secondary pollution, and long-term intake may cause toxic accumulation to the human body
[0003] Invention patent (application publication number: CN 102513055 B, application publication date: 2013.08.14) publicly reported a method for preparing magnetic materials for adsorption and enrichment of organophosphorus pesticides, although this method can effectively prepare organophosphorus Pesticide adsorption materials, but due to the preparation of many types of solutions, a large amount of chemical raw materials are used, which causes certain pollution to the environment, and this method has problems such as high process requirements, complicated procedures, and high costs.
Invention patent (application publication number: CN108841454 A, application publication date: 2018.11.20) publicly reported a preparation method titled a fruit and vegetable cleaning agent. The fruit and vegetable cleaning agent has a good cleaning effect, but most of the raw materials used are chemically synthesized The use of agents will not only cause certain pollution to the environment, but also cause safety problems.
Invention patent (application publication number: CN 109225167 A, application publication date: 2019.01.18) publicly reported a vegetable pesticide adsorbent and a vegetable treatment method based on adsorption function to remove pesticide residues. The adsorbent prepared by this method There are defects such as long time consumption, high energy consumption, and low adsorption efficiency, and face huge challenges in popularization and use
[0004] At present, most of the detergents on the market are composed of salt, surfactants or extracts, etc., which have defects such as relatively single composition, high pesticide residue rate, and poor safety.

Embodiment 1

[0025] Accurately weigh 8g of peanut protein, put it into a beaker, add 100ml of distilled water to stir, use 0.1M hydrochloric acid to adjust the pH of the solution to 9.0 to fully dissolve the peanut protein, add 8g of cerium ammonium nitrate to dissolve in the protein solution, and heat it in a water bath to 40°C. Perform magnetic stirring, and adjust the reaction pH to 6.0, and the reaction time is 18h. The peanut protein-cerium complex was washed once with a mixed solution of acetone / ethanol (1:1). After cleaning, it was centrifuged in a centrifuge at a speed of 4000 r / min for 10 min. The supernatant was removed, and the lower layer was removed for later use. Then, the obtained precipitate was washed twice with deionized water to remove residual acetone and ethanol in the precipitate. The supernatant was removed by centrifugation, and the lower precipitate was freeze-dried for later use. The centrifuge speed was 4000r / min, and the centrifugation time was 10min. Take drie...

Description

technical field [0001] The invention relates to the field of food processing, in particular to a protein fruit and vegetable cleaning agent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's agriculture, the scope of use of pesticides is expanding day by day, and the amount of use is increasing year by year. In order to increase the yield of fruits and vegetables and ensure their yield and quality, fungicides and insecticides are used during the growth of fruits and vegetables. Commonly used insecticides include organophosphorus, carbamate and pyrethroid insecticides . In order to ensure the safety of fruits and vegetables, it is an essential step to adopt appropriate cleaning methods for fruits and vegetables. Commonly used cleaning agents for fruits and vegetables have many limitations. Most cleaning agents are synthetic raw materials based on cheap sodium alkylbenzene sulfonate, and their safety is...
