Description
Technical field
The present invention relates to food processing fields, and in particular to a kind of protein fruits and vegetables cleaning agent and preparation method thereof.
Background technique
In recent years, China's agricultural development was rapid, and the use scope of pesticide expands increasingly, usage amount in year by year it is increased become
Gesture.In order to improve the yield of fruits and vegetables and guarantee its yield and quality, will use in fruits and vegetables growth course fungicide and
Insecticide, common insecticide include organic phosphates, carbamates and quasi- chrysanthemum ester insecticide.In order to guarantee the peace of fruits and vegetables
Quan Xing, using suitable cleaning way to fruits and vegetables is essential step.Common fruits and vegetables cleaning agent has many limitations,
Most cleaning agents belong to the synthesis material based on cheap sodium alkyl benzene sulfonate, and safety is not high.Currently, most detergent institute
The surfactant contained may remain on fruit and vegetable surfaces, easily cause secondary pollution, and long-term intake may generate murder by poisoning to human body
Accumulation.
Patent of invention (application publication number: 102513055 B of CN, data of publication of application: 2013.08.14) is open to report topic
To be a kind of for adsorbing the magnetic material preparation method of enrichment organophosphorus pesticide, although organic phosphorus agriculture can be effectively made in this method
Medicine adsorbent material, but since the solution type of preparation is more, using a large amount of chemical raw material, certain pollution is caused to environment,
And this method requires high, complex procedures there are technique, it is at high cost the problems such as.Patent of invention (application publication number: CN
108841454 A, data of publication of application: 2018.11.20) preparation method for reporting a kind of entitled fruits and vegetables cleaning agent, the fruit are disclosed
Vegetable cleaning agent has good cleaning effect, but the raw material used is mostly chemical synthesis agent, can not only cause to environment centainly
Pollution, can also generate safety problem.Patent of invention (application publication number: 109225167 A of CN, data of publication of application:
2019.01.18 it) discloses and reports a kind of entitled pesticide in vegetable adsorbent, and the removal pesticide residue based on adsorption function
There are the defects such as time-consuming, and energy consumption is high, and adsorption efficiency is low in the adsorbent of vegetables processing method, this method preparation, make in face of promoting
Huge challenge.
Currently, detergent majority in the market is by components such as salt, surfactant or extracts, there are constituent phases
To the defects of single, pesticide residue rate is high, and safety is poor.Cerium ion has the ability of preferable degrading pesticide, and cerium ion is answered
For to there is significant realistic meaning in fruits and vegetables cleaning.It is low to develop a kind of green, mild, degradable, safety, pesticide residue rate
Fruits and vegetables cleaning agent, it is most important for reducing pesticide residue.
Summary of the invention
The object of the present invention is to provide it is a kind of using protein and cerium ion cooperation method, thus obtain it is a kind of can be effective
Adsorb the fruits and vegetables cleaning agent of pesticide.This method is simple and effective, does not need complicated and expensive equipment, and the raw material peace used
It is complete reliable, it is nontoxic, it is degradable, it is a kind of environmentally protective fruits and vegetables cleaning agent well.
The purpose of the present invention can be achieved through the following technical solutions:
