Abstract
The invention belongs to the field of detergent compositions, and provides a method for preparing a pesticide-removing fruit and vegetable cleaning agent based on shell powder. The pesticide-removing fruit and vegetable cleaning agent is prepared from natural shell powder as a main raw material, and a natural adjuvant by the steps of preparation of micro/nano shell powder and addition of the natural adjuvant. The pesticide-removing fruit and vegetable cleaning agent is capable of effectively adsorbing and removing harmful residue matters such as pesticides and chemical fertilizers in the fruits and vegetables, not changing the properties of foods, and prolonging the quality guarantee period, and is safe, non-toxic, degradable, and suitable for cleaning of various fruits and vegetables; and the fruits and vegetables can be directly eaten after being cleaned. The pesticide-removing fruit and vegetable cleaning agent has good adsorptive property, bactericidal performance and the like, can play a good adsorption role in pesticide residues on the surfaces of the fruits and vegetables, is free of harm to a human body and the environment, and is capable of overcoming the defects of an existing cleaning agent in the aspects of non-degradation and chemical synthetic substance residue on the surfaces of the fruits and vegetables.
Description
Technical field
The invention belongs to detergent composition field, particularly a kind of preparation method of the de-agricultural chemicals fruit-vegetable clear lotion based on shell powder.
Background technology
Fruit and vegetable be in people's daily life every day requisite food, in order to improve the output of fruits and vegetables and ensure its quality, in the process of growth of fruits and vegetables, often spray a large amount of agricultural chemicals except disease and pest, thus cause commercially available fruit and vegetable surfaces still lingering section agricultural chemicals.And agricultural chemicals is difficult to rinse with clear water remove.In current daily life, the fruits and vegetables washing composition that cleaning fruit and vegetable surfaces enabled production has liquid detergent and some plant wet goods to prepare, and current commercially available liquid detergent is mostly chemical industry sintetics, washing thoroughly can not cause fruit and vegetable surfaces to remain, and to HUMAN HEALTH and environment all unfavorable, some natural fruit and vegetables washing composition become major part for lipid acid, can cause the eutrophication of environment.In prior art, be badly in need of a kind of effective, green natural degradable fruit-vegetable clear lotion to make up the deficiency of existing fruits and vegetables washing composition.
Disclose a kind of micro-nano health environment-friendly based on Living marine resources in Chinese patent application (application number 201310755562) and wash clean goods, this Cleaning preparations with waste shell micro-nano framework material for carrier, auxiliaryly join marine algae active substance, biological activity catalyzer and deionized water, by certain proportioning at a suitable temperature, undertaken formulated by the technique optimized.This raw material washed in clean goods also will use seaweeds active substance, biological activity catalyzer, and raw material not easily obtains, and cost is higher, and limited to the degradation effect of the pesticide residue of fruits and vegetables.
Chinese patent application (application number: disclose a kind of natural cleaning agent for removing fruit and vegetable surfaces remains of pesticide 201110349332.7), this clean-out system is by cleaning, sterilization, high temperature dot solution, ionization shell and form pressed powder, refine with mesh screen the nanometer powder that is made, this clean-out system is combined according to a certain weight ratio by one or more natural seashells thereafter.The raw material of this clean-out system is comparatively single, and also very limited to the degradation effect of the pesticide residue of fruits and vegetables.
Because at natural fruit and vegetables detergent applications, need that a kind of main raw material is shell powder, excellent to garden stuff pesticide residue degradation effect natural fruit and vegetables washing composition.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of preparation method of the de-agricultural chemicals fruit-vegetable clear lotion based on shell powder, this fruits and vegetables washing composition garden stuff pesticide residue degradation effect is excellent.
The object of the invention is to be achieved through the following technical solutions:
Based on a preparation method for the de-agricultural chemicals fruit-vegetable clear lotion of shell powder, comprise the following steps:
The preparation process of micro-nano shell powder: shell is carried out desalination skimming treatment, drying treatment, coarse reduction process, calcining puffing, cooling process, micro-nano pulverization process, obtain described micro-nano shell powder;
Natural promoter adds step: in described micro-nano shell powder, add natural promoter, obtain described de-agricultural chemicals fruit-vegetable clear lotion;
Further, the weight percent that described micro-nano shell powder accounts for de-agricultural chemicals fruit-vegetable clear lotion is 80-95%, is preferably 85-90%;
Further, described shell is one or more mixing in mussel, scallop, oyster shells, Corbicula fluminea shell, cycle of sixty years shell;
Further, in described desalination skimming treatment, hydrochloric acid soln or sodium hydroxide solution is adopted to soak;
Further, the temperature 500-1200 DEG C of calcining puffing, is preferably 600-1000 DEG C;
Further, the particle diameter of described micro-nano shell powder is 50nm-1000nm, is preferably 100-500nm.
Further, described natural washing auxiliary agent is any one or a few the combination in Starso, sodium carbonate, Trisodium Citrate, Whitfield's ointment, citric acid etc.;
Further, the pH value of described de-agricultural chemicals fruit-vegetable clear lotion is 7-12;
The de-agricultural chemicals fruit-vegetable clear lotion that the preparation method of the described de-agricultural chemicals fruit-vegetable clear lotion based on shell powder obtains, using method is: by described de-agricultural chemicals fruit-vegetable clear lotion in mass ratio (0.1-1.5): 1000 drop in water, for cleaning fruits and vegetables after dispersed.
The present invention has following beneficial effect compared to existing technology:
1, because the present invention adopts natural seashell powder as main raw material, add with natural promoter, so energy active adsorption, the hazard residue material such as agricultural chemicals, chemical fertilizer removed in fruits and vegetables, and do not change food nature, can also extend the shelf life, safety non-toxic, degradable, direct-edible after cleaning, be applicable to the cleaning of various gourd, fruit and vegetable.
2, because the present invention adopts natural seashell powder as main raw material, so can be scattered in clear water very soon, there is good absorption agricultural chemicals and sterilization fresh-keeping performance, good washability is had to fruits and vegetables, and product is natural harmless, degradable is that the very promising pure natural of one takes off agricultural chemicals fruit-vegetable clear lotion.
3, because various raw material rational proportion of the present invention, so have the function such as good adsorption properties and bactericidal property simultaneously, good adsorption can be had to the pesticide residue of fruit and vegetable surfaces, and to human body and environment all harmless; Not being degraded existing for existing clean-out system, defect that chemical industry synthetic remains in the aspects such as fruit and vegetable surfaces can be overcome.
4, raw material sources of the present invention are extensive, and preparation method is simple, is suitable for promoting the use of.
