preparation example Construction

[0024] A kind of preparation method of the depesticide fruit and vegetable cleaning agent based on shell powder, comprises the following steps:

[0025] Step 1, the preparation of micronano shell powder:

[0026] Wash the shells first, and then use the concentration of 0.3%-1% (such as 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, etc. or between any two) Hydrochloric acid solution or sodium hydroxide solution with a concentration of 0.5%-1% (such as 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, etc. or between any two) is used to treat the washed shells. Desalting and degreasing treatment to obtain shells after desalting and degreasing; the desalting and degreasing treatment is: soak the cleaned shells with the above-mentioned hydrochloric acid solution or sodium hydroxide solution for 30-60 minutes (for example, in 30 minutes, 40 minutes, 50 minutes, 55 minutes, 60 minutes, etc.) or between any two), preferably 45min; the shell is one or more of mussels, scallops, oyster shells, river ...

Embodiment 1

[0042] In the pesticide-free fruit and vegetable cleaning agent of this embodiment, the weight percentage of the micro-nano shell powder in the pesticide-free fruit and vegetable cleaning agent is 90%.

[0043] (1), first wash the shells, and then use a 0.4% hydrochloric acid solution or a 0.6% sodium hydroxide solution to desalt and degrease the washed shells: soak for 45 minutes to obtain the desalted and degreased shells, Drying or drying to obtain dried shells; the shells are one of mussels, scallops, oyster shells, river clam shells, flower carapaces, etc., preferably mussels;

[0044] (2), then the dried shells are coarsely pulverized by a pulverizer to obtain a coarse shell powder with a particle size of 1 mm;

[0045] (3) Carry out high-temperature calcining and puffing treatment on the coarse shell powder in a high-temperature resistance furnace or a muffle furnace at 700° C. to obtain a calcined coarse powder; then cool it to obtain a cooled coarse powder;

[0046] ...

Embodiment 2

[0055] In the pesticide-free fruit and vegetable cleaning agent of this embodiment, the weight percentage of the micro-nano shell powder in the pesticide-free fruit and vegetable cleaning agent is 88%.

[0056] (1), first wash the shells, and then use a 0.7% hydrochloric acid solution or a 0.8% sodium hydroxide solution to desalt and degrease the washed shells: soak for 50 minutes to obtain the desalted and degreased shells, Drying or drying to obtain dried shells; the shells are one of mussels, scallops, oyster shells, river clam shells, flower carapaces, etc., preferably oyster shells;

[0057] (2), then the dried shells are coarsely pulverized by a pulverizer to obtain a coarse shell powder with a particle size of 0.2 mm;

[0058] (3) Carry out high-temperature calcining and puffing treatment on the coarse shell powder at 900° C. in a high-temperature resistance furnace or a muffle furnace to obtain a calcined coarse powder; then cool it to obtain a cooled coarse powder;

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 [0001] The invention belongs to the field of detergent compositions, in particular to a preparation method of a shell powder-based de-pesticide fruit and vegetable cleaning agent. Background technique [0002] Fruits and vegetables are indispensable food in people's daily life. In order to increase the yield of fruits and vegetables and ensure their quality, a large amount of pesticides for eliminating diseases and insect pests are often sprayed during the growth of fruits and vegetables, resulting in some pesticides remaining on the surface of commercially available fruits and vegetables . And pesticides are difficult to remove by washing with water. At present, in daily life, the products available for cleaning the surface of fruits and vegetables include dishwashing liquid and fruit and vegetable detergents prepared from some vegetable oils. However, most of the dishwashing liquids currently available on the market are chemical synthetic products. And th...
