preparation example Construction

[0032] The preparation method of a kind of natural fruit and vegetable cleaning powder of the present invention, its principle is: the calcined eggshell powder, rice bran powder, bamboo charcoal powder are mixed and compounded, and the characteristic of above-mentioned three kinds of materials is brought into full play, namely calcined eggshell powder decomposes pesticide, rice bran powder Adsorbing pesticides and heavy metals, bamboo charcoal has the characteristics of adsorbing organophosphorus pesticides and heavy metal complexes, so as to achieve the purpose of safely, efficiently and quickly removing pesticide residues, pathogenic bacteria and heavy metals on the surface of fruits and vegetables.

[0033] 1. Determination of eggshell calcination temperature

[0034] Eggshell is a natural biomineralized material rich in calcium carbonate (over 95%). Eggshells have a loose and porous structure. Previous studies have shown that eggshells have certain adsorption properties fo...

Embodiment 1

[0070] Collect the discarded eggshells, wash them with tap water, and then send them to an oven for drying at a constant temperature of 110°C, so that the inner and outer surfaces of the eggshells are dry, crush them into shell powder, and send them to the ashing furnace in batches. Calcined at 400°C for 60 minutes, fixed temperature at 800°C / calcined for 60 minutes, eggshell ash powder with different whiteness can be obtained after calcined, and the products of the two calcined processes are compounded at a ratio of 4:6, and then the The ratio of eggshell powder: rice bran powder: bamboo charcoal powder is 80%: 10%: 10%, after mixing evenly, micro-nano crushing is made into fruit and vegetable cleaning powder products.

[0071] Take 1g of fruit and vegetable cleaning powder, add 1L of water, and prepare a solution. Soak 300g of grapes in the solution for 20 minutes, take it out and rinse with water. Take 2g of grape skins and use the pesticide residue detection kit to detect...

Embodiment 2

[0073] Collect the discarded eggshells, wash them with tap water, and then send them to an oven for drying at a constant temperature of 110°C, so that the inner and outer surfaces of the eggshells are dry, crush them into shell powder, and send them to the ashing furnace in batches. Calcined at 500°C for 60 minutes, fixed temperature at 900°C / calcined for 60 minutes, eggshell ash powder with different whiteness can be obtained after calcined, the products of the two calcined processes are compounded at a ratio of 3:7, and the Eggshell powder: rice bran powder: bamboo charcoal powder is 75%: 20%: 5% after mixing evenly, micro-nano crushing to make fruit and vegetable cleaning powder products.

[0074] Take 0.6g of fruit and vegetable cleaning powder, add 1L of water, and prepare a solution. Soak 2 apples in the solution for 30 minutes, take them out and rinse them with clean water. Take 5g of apple peel, and use the pesticide residue detection kit to detect the pesticide resid...

Abstract

The invention discloses natural fruit and vegetable cleaning powder. The natural fruit and vegetable cleaning powder comprises egg shell powder, rice bran and bamboo charcoal. Egg shells are calcined at the temperature of 300-500 DEG C and the temperature of 700-900 DEG C to obtain first calcined products and second calcined products, the first calcined products and the second calcined products are compounded to obtain the egg white powder, and the rice bran is a rice processing byproduct. The natural fruit and vegetable cleaning powder has the advantages that the natural fruit and vegetable cleaning powder is environmentally friendly, is safe and is low in energy consumption, seashells in the prior art are replaced by the egg shells, the egg shells can come from wide sources, and the calcination temperatures are reduced from the original 900-1500 DEG C and are lower than 900 DEG C; low-temperature activation technologies and high-temperature calcination technologies for the egg shells are combined with one another, accordingly, the natural fruit and vegetable cleaning powder is low in energy consumption, and effects superior to effects of direct high-temperature calcination in the prior art can be realized; the rice bran and the bamboo charcoal are added into the natural fruit and vegetable cleaning powder, accordingly, effects of products can be enhanced, the pesticide clearance rate can reach 99%, the pathogenic bacterium clearance rate can reach 100%, diversified effects of quickly removing pesticides, bacteria and oil stain and adsorbing heavy metal can be realized by the natural fruit and vegetable cleaning powder, the natural fruit and vegetable cleaning powder is made of natural sources and is low in cost and easy to popularize, and waste materials can be recycled.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable cleaning powder compositions, in particular to a natural fruit and vegetable cleaning powder and a preparation method thereof. Background technique [0002] Most of the existing fruit and vegetable cleaners are chemically synthesized, although the decontamination ability is strong, but because the chemically synthesized products are not easy to degrade, they have an impact on the environment, and their secondary cleaning is also difficult to complete. If they are used for a long time, they will easily cause harm to the human body. . [0003] According to the technical report of the existing green cleaning agents, high-temperature calcined shells are mostly used as fruit and vegetable cleaners. However, due to serious marine pollution in recent years, heavy metal ions are deposited in marine organisms, and heavy metal residues exist in the use of calcined shells for cleaning fruits and ...
