Problems solved by technology

Calcium hydroxide obtained from natural shells and limestone calcined at high temperature can desorb and degrade pesticide residues on the surface of fruits and vegetables, but has the following defects: strong alkalinity, pH value is often greater than 12, and has a certain effect on the oil on the skin surface. Dissolution, so some people with dry skin may experience mild skin wrinkling and dry skin
Aflatoxin is insoluble in water, so it cannot be effectively removed by washing with water

Embodiment 1

[0022] 500 grams of oyster shells and 160 grams of magnesium carbonate were pulverized and mixed, calcined for 1.5 hours at a temperature of 780° C., cooled to room temperature to obtain 210 grams of calcined material, and the calcined material was placed in a slurry tank, and 400 grams of deionized water was added. Stir for 1 hour, then add 6 grams of chitin, 12 grams of magnesium chloride, 3 grams of citric acid, 14 grams of sodium citrate, and 10.5 grams of sodium dihydrogen phosphate, ball mill, pass through a 1250-mesh sieve, and spray dry.

Embodiment 2

[0024] 500 grams of scallop shells and 120 grams of magnesium carbonate were pulverized and mixed, calcined for 1.2 hours at a temperature of 820° C., cooled to room temperature to obtain 174 grams of calcined material, and the calcined material was placed in a slurry tank, and 360 grams of deionized water was added. Stir for 1 hour, then add 8.4 grams of chitin, 1.8 grams of magnesium chloride, 12.5 grams of citric acid, 4.2 grams of sodium citrate, and 9.2 grams of sodium dihydrogen phosphate, ball mill, pass through a 1250-mesh sieve, and spray dry.

Embodiment 3

[0026] 500 grams of mussel shells and 80 grams of magnesium oxide were pulverized and mixed, calcined for 0.5 hour at a temperature of 850° C., cooled to room temperature to obtain 168 grams of calcined material, and the calcined material was placed in a slurry tank, and 270 grams of deionized water was added. Stir for 0.5 hours, then add 3.5 grams of chitin, 14 grams of magnesium chloride, 1.8 grams of citric acid, 8 grams of sodium citrate, and 13.2 grams of sodium dihydrogen phosphate, ball mill, pass through a 1250-mesh sieve, and spray dry.

Abstract

The embodiment of the invention discloses a cleaning agent capable of effectively removing pesticide residues, aflatoxins and harmful bacteria, which belongs to the technical field of cleaning agents. The cleaning agent is prepared by using shells as the main material, adding magnesium-containing substances, successively crushing and mixing, calcining, and deionized water treatment, adding buffer additives, ball milling, sieving, and drying. The present invention can reduce and control the alkalinity by adding magnesium-containing reagents before calcining shells, and adding buffering aids with a buffering effect after calcining, so that the pH value can be reduced to 10-11.5, which can reduce the effect of calcium hydroxide aqueous solution on the skin. Stimulate.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of cleaning agents, in particular to a cleaning agent capable of effectively removing pesticide residues, aflatoxins and harmful bacteria. Background technique [0002] Pesticides are widely used in the process of planting fruits and vegetables, and pesticides that are not fully degraded remain on the surface of fruits and vegetables, endangering people's food safety. Common pesticide removal methods include direct rinsing with water, or cleaning with various chemical synthetic detergents. Due to the poor water solubility of most pesticides, clean water can only effectively remove the dirt and dust on the surface of fruits and vegetables, but harmful substances such as pesticides and bacteria cannot be removed. Chemical synthetic detergents mainly rely on the decontamination ability of surfactants and need to be in full contact with pesticides. It is difficult to remove pesticide r...
