example 1

[0017] Weigh 100g of rice, wash it with deionized water twice, collect the washed rice water and the washed rice, add 500mL of deionized water to the iron pot and heat it to boiling, then add the washed rice After 20 minutes of heat preservation and boiling, stop heating, place the material in the iron pot to grind for 30 minutes in a stone mill, collect the grinded slurry, and filter to obtain the filtrate. After mixing the filtrate with the rice washing water, the mixture is obtained. Weigh 300g of tea tree branches and rinse the surface of the branches with deionized water for 3 times. Place them in an oven and dry them at 95°C to a moisture content of 20%. Place the dried tea tree branches in a pulverizer for 30 minutes to get crushed. Add the pulverized product to a beaker containing 500 mL of absolute ethanol, and then place it in an ultrasonic oscillator for ultrasonic extraction for 3 hours. After the extraction is completed, the extract is collected; the above extract i...

Abstract

The invention relates to a preparation method of a natural composite fruit and vegetable cleaning agent, and belongs to the technical field of fruit and vegetable cleaning agents. The method comprises the following steps: firstly, washing and boiling out the rice, wherein the alkaline substances in the rice washing water are allowed to react with harmful substances in the pesticide, so that the pesticide loses toxicity, the starch and the polysaccharide in the rice pulp can effectively dissolve oil stains and impurities on the surface of the fruits and vegetables; extracting tea tree oil from tea tree branches, wherein the fat-soluble small molecules in the tea tree oil are utilized to permeate into the surface layer of the fruits and vegetables, so as to dissolve the pesticide on the surface layer and the surface; subjecting shell to alkali activation and high-temperature firing, wherein the shell powder has strong adsorption and alkaline sterilization action and can decompose residual pesticide, fruit wax and impurities on the surface of the fruits and vegetables. The fruit and vegetable cleaning agent disclosed by the invention solves the problem that the existing fruit and vegetable cleaning agent cannot effectively clean residual impurities, oil stain and pesticide on fruits and vegetables and is easy to remain after the fruits and vegetables are cleaned and secondary pollution is caused; and the removal rate of the fruit and vegetable cleaning agent can reach 98.6%-99.3%, the original flavor of the fruits is not changed, and the fresh-keeping period can be prolonged by 10-15 days.

Description

Technical field [0001] The invention relates to a preparation method of a natural composite fruit and vegetable cleaning agent, belonging to the technical field of fruit and vegetable cleaning agent preparation. Background technique [0002] Nowadays, science and technology are becoming more and more advanced, people's lives are becoming more and more convenient, and various diseases are increasing day by day. Among them, food safety is the top priority for people's health and social stability. At present, the daily intake of various pesticides in the daily diet of Chinese residents is dozens of times that of developed countries such as the United States, Japan, and the European Union. According to the monitoring of the Ministry of Agriculture, the total detection rate of pesticides in fruits and vegetables is 32%, the total exceeding rate The rate of pesticide residues in vegetables in 6 major cities including Beijing exceeds 50%. Solving the problem of pesticide residues has b...
