Embodiment 1

[0016] A method for preparing a non-toxic fruit and vegetable detergent, comprising as raw material the bean curd pulp water discharged during the production process of soy products such as tofu, dried bean curd, and bean curd skin; it is characterized in that the preparation steps are: ①First, the bean curd pulp water is centrifuged at a high speed Centrifuge on the separator to remove the sediment and keep the supernatant spring water; ②Add a certain amount of alcohol to the supernatant slurry water, stir it thoroughly and then alcohol sink; ③Stay overnight, siphon the supernatant overnight, dissolve the sediment with a small amount of water, and then add A small amount of table salt, ethanol and sodium carboxymethyl cellulose are fully stirred and evenly spooned.

[0017] The tofu pulp water can be the fresh pulp water when producing soybean products, or the pulp water stored in cold storage.

[0018] The ethanol concentration when described ethanol alcohol precipitation is...

Abstract

The invention discloses a preparation method of a nontoxic fruit and vegetable washing agent, and belongs to the field of civil chemical technology. According to the preparation method, tofu slurry discharged in preparation process of tofu, dried bean curd, and thin sheets of bean curd is taken as a raw material; simple technology such as centrifugation and alcohol precipitation are adopted to obtain effective ingredients via separation; dissolving with a small amount of water is realized; appropriate amounts of table salt and carboxymethylcellulose sodium are added; and a finished product is obtained via uniform stirring. The nontoxic fruit and vegetable washing agent possesses following beneficial effects: the nontoxic fruit and vegetable washing agent can be used for removing pesticide residue on fruits and vegetables via washing, possesses excellent antibacterial and bacteria inhibition effect, and is nontoxic for human body and animals.

Description

technical field [0001] The invention relates to the technical field of civil chemical industry, in particular to a preparation method of a non-toxic fruit and vegetable detergent. Background technique [0002] Fruits and vegetables are inseparable from the spraying of pesticides in order to prevent pests and diseases in agricultural production. When people eat fruits with pesticide residues, it will affect their health, and seriously cause pesticide poisoning and induce cancer. Therefore, in order to ensure food safety, there is an urgent need for a detergent for removing pesticide residues. Most of the detergents sold on the market are chemical detergents synthesized from petroleum as raw materials. Although chemical detergents have removed pesticide residues from fruits and vegetables, But by the harm of chemical detergent. In order to protect people's health, a kind of washing agent which is harmless to the human body must be produced. [0003] In the production process...
