Food residual formaldehyde cleaning agent and preparation method thereof

Abstract

The invention discloses a food residual formaldehyde cleaning agent which comprises the following components in parts by weight: 10-15 parts of polyacrylamide, 3-5 parts of hydrazine hydrate, 10-15 parts of methanol, 3-5 parts of propionyl hydrazine, 3-5 parts of urea and 2-3 parts of a blueberry extract. A preparation method of the food residual formaldehyde cleaning agent comprises the followingsteps of: A1, preparing the blueberry extract; A2, preparing an acryloyl hydrazine high-molecular compound; and A3, synthesizing the cleaning agent. Blueberry fruits contain a large amount of activesubstances such as flavone, polyphenol and anthocyanin and have high antioxidant activity; polyphenol and flavonoid compounds have wide biological activities such as oxidation resistance, free radicalscavenging, cancer resistance, bacterium resistance, virus resistance and inflammation resistance; and residual formaldehyde in food can be effectively removed by adding the blueberry extract.

Description

technical field [0001] The invention mainly relates to the technical field of food safety, in particular to a food residue formaldehyde cleaning agent and a preparation method thereof. Background technique [0002] In recent years, food safety has attracted increasing attention, and food pollutants are the direct factors leading to food safety incidents. The impact of formaldehyde on human health is widely recognized by people. With the improvement of people's consumption level, the consumption of food has also increased significantly, which indirectly caused the occurrence of illegal formaldehyde addition incidents. Formaldehyde is mostly used in industrial raw materials, and some unscrupulous merchants illegally add formaldehyde to aquatic products in order to prolong the shelf life of aquatic products and prevent products from rotting. Therefore, China has banned the use of formaldehyde to soak aquatic products. The U.S. Environmental Protection Agency stipulates that ...
