Food safety detection reagent and preparation method thereof

Abstract

The invention discloses a food safety detection reagent. The detection reagent comprises sodium cholate, polyoxyethylene lauryl ether, alpha-ketoglutaric acid, calcium oxalate, sodium citrate and a reductive metal salt solution, wherein the metal salt is a compound of one or more out of gold salts, silver salts and platinum salts; the gold salts are potassium chloraurate, sodium gold sulfite and gold sodium chloride; the silver salts are silver acetate, silver nitrate, silver citrate, silver carbonate and silver oxide; and the platinum salts are platinum tetrachloride, platinum bichloride andpotassium chloroplatinate. The detection reagent disclosed by the invention is capable of rapidly and simply detecting foods and is high in detection speed, high in sensitivity and intuitive and accurate in detection results. Moreover, the detection agent disclosed by the invention is simple in preparation method, low in cost and convenient to carry, does not need any special instrument or equipment or professional and is easy to popularize and implement.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a food safety detection reagent and a preparation method thereof. Background technique [0002] The issue of food safety has become a global topic, and vicious incidents of food safety continue to occur internationally, causing huge economic losses. Food safety issues mainly include the following aspects: chemical hazards, biological toxins, microbial hazards, food adulteration and safety issues of genetically engineered food. According to reports from the World Health Organization and the Center for Disease Control, 40% of food contamination incidents in Europe occur in individual households. In the United States alone, 76 million people suffer from foodborne illness and 5,000 die each year. In my country, microbial pollution, pesticide residues, pollution of water sources such as rivers, lakes and coastal waters, and illegal addition of hormones and drugs are important...
