Abstract

The invention discloses a rapid extraction purification and detection method for Sudan red dye residue in food. The rapid extraction purification and detection method comprises the following steps: collecting a sample: an experimenter wears gloves to take out all articles in a package, vegetables to be detected such as chili can be firstly prepared, the surface layer of the vegetable can be cleaned by using little water, the cleaned water is collected for standing, then the surface layer of the vegetables such as the chili is scraped, and then little flesh inside the vegetables such as chili is collected and placed in a number-one empty reagent tube. The invention relates to the technical field of food safety detection. According to the rapid extraction purification and detection method for the Sudan red dye residue in food, by virtue of the cooperation of a detection tool and chemicals in a detection apparatus, a whole detection process can be operated by an ordinary person, so that the food bought at normal times can be detected by the ordinary person at home with the detection tool without using a professional detection mechanism, the use is convenient, the supervision of publicpeople for the food can be facilitated, and the food supervision can be improved.

Description

technical field [0001] The invention relates to the technical field of food safety detection, in particular to a method for rapid extraction, purification and detection of Sudan red dye residue in food. Background technique [0002] "Sudan Red" is a chemical dye, not a food additive. Its chemical composition contains a compound called naphthalene, which has an azo structure. Due to the nature of this chemical structure, it is carcinogenic and has obvious toxic effects on the liver and kidney organs of the human body. Sudan red is a chemical dyeing agent, mainly used in petroleum, engine oil and some other industrial solvents, the purpose is to make it more colorful, and it is also used to add luster to shoes and floors. Also known as "Sudan". Sudan red is a lipophilic azo dye, mainly used for dyeing oil paint, engine oil, wax and shoe polish. Because the color of food dyed with Sudan red is very bright and not easy to fade, it can arouse people's strong appetite. Some ill...
