Rapid extraction, purification and detection method for Sudan red dye residues in food

Abstract

The invention discloses a rapid extraction and purification device for Sudan red dye residues in food. The device comprises a frame body assembly, a rotating assembly, a mounting assembly, a connecting assembly, a compressing assembly, a liquid taking assembly and a filtering assembly. The invention discloses a method for rapidly extracting and detecting Sudan red dye residues in food, which comprises the following steps: performing component detection and analysis on extracted liquid through a Sudan red detector. Through mutual cooperation of the rotating structure and the filtering structure, food is automatically scraped and filtered, and Sudan red is dissolved. And through mutual cooperation of the concentration structure and the liquid taking structure, the extracting solution is concentrated, and automatic filling and sampling are carried out. The structural design is suitable for household use, and manual extraction by a user is not needed; thereby, the sampling is automatically completed, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of extraction and detection of Sudan Red, 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 dyeing agent, 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 harmful to the human body. The liver and kidney organs have obvious toxic effects. Sudan red belongs to the chemical dyeing agent, which is mainly used in petroleum, engine oil and some other industrial solvents. "Sudan", for the sake of food safety, many families need to sample and test Sudan Red in food. There are special detection instruments for Sudan Red detection, but the process of extracting Sudan Red from food is a bit complicated and the home operation is more troublesome. Therefore, We propose a rapi...
