Technical Field
[0001] The utility model relates to the technical field of food detection, in particular to a food fluorescence detection kit. Background Art
[0002] A food fluorescence detection kit is a kit used for rapid detection of specific ingredients or contaminants in food. In order to ensure people’s food safety, it is usually necessary to inspect and analyze food. Among them, food fluorescence detection is a more common inspection method in food inspection.
[0003] The existing food fluorescence detection kit is mainly composed of a box body, a reagent placement cavity and a fluorescent marker. Its working principle is through fluorescence analysis technology. When the food sample to be tested is mixed with the reagent in the kit and reacts under appropriate conditions, the target substance will combine with the fluorescent marker or undergo other specific chemical reactions to generate fluorescent signals. These fluorescent signals can be captured by the fluorescence detector and converted into electrical signals, which are then analyzed by the data processing system to obtain the content or presence of the target substance in the sample.
[0004] The existing test kit needs to be mixed with experimental reagents repeatedly during use. During the mixing and shaking process, it is easy to cause leakage and contaminants are easily mixed in, affecting the detection effect. At the same time, the test results will also be affected by the uneven proportion of reagent addition during the mixing process. Therefore, a food fluorescence detection kit is proposed to address the above problems. Utility Model Content
