[0002] Food refers to various finished products and raw materials for human consumption or drinking, as well as items that are both food and traditional Chinese medicinal materials according to tradition. In modern society, in order to enhance the taste of food or extend its shelf life, food additives are used in the production process of food. The safe use of food additives is very important. Most food additives, especially chemically synthesized ones, have certain toxicity. Therefore, the amount of use needs to be strictly controlled. Thus, it is necessary to detect food additives in the food put on the market to ensure people's food health. Currently, chromatographic analysis methods are usually used for the detection of food additives. For example, liquid chromatography is used to analyze and detect food. When using liquid chromatography to detect food, the liquid sample to be detected is injected into the chromatographic column and moves in the stationary phase through pressure. Since different substances in the sample to be detected have different interactions with the stationary phase, different substances leave the chromatographic column in sequence, and different peak signals are obtained through the detector. Finally, these signals are analyzed and compared to determine the substances contained in the sample to be detected.

[0003] Before using liquid chromatography to detect food, it is necessary to prepare the food into a liquid sample to be detected through a sample treatment step. Currently, the sample treatment process and the detection process of the food additive detection device are separated, so that sample treatment needs to be carried out additionally during the detection process, thus affecting the efficiency of food detection.
