Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of food detection accessory devices, and in particular to a combined detection card assembly for food detection. Background Art
[0002] Food safety is a global concern. Microorganisms, chemical contaminants and allergens that may exist in food pose a serious threat to human health. Traditional food testing methods usually rely on laboratory equipment, such as high performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), etc. Although these methods are highly accurate, they have disadvantages such as high cost, long testing cycle, and complex operation, making it difficult to achieve rapid on-site testing.
[0003] In recent years, rapid detection technologies have been developed rapidly to improve the efficiency and convenience of food safety testing. Among them, enzyme-linked immunosorbent assay (ELISA) based on immunological principles, colloidal gold immunochromatography (ICA), and biosensor-based detection methods are widely used. These technologies can give preliminary test results in a short time through specific antigen-antibody reactions, which are suitable for on-site screening. Although the existing rapid detection technology can meet a certain degree of on-site detection needs, there are still some limitations in practical applications. For example, a single test card can often only detect one or a few targets. For complex food samples, multiple test cards may be required, which not only increases the detection cost, but may also lead to inconsistent test results due to improper operation. In addition, traditional test cards are easily affected by environmental factors during storage, transportation and use, which reduces the accuracy of detection and thus has poor practicality.
