Immune chromatographic paper strip and method for quick detecting pathogen and toxin in food

Abstract

The present invention discloses a kind of immunogical chromatographic paper strip for sensitive, specific and fast detection of common pathogen and toxin in food and the detection method. The present invention is the new technology for detecting pathogen and toxin in food and its application. Now, there are great amount of reports on applying colloidal gold immunogical chromatographic test paper in detecting soluble antigen and bacteria as granular antigen are detected after being treated via extraction or other processes. The present invention features that special chromatographic film and optimized conditions are adopted so that the immunogical chromatographic paper strip may be used directly in detecting bacteria. The present invention may be used in the fast detection of common pathogen in food and the fast diagnosis of toxin in food.

Description

technical field

[0001] The present invention relates to the rapid detection of common pathogenic bacteria or toxins in food, more specifically, it relates to an immune paper chromatography strip and its detection method for rapidly detecting common pathogenic bacteria or toxins in food by using colloidal gold and immune chromatography technology . Background technique

[0002] "Food is paramount to the people." Human beings cannot live without food. Food is one of the most important commodities in any society's economy. Therefore, the problem of food safety is concerned by millions of people. But the current food safety problem is not optimistic. In today's world, disease due to contaminated food is a significant contributor to declining living standards, declining health and economic productivity. Food poisoning has become one of the most common social, economic and environmental problems. According to statistics, in 1980 alone, in developin...
