Abstract
In this paper, the latest research results and practical application of western blot technology in the field of food allergen detection were discussed. In view of the increasingly serious problem of food allergy, accurate and efficient detection of allergens in food has become an important task to ensure public health. Western blot technology, with its excellent sensitivity, specificity and multi-component detection capabilities, has shown significant advantages in the detection of food allergens. In this paper, the basic principle of western blot technology was systematically described, including sample pretreatment, effective protein separation, transfer fixation, immune response and subsequent accurate detection. Further, the strategies of western blotting to improve the sensitivity and specificity of detection, such as optimizing antibody selection and reducing cross-reactivity, were analyzed in detail. The technical challenges and solutions for simultaneous detection of multi-component allergens were discussed, including efficient separation technology, antibody array design, etc. The application of western blotting in quantitative and semi-quantitative analysis and its recent progress in standardization process and quality control are also introduced. In addition, this paper also looks forward to the potential of western blotting in the discovery and study of novel allergens, including the combined application of genomics and western blotting technology to accelerate the identification and validation of novel allergens. In summary, this paper not only summarizes the current achievements of immunoblotting technology in the detection of food allergens, but also looks forward to its future development direction, which provides a valuable reference for researchers in the field of food safety detection, and is of great significance to promote the healthy development of the food industry.
