[0030] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0031] 1. Obtaining high-purity milk allergens
[0032] β-lactoglobulin, α-lactalbumin, and casein in milk are the main allergens that cause allergic reactions. At present, these components are commercially available with high-purity labels, which can be obtained by order, or according to The purification method reported in the literature is obtained by self-extraction. Our laboratory has explored a mature purification process for extracting high-purity single allergens such as β-lactoglobulin, α-lactalbumin, and casein. Now take β-lactoglobulin as an example to introduce the extraction process.
