Allergen standard is a kind of reference material with high purity, which is widely used in allergen analysis. In addition, allergen standard is also a kind of physical standard, which has many species. However, it also has certain index requirements for allergen standards, including specific physicochemical properties and immunological properties.
The physicochemical properties mainly include composition identification, purity, uniformity, secondary structure and others. Therefore, appropriate procedures and processes should be chosen to prevent contamination when preparing allergen standards. Common allergen standard substances mainly include ovotransferrin, ovomucoid, α-lactoalbumin, β-lactoglobulin and others.
Food allergen analysis field: Allergen standards are widely used in food allergen analysis field, which can be divided into standard substances containing matrix and pure standard substances without matrix. Allergen standards are applied in the food allergen analysis field mainly to prevent consumers from eating allergenic food by mistake and endangering life and health. Allergen standards can be isolated and purified from egg, milk and peanut, which are three kinds of highly allergenic foods. The allergen standards isolated and purified from eggs mainly include ovotransferrin, ovomucoid, ovalbumin and lysozyme. The allergen standards isolated and purified from milk are α-lactoalbumin, β-lactoglobulin and casein. Arah 1 to Arah 11 are eleven allergen standards extracted from peanut.
Textile allergen analysis field: Allergen standards have important applications in textile allergen analysis field. Ingredients such as raw materials and additives used in the textile preparation process may become sensitizers, such as sensitizing dyes and sensitizing auxiliaries. In addition, some substances with low boiling points may be released during the wearing process, causing human allergies. All of these substances can be analyzed quickly and accurately using allergen standards to protect the personal safety of consumers.
Others: In addition to the applications in the above fields, allergen standards have been widely used in the fields of household appliances, furniture, indoor air detection and many other fields.
