Abstract:

The quality of single component of the food allergen protein plays a key role in food allergies research.Recombinant proteins prepared by E. coli or yeast expression system have a number of advantages, such as high efficiency,high purity, good homogeneity and so on, which have been applied in the preparation of reference material, allergendetection, the production of hypoallergenic protein and laboratory research. Recombinant food allergens used as thesubstitutes for natural allergen extracts have shown great potential to provide a new way to produce standard allergenproteins with high quality.

Key words: food allergens, gene expression system, recombinant protein
