As a naturally occurring reaction during food processing, glycation, also known as non-enzymatic browning or Maillard reaction, can improve food protein physiochemical properties and functionality. In this perspective, three aspects of glycation (terminology confusion between glycation and glycosylation, its current application, and its impact on immunoreactivity) are elaborated. Overall, the immunoreactivity of glycated proteins may decrease, remain unchanged, or even increase after food glycation. Also, it should be noted that the effect of glycation on the immunoglobulin (Ig)E- or IgG-binding capacity of allergens does not necessarily and correctly predict the allergenicity of the glycated protein in the allergic patient population.
