A synthetic food dye used in processed foods like confections, soft drinks, flavoring syrups, condiments and convenience foods in order to create a potent yellow or bright green coloring. Prevalence of allergenicity is unclear but it is the most likely azo dye to cause hypersensitivity and reactions may occur from ingestion or skin contact.
An allergen is an otherwise harmless substance that triggers an allergic reaction in sensitive individuals by stimulating an immune response.. In technical terms, an allergen is an antigen that is capable of stimulating a type-I hypersensitivity reaction in atopic individuals through immunoglobulin E (IgE) responses. [1]
[2] [3] The first steps in making an edible vaccine is the identification, isolation, and characterization of a pathogenic antigen. [1] In order to be effective, the antigen needs to elicit a strong and specific immune response. Once the antigen is identified and isolated, the gene is cloned into a transfer vector.
An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]

In contrast, the B cell antigen-specific receptor is an antibody molecule on the B cell surface and recognizes native (unprocessed) antigen without any need for antigen processing. Such antigens may be large molecules found on the surfaces of pathogens, but can also be small haptens (such as penicillin) attached to carrier molecule. [60]
Certain foods have also been shown to help clear congestion, says Dr. Mercola. “Raw garlic, when chopped or crushed to release its beneficial compounds, can help fight infection.” Horseradish ...
The antigens may be for example glycoproteins on the cell membrane of erythrocytes that are key molecules that determine blood types. Depending on the chemical nature of the antigens, blood types have different levels of hypersensitivity; for instance, A and B are more antigenic than other antigens. [10] Type II hypersensitivity
