IgE-mediated hypersensitivity to taugeh (sprouted small green beans).

This report describes a case of allergy toward taugeh (sprouted small green beans), an important constituent of eggroll. With use of the skin prick test, RAST, and histamine release test, IgE antibodies against taugeh extract could be demonstrated. A partial cross-reactivity was observed between IgE-binding components from taugeh and peanuts. Peanut allergic patients could also experience adverse reactions after ingestion of taugeh.
