The problem of the detection of ''hidden'' allergens in food is a majo
r concern for both the industry and consumers at present. The producti
on of specific antibodies against two such food components, peanut and
sesame, is described. Immunoassays are presently the method of choice
for detection and identification of a wide range of food components,
and ELISAs (enzyme-linked immunosorbent assays) for both peanut and se
same have been set up. Who might use such assays for maximum benefit,
and in what format they should be provided, are key questions for food
analysts, and the issues are discussed. (C) Munksgaard 1998.
