'Caramel receptor' identified

Who doesn't like the smell of caramel? However, the olfactory receptor that contributes decisively to this sensory impression was unknown until now. Researchers at the Leibniz Institute for Food Systems Biology at the Technical University of Munich (LSB) have now solved the mystery of its existence and identified the "caramel receptor". The new knowledge contributes to a better understanding of the molecular coding of food flavors.
