Untersuchungen über die Vorgänge beim Dämpfen von Kaffeebohnen

The reactions occurring during steam treatment of green coffee have been investigated. In the condensate as well as in the treated beans 3-methoxy-4-hydroxystyrene (3,4-MHS) could be detected. In the condensed steam also benzaldehyde, phenylacetaldehyde, isovaleric acid, furfural and coffeine were identified. The 3,4-MHS is formed from the feruloylquinic acid present in the raw coffee. A method for the quantitative determination of 3,4-MHS has been developed
