The
most abundant esters were methyl and ethyl esters of some
organic acids; they are probably produced through the
biosynthetic pathway in potherb mustard cell tissue during
growth and pickling fermentation. Some esters absent from
the fresh potherb mustard but present in the pickles, such
as 2-phenylethyl acetate, ethyl decanoate, ethyl phenylacetate
and ethyl 3-phenylpropionate may be produced during
fermentation.
