General description

p-Cresol is a simple monophenolic aroma compound that occurs naturally in buckwheat honey. It is one of the main volatile compounds responsible for the sheepy-muttony aroma in ovine fats. p-Cresol is also reported to be responsible for the undesirable cowy/barny flavor in nonfat dry milk (NDM).
