The flavour thresholds of the 239 compounds examined varied over a range of 2 x 10¹², and on occasion, compounds of high chemical purity (99% +) were organoleptically impure or even misflavoured.1976, Food Science and Technology Abstracts, page 9:
This means that impurities present at the ppu level can easily misflavour the compound under study.1981, Morten Christian Meilgaard, Beer Flavour, page 24:

'Chemically pure' compounds may be strongly misflavoured by contaminants, and in some cases the threshold measured may inadvertently be that of an impurity.1986, Ian Douglas Morton, Alexander Joseph MacLeod, Food Flavours - Part 2, page 112:
misflavour
noun
Etymology From mis- + flavour.

The state of being misflavoured.
Powders produced in those days were, compared with today's standards, of poor flowability and solubility, difficult to handle, dusty, and prone to misflavour as a result of degradation in the drying process.1997, Christopher G.J. Baker, Industrial Drying of Foods, page 90:
Durhang had a way of making one ravenous, sufficient to overcome the dreadful misflavours of such malodorous staples.2010, Steven Erikson, The Tales Of Bauchelain and Korbal Broach, Vol 1, page 102:
