Based on detection of 16-O-methylcafestol, or 16-OMC, in coffee via benchtop NMR, this new analytical service reduces the analysis time from 3 days (current standard analytical technique) to 40 minutes and is not only a more rapid but also cost-effective alternative. With a detection limit of 2%w/w robusta in Arabica, it also has the required sensitivity to detect levels suggestive of substitution for economic gain.
Should it be required, a further test (by LC-MS at additional cost) is able to provide quantification of the levels of 16-OMC detected.
