With growing importance of nutrition in healthcare, NMR
can be used to obtain metabolosensory signatures related
to food. In this context, organoleptic property of 23
nutraceuticals (13 sweet, 10 pungent) has been analysed
with proton NMR and correlated with objective taste
measurements using Electronic Tongue. Similar
classification was arrived at independently by PCA
analysis of data from NMR and Etongue. Potential
spectral markers such as sucrose (sweet) and non-sweet
amino acids like valine and isoleucine (pungent) could
provide NMR sensory descriptors. With increasing
interest in nutritional therapeutics, NMR based
chemosensory signatures could open new vistas of
application in nutritional healthcare.
