International Conference on
Mass spectrometry for authentication of food products

ass spectrometry is an important analytical tool to
authenticate the geographical origin of various food
products. This is particularly important in the present world-
scenario of free trade agreement, terrorism, and to identify
the fraudulent approaches for money profits. A number of
mass spectrometric techniques, e.g. thermal ionization mass
spectrometry (TIMS), inductively coupled plasma source
mass spectrometry (ICPMS), stable isotope ratio mass
spectrometry (SIRMS), etc. are being increasingly employed
to fulfill the objective of geographical authentication. The
precise and accurate data on the isotopic composition of
some of the elements viz., B, Sr, Pb, C, O, etc.; concentrations
of trace elements in the food product and the soil; and the
chemometric analysis (e.g. principal component analysis PCA)
of the data provide valuable tools. Though fully automated
mass spectrometers are commercially available these days,
yet the high precision and accuracy required for the isotope
ratios demands a skilled analytical scientist with critical
evaluation of the various parameters affecting the precision
and accuracy of the analytical data. Examples will be shown
of various parameters which need be carefully examined to
get meaningful data. A number of studies are reported in
literature on different food products. This presentation will
summarize the internationally reported results on a few
food products (rice, coffee, tea. etc.) and discuss the results
obtained on tea leaves and rice grown within India. The talk
will also highlight the future requirements to satisfy the
various objectives of food authentication.
