Verifying and guaranteeing the highest food quality for the consumer is nowadays possible using isotopic methodologies. Bomb Carbon is the method of choice to assess the production year for wine and oil and several other foodstuffs, while stable isotopes find widespread applications in food traceability to evaluate the quality, authenticity and origin of labelled products (Isotope Ratio Mass Spectrometry) or to determine the provenance of animal and vegetal foods (Inductively Coupled Plasma Mass Spectrometry).

Stable isotopes can be utilised to study water addition to wines or to evaluate wine adulteration by the addition of exogenous sugar. Isotopic analyses of foods have become a widespread tool to evaluate the quality, authenticity and origin of labelled products, like wines, alcoholic beverages and fermented fruit juices, mozzarella cheese.
In details radiogenic ⁸⁷Sr is the long-lived radiogenic daughter of ⁸⁷Rb and can be utilized to determine the provenance of animal and vegetal foods (like wine and oil). Different geographical zones are characterized by a given ⁸⁷Sr fingerprint to produce isoscapes. The ⁸⁷Sr/⁸⁶Sr ratio is not modified during the uptake of the plant and it is transferred unaltered to all living beings of the food chain, thus remaining identical to that of the substratum from which the original plant or vegetable grew.
Radiocarbon analyses also allow to determine the bio-based material percentage in agri-food products, as well as in bio-fuels.
