Any label applied at the farm is likely removed during processing and packaging steps - and replaced by new labels. Chain of custody depends on human intervention.
Labels Cannot Definitively Prove Where Food Was Grown or Raised
Photosynthesis embeds a signature into the molecular structure of every plant. The signature depends on plant type and growing locations. Coffee grown in Costa Rica has a different signature than coffee grown in Brazil.
There’s a Better Way. Use Nature’s Barcode.
These signatures are passed along the food chain, from soil or rain, to plants to animals and on to humans. You can’t remove it, you can’t wash it off. Nature’s barcode. It’s everywhere.
Definitive Proof of Food Origin
Second level. Touch deeper shows how isotopes work.
Not All Alike: Carbon and Water Isotopes
CO2 and H2O molecules in the air are made up of isotopes – carbon-13 compared to carbon-12 or deuterium compared to hydrogen - which have different atomic weights.
Carbon & Water: The Ultimate Tracers
Plants uptake CO2 and H2O and convert to hydrocarbons which are consumed by animals. The isotopes from the air are processed differently creating specific isotopic signatures which depend on plant type and growing region
We combust a food product which re-releases the CO2 and H2O in the isotopic composition that the plant or animal processed when it was growing or feeding

We ‘Read’ the Released Gases Using Optical Spectroscopy
We measure ratio of carbon-13 compared to carbon-12 or deuterium compared to hydrogen in CO2 and H2O – and provide a simple reading that determines a region
