It’s not just the technology we can help you with. We have a team of world-class scientists and researchers – including our biotechnology specialists – who can offer advice and technical expertise to help you protect and prove the authenticity of your products.

Did you know?

  • Nuclear Magnetic Resonance (NMR) is rapidly being adopted as the definitive global standard for ‘chemically fingerprinting’ foods and beverages because it can be used to prove the authenticity and provenance of these products.

  • NMR spectroscopy can analyse substances, such as pharmaceutical products, to determine their chemical structures and confirm the identity and purity of compounds.

  • Callaghan Innovation’s NMR service processes 22,000 samples per year, operates 24/7 and offers a walk-up service during normal working hours to users trained to submit their own samples on the NMR spectrometers for routine analyses.

  • NMR does not require you to know the specific compound or compounds you are looking for and it can reveal multiple components in a sample using a single measurement.

  • Food fraud and the adulteration of food products present a major risk to New Zealand’s export earnings and its reputation as a supplier of premium products and its reputation as a supplier of premium products – we have already seen the fallout from the discovery of melamine in milk powder, the large fines levied against winemakers for exporting wine with sugar added, and international media reports that six times the volume of Mānuka honey actually exported from New Zealand is being sold worldwide.

  • NMR technology featured in the first episode of the Netflix docuseries Rotten.
