NUCLEAR MAGNETIC RESONANCE TEST
No Comments
Subject: Science & tech
Context: Honey marketed by prominent Indian brands failed a key test of purity, the Centre for Science and Environment (CSE) has claimed, citing an investigation it conducted.
Concept:
- Current regulations specify around 18 parameters that honey must comply with for producers to label it ‘pure honey’.
- Most brands passed muster but when subjected to one test, called Nuclear Magnetic Resonance (NMR) that was done at a lab in Germany, only three brands passed: Saffola, MarkfedSohna and Nature’s Nectar. There were often multiple samples tested for each brand.
Additional Information
- Nuclear Magnetic Resonance (NMR) Test can ascertain the composition of a product at the molecular level)
- The NMR test is not required by Indian law for honey that is being marketed locally but is needed for export.
