Adulteration in honey
- The CSE has resorted to the Nuclear Magnetic Resonance (NMR) testing to 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.
- Current regulations specify around 18 parameters that honey must comply with for producers to label it ‘pure honey.
- Among the tests employed as per Indian regulations is one to check whether the honey is adulterated with C4 sugar (cane sugar) or C3 sugar (rice sugar).
- Most samples cleared these tests but failed another test called the Trace Marker for Rice test, to test for rice syrup adulteration.
Significance of the CSE study
- Adulteration of honey is a global problem with several countries, including India, devising regulations and new tests to check it.
- It also destroys the livelihoods of bee-keepers who found it unprofitable to make pure honey because sugar-syrup honey was often available at half the price.
- Some Indian companies in the honey business were importing synthetic sugar syrups from China to adulterate honey.
- This shows how the business of adulteration has evolved so that it can pass the stipulated tests in India.
Back2Basics: Nuclear Magnetic Resonance (NMR)
- NMR spectroscopy is a crucial analytical tool for organic chemists.
- It is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.
- It is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials.
- It is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI).
