Nuclear magnetic resonance (NMR) spectroscopy is an investigation technique to study matter. It is based on the properties of magnetically active nuclei, which respond to a perturbation induced in a sample by applying a radio wave pulse. The nuclei, if immersed in an intense magnetic field, respond to the pulse by oscillating at a particular frequency, thus generating a signal which is recorded and transformed by the instrument as a graph, the so-called spectrum, reporting the intensity of the response as a function of the oscillation frequency. The frequency of each nucleus is characteristic of its position in the molecule and depends on the physico-chemical state of the substances. The response depends, in fact, not only on the structure of the molecule to which the atom belongs to, but also on the chemical environment in which the molecule is immersed.

i wanna have some information about application of NMR in food industry
