Abstract
A sample for NMR measurement of moisture and fat and oil contents is disclosed. The sample includes an organic portion containing at least some fats and oils, a pad that is substantially transparent to microwave radiation and is free of atoms that would interfere with or mask the NMR response of the protons in the fats and oils in the sample, and a sheet material that is free of atoms that would interfere with or mask the NMR response of the protons in the fats and oils in the sample, with the sheet material being wrapped around the organic portion and the pad.
Claims1
A sample for NMR measurement comprising:
- a food product comprising an organic portion containing at least some fats and oils on a pad comprising quartz fibers or glass fibers that is hydrophilic and lipophilic and substantially transparent to microwave radiation and is free of atoms that would interfere with or mask the proton NMR response of the protons in the fats and oils in the sample;
- and
- a sheet material comprising a polytetrafluoroethylene (PTFE) polymer that is free of atoms that would interfere with or mask the NMR response of the protons in the fats and oils in the sample, said sheet material being wrapped around said food product comprising said organic portion and said pad.
