| titleOfInvention | A kind of discrimination method being used for chaste honey, rape honey and acacia honey based on nuclear magnetic resonance technique |
| abstract | The invention discloses a kind of discrimination methods based on nuclear magnetic resonance technique for chaste honey, rape honey and acacia honey, and honey sample is configured to the solution of 0.03-0.5g/L with heavy water after filtering；The phosphate buffer solution that concentration is 0.5-2.0 mol/L is added, wherein, sodium azide containing 3- trimethylsilyl -1- propyl sulfonic acid sodium inner mark solution and 0.1-3.0 mM that volume fraction is 0.05-0.3% in phosphate buffer solution, mixing, adjustment pH is 2.5-4.0, measures to obtain nuclear magnetic resoance spectrum through nuclear magnetic resonance spectrometer；The chemical shift of honey sample marker is analyzed, 1 The deviation △ δ that H chemical shift δ is 7.0ppm~7.5ppm is chaste honey within 0.02-0.05ppm range, is otherwise rape honey or acacia honey.This method can analyze a large amount of samples in the short time, quickly identify point chaste honey and rape honey and acacia honey. |
