| titleOfInvention | Fructosevaline preparation method |
| abstract | The invention discloses a fructosevaline preparation method which comprises the following steps: by taking 1-10 parts of L-valine and 10-50 parts of D-glucose as raw materials and 80-800 parts of 0.01-3 mol/L pyridinium acetate solution or pyridinium formate solution having a pH value of 3-6 as solvent, reacting while stirring at 10-50 DEG C for 1-5 days; after the reaction is finished, filtering, and drying the obtained solution by distillation under reduced pressure to obtain a dry matter; and dissolving the obtained dry matter in methanol or ethyl ether, standing at a low temperature of 0-10 DEG C to precipitate a light yellow matter, filtering, and performing freeze-drying to obtain a white solid matter, namely fructosevaline. The invention has the advantages of simple preparation steps, high yield and high purify of the prepared substrate. |
