| titleOfInvention | A kind of method improving flammulina velutipes anti-oxidant activity |
| abstract | The present invention discloses a kind of preparation method improving flammulina velutipes anti-oxidant activity.The present invention adopts controlled enzymatic hydrolysis method to regulate and control the molecular weight distribution of flammulina velutipes, after needle mushroom is pulverized, by removal of impurities, hot water extraction, removing protein, concentrated is separated acquisition flammulina velutipes with ethanol precipitation, then carries out control degradation with enzyme process and drop to 19000-30000Da to make the molecular weight of flammulina velutipes.Adopt the flammulina velutipes prepared by this method, be suitable for suitability for industrialized production, gained polysaccharide extract rate improves 2.5-3.5 doubly than traditional water extraction, and has obvious anti-oxidant activity.In DPPH free radical system, the IC50 of flammulina velutipes is 1.69-2.12mg/mL, and ORAC value is up to 923 μm of olTrolox/g simultaneously. |
