Enzymes Effect of Dried Tangerine or Orange Peel Tea by Ultraviolet Spectrophotometry |
| |
| Abstract: | Objective] The aim was to determine enzymes effect of dried tangerine or orange peel tea by ultraviolet spectrophotometry. Method] Full wavelength scanning was used to determine the absorption peak of the dried tangerine or orange peel tea drinks, and then the sample OD value was determined by UV spectrophotometry, and figured out T value.Result]The relative standard deviation of the stability of the method was 0.086%;the RSD relative standard deviation of the stability of the method was 0.210%, and the sensitivity was higher than sensory evaluation at least 125 times. Conclusion] Effect of enzyme solution is studied with UV spectrophotometry , and the method has good precision, high sensitivity and good stability. |
