| |
| Abstract: | A study on determination of total vitamin C in foods by fluorometric method is presented.A lot data showed that this method has many advantages such a shigh sensibility, good reproducibilty, good linear relationship and simple in procedure.This method had been used to determine the total vitamin C of some foods.It is found that the cofficient of variance is less than 3%, recovery is over 90% and the florosecence intensity is directly proportional to tolal vitamin C content while in low concentration. This method can be widely used for the determinatiom of total vitamin C in various foods. |
