Abstract
A new and simple procedure has been developed for the determination of fructose, in which only a sodium metaborate solution is used for titrating the fructose solution. Sodium metaborate forms boric acid and sodium hydroxide by hydrolysis. The boric acid reacts with fructose to form a fructose-boric acid complex, which is then neutralized with sodium hydroxide. Namely, the boric acid used to form the complex and the sodium hydroxide used to neutralize it are generated in the same quantity and simultaneously by the addition of sodium metaborate. The present method was compared with the Somogyi′s method. The F test revealed no significant differences between the two methods at the 95% significance level.
