COMPARISION BETWEEN BERTRAND METHOD AND COMPLEX TITRATION, APPLYING TO DETERMINE SUGAR CONTENT IN FRUIT

Abstract

In this study, a method of complex titration to determine sugar content in a variety of fruits was established and the results are compared with Bertrand method. A range of parameters including extracting solvent, time of extraction, repeatability and accuracy of the method were investigated. The fruit samples were sent to Quality Assurance and Testing Center 3 (QUATEST 3) for testing and it is proved a high correlation between these tests. This method was also providing more superior features including short analytical time, higher accuracy in comparison with Bertrand method
