This standard specifies two methods for determining the titratable acidity of fruit and vegetable products, namely potentiometric titration and indicator titration. This standard is applicable to the determination of titratable acidity of fruit and vegetable products and fresh fruits and vegetables. Potentiometric titration is an arbitration method. Indicator titration is a routine method. Indicator titration is not suitable for samples with darker leaching solution.
