ISO 750:1998

Overview

ISO 750:1998 - Fruit and vegetable products - Determination of titratable acidity is an international standard developed by ISO Technical Committee 34/SC 3. This standard outlines two recognized laboratory methods for the precise determination of titratable acidity in fruit and vegetable products: the potentiometric reference method and a routine method using a colored indicator. Effective assessment of titratable acidity is critical in quality control, research, and safety evaluation within the agricultural and food products industries.

Titratable acidity is a key parameter influencing the flavor, preservation, and processing behavior of fruits and vegetables. ISO 750:1998 provides globally harmonized methods to ensure the reliability and repeatability of results, supporting consistent product quality across international supply chains.
