Acid Value Measurement of Orange Juice by Automatic Titration
Application Overview
This application note describes the determination of acid value in orange juice using automatic potentiometric titration. Acid value is a key quality control parameter used to assess product consistency, flavor balance, and conformity with production specifications in fruit juice manufacturing.
Analytical Method
The method employs neutralization titration with standardized sodium hydroxide solution to a defined pH endpoint (pH 8.1). Automatic titration enables precise endpoint detection, consistent results, and reduced operator variability compared to manual titration techniques.
Sample Type
