Malic Acid | Test kit for Autoanalyser

Analytical principle

The Vintessential™ Malic Acid test kit provides automated determination of malic acid concentrations in wine, juice and must samples. The assay is commonly used throughout the winemaking process to monitor acid composition, assess grape maturity and track fermentation progress.

Malic acid is quantified using a series of enzyme-catalysed reactions that generate a measurable change in absorbance. The analyser automatically measures this change, allowing accurate determination of malic acid concentrations across a wide range of sample types.

The method delivers reliable, repeatable results while supporting efficient laboratory workflows and high sample throughput.
