A rapid, simple, reliable and accurate method for the specificmeasurement of tartaric acid in wine, fruit juice and other materials.This kit includes a homogenous assay for red wine that is amenable toautomation. Supplied as a “ready to use” liquid stable formulation thatis suitable for manual, autoanalyser and microplate formats. INTRODUCTION: Tartaric acid occurs naturally in grapes and is one of the most prevalent organic acids, along with L-malic acid, present in wines. Throughout the wine making industry it is assumed that tartaric acid is the only acid that contributes to total (titratable) acidity in wine and as such the measurement of tartaric acid is used as the key indicator of total acidity. The general levels of total acidity in wines range from approximately 0.4 to 1.0% (w/v). During the wine making process, if the total acidity of a wine is too low, tartaric acid can be added to the wine to increase the level of acidity and consequently decrease the pH level. This in turn acts as a preservative against microbial spoilage. This kit (K-TART) is suitable for the specific measurement of tartaric acid, especially in wines and fruit juices. KITS: Kits suitable for performing 200 assays in manual format (or 2000 assays in auto-analyser format or 2000 assays in microplate format) are available from Megazyme. The kits contain the full assay method plus: Bottle 1: Clarifying Agent (11 mL) Stable for > 2 years at room temperature. Bottle 2: (2x) Tartaric Acid Reagent 1 (44 mL) Stable for > 1 year at 4°C.
