ANTHOCYAN KIT
Contact our expert for more informations.
Anthocyanidins represent the red pigments of the plant kingdom; they accumulate in the epidermis of the grape exocarp and are found in the wine, after maceration, in varying concentrations of up to 600-800 mg/l in wines obtained from anthocyanin-rich varieties. Their determination is functional for the chromatic characterisation of wines, but also in terms of taste as they intervene in polymerisation phenomena with tannins causing a decrease in astringency. They also tend to react with SO2 (decolourisation) and are influenced by temperature, pH and oxidative conditions during ageing.
Anthocyanins show a maximum absorbance at 520 nm, and in the absence of a reference standard, the calculation factor used in the method is derived from experimental correlation tests with HPLC analytical methods.
Technical features
READY TO USE: Liquid and easy to use.
PRECISION AND SPECIFICITY: Characterized by high specificity, they provide accurate and repeatable data.
LOW COSTS AND LONG SHELF LIFE: Minimal cost per test and a long shelf life (average 24 months).
FAST ANALYSIS: Allow for quick and reliable results (up to 300 tests/hour), especially when used with automated instruments like our HYPERLAB series analyzers.
SIMPLE AND ECONOMIC CALIBRATION: It is possible to use single-method and/or multi-parametric calibration/verification standards. The determination of the Blank is performed automatically every 12 hours with the Hyperlab analyzers.
METHODS APPROVED BY INTERNATIONAL STANDARDS: Numerous enzymatic methods have been approved and validated by international organizations such as:
ISO (International Standardization Organization)
AOAC (American Association of Analytical Chemists)
IFU (International Federation of Fruit Juice Producers)
OIV (International Wine Office)
IDF (International Dairy Federation)
EBC (European Brewery Convention) and many others.
STERGLASS ENZYMATIC AND COLORIMETRIC KITS
Enzymatic and colorimetric kits are widely used in quality control for the main analytical determinations of a variety of food products such as fruit juices, wine, beer, dairy products, eggs, meat, and for the monitoring of fermentation processes carried out by microorganisms for the determination of sugars, organic acids, and other components such as sulfites, phenolic compounds, and metals.
Based on high-quality purified enzymes, enzymatic analysis allows for precise, highly accurate, and repeatable measurements, even in complex matrices. The absorbance variation, measured spectrophotometrically as a result of enzymatic transformations, is closely correlated with the concentration of the various analytes sought.
