Pyruvic acid kit
Contact our expert for more informations.
Pyruvate is mainly found in wine as it is produced by the energy metabolism of yeast during glyceropyruvic fermentation where, from glucose, for every molecule of glycerine formed, a molecule of pyruvic acid accumulates. The concentration can vary from tens to hundreds of mg/l.
This acid, which is very reactive at a chemical and enzymatic level, is the precursor of several substances that can be at the origin of olfactory defects in wines: acetic, mouse taste, burnt.

ADVANTAGES
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.
KIT ENZIMATICI E COLORIMETRICI STEROGLASS
I kit enzimatici e colorimetrici sono ampiamente usati nel controllo qualità per le principali determinazioni analitiche dei più svariati prodotti alimentari quali: succhi di frutta, vino, birra, latticini, uova, carne e per il controllo dei processi di fermentativi svolti dai microrganismi per la determinazione degli zuccheri, degli acidi organici e di altri componenti quali solfiti, composti fenolici, metalli.
Basata su enzimi purificati di alta qualità, l'analisi enzimatica consente misurazioni precise, molto accurate e ripetibili, anche in matrici complesse. Infatti la variazione dell’assorbanza, misurata a livello spettrofotometrico a seguito delle trasformazioni enzimatiche, è strettamente correlata alla concentrazione dei vari analiti ricercati.
