“…For instance, coulometrically determined antioxidant capacity using electrogenerated bromine as a titrant allows for the classification of extra virgin olive oils [76]. TAC and FRP parameters can be used for the detection of crude forgery of brandy [79] containing the non-grape nature of spirits and "cocktail" of synthetic and other flavoring agents instead of lignin ethanolysis products (ellagic and gallic acids, syring-and coniferaldehydes, etc.). Moreover, FRP is a more selective parameter because a lesser number of compounds (mainly dihydroxybenzenes) react with the titrant.…”

The definition of antioxidants (AOs), their classification and properties as well as electrochemical sensor systems for AOs analysis are briefly discussed. The analytical capabilities of coulometric titration with electrogenerated titrants as sensor systems for AOs determination have been considered in detail. The attention focused on the individual AO quantification that was mainly used in the pharmaceutical analysis and estimation of total antioxidant parameters (total antioxidant capacity (TAC), ferric reducing power (FRP) and ceric reducing/antioxidant capacity (CRAC)) allowing the fast screening of the target samples including their quality control. The main advantages of coulometric sensor systems are pointed out. The selective quantification of individual AO in a complex matrix using a combination of chromatography with coulometric or coulometric array detection under potentiostatic mode is discussed. The future development of coulometric sensor systems for AOs analysis is focused on the application of novel coulometric titrants and the application of coulometric detection in flow injection analysis.

“…Cognac and brandy antioxidant capacity was investigated by chronoamperometry (Ziyatdinova, Salikhova & Budnikov, 2014a) and differential pulse voltammetry (Ziyatdinova, Salikhova & Budnikov, 2014b), using multi-walled carbon nanotube (MWNT) modified glassy carbon electrode in both cases. In addition, Ziyatdinova, Salikhova, Skorobogatova, Chibisova & Budnikov (2015) investigated the potential of coulometric titration, differential pulse voltammetry (DPV), and chronoamperometry for evaluation of brandy quality using antioxidant properties. Guiberteau-Cabanillas, Godoy-Cancho, Bernalte, Tena-Villares, GuiberteauCabanillas & Martínez-Cañas (2015) developed a method for the electrochemical characterization and determination of the total content of phenolic compounds with low oxidation potential in an industrial cork by-product (cork boiling water) by using graphene modified screen-printed electrodes.…”

Influence of extraction time, solvent and wood specie on experimentally aged spirits – A simple tool to differentiate wood species used in cooperage

Type of the wood used for the aging highly influences the quality of alcoholic beverages. In this research we explored the potential of cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to establish fingerprints characteristic for each wood and to enable determining the type of the wood used in the aging process. Eleven different wood samples were used to prepare three different types of spirits during 15 months. The highest extraction rate was obtained during the first month, while further aging was followed with almost constant amount of extracted polyphenols. Black locust, myrobalan plum, and mulberry extracts were discriminated from the spirits aged in oak and wild cherry wood when statistical analysis was applied. Although clear classification of all samples was not achieved, this long term study demonstrated a potential of both CV and DPV for differentiating wood species used in the aging, hence in the quality control of spirits.

“…Aged distilled beverages, namely cognac and brandy, contain natural phenolic antioxidants that are often considered as quality markers for these beverages [1]. Phenolic acid (gallic and ellagic) and aromatic aldehydes (vanillin and syringaldehyde) are the major contributors to the antioxidant properties of aged distilled beverages [1][2][3]. Their simultaneous determination is of practical interest.…”

Aged distilled beverages (cognac and brandy) contain phenolic antioxidants as their quality markers. Voltammetric sensors based on the carbon nanotubes and electropolymerized pyrocatechol violet (PCV) or p-aminobenzoic acid (ABA) were developed for the simultaneous determination of the phenolic antioxidants in cognac and brandy. The polymerization conditions of PCV and ABA were optimized. Sensors allow for the simultaneous sensitive determination of gallic and ellagic acids as well as syringaldehyde and vanillin. The analytical characteristics are improved vs. other modified electrodes. The sensors show selectivity in the presence of typical interferences and other natural phenolics. The sensors that were developed were tested on cognac and brandy samples.
