This Application Note describes both HPLC and UHPLC methods to simultaneously separate and identify seven tannin compounds as aging markers in barrel-aged alcoholic beverages. The proposed methodology was applied to four different matrixes: whisky, brandy, rum, and tequila, to demonstrate a correlation between aging time and total tannin concentration level. Such a methodology could easily lead...

Zhi-Zi-Da-Huang decoction (ZZDHD), a classic traditional Chinese medicine (TCM) formula, has been used for centuries to treat alcoholic liver disease. Reliable therapeutics of ZZDHD has also been validated in clinical practice. In this study, molecular docking and network analysis were carried out to explore the antioxidative mechanism of ZZDHD as an effective therapeutic approach to treat alco...

Many medicinal plants have been recommended for the treatment of snakebites. Aqueous and alcoholic extracts of dried seed powder of Tamarindus indica were tested for their antioxidant and inhibitory activity of toxic enzymes like PLA2 and proteinases of Naja naja venom. Compared with alcoholic extracts the methanolic extract, displayed a significant inhibitory effect on the tested enzyme activi...

Osmotic distillation technique was used for the total dealcoholization of a red wine (Aglianico grape variety) up to 0.19 vol.%. The dealcoholization process was performed in subsequent cycles which gave rise wine samples at different alcoholic degrees. The effect of processing on the main chemical and physical properties of Aglianico wine was evaluated. Among wine samples, no significant diffe...

Sugar cane spirits are some of the most popular alcoholic beverages consumed in Cape Verde. The sugar cane spirit industry in Cape Verde is based mainly on archaic practices that operate without supervision and without efficient control of the production process. The objective of this work was to evaluate samples of industrial and alembic sugar cane spirits from Cape Verde and Ceará, Brazil usi...

The physiological and industrial importance of cholic and desoxycholic acids, the two main constituents of the bile acids, makes very desirable a method for their qualitative separation and, if possible, for their quantitative determination. The difference in their solubilities in various solvents or of the solubilities of the salts used in their preparation (1) is not very marked and causes lo...

Boletus edulis is a wild edible mushroom habitually consumed by rural populations. Ethanolic and methanolic extracts was obtained in cold and hot water from dried fruit bodies. The antioxidant activity of freeze-dried extracts from B. edulis were investigated using free radicals scavenging activity, reducing power, metal chelating effect, inhibition of lipid peroxidation, and the identification...

Eight commercial beers (3 lager beers, 2 dark ales and 3 high-alcoholic ales) were aged for one year under normal storage conditions, and the changes with time of flavour profile and the concentration of 15 volatile compounds were monitored. The compounds were chosen as markers to evaluate the importance of different reactions in the aging process of each beer type. The development of typical a...

Wine is known as a source of bioactive compounds and one the alcoholic beverages with highest phenolic content. There has been growing interest in composition wine due to its beneficial properties for human health. This work focuses on biologically active sensory attributes white presents research chemical profiles relation their geographical origin, varieties storage. The aim this study was in...

New or used barrels can be applied in ageing of alcoholic beverages. Compounds adsorbed wood migrate between beverages along with extractives. As barrel is costly and time-consuming, processes using fragments have been gaining interest. These generate residues for which the reuse still not well established. This work aims at oak additive Oak chips, previously immersed fortified wine, were to be...
