Arsenic in soil, leaves, grapes and wines

Abstract

The presence of arsenic in food and beverages creates concern because of the toxicity of this element, classified as carcinogenic in humans. The arsenic concentration in soil, vine leaves and berries (cv. Chardonnay) and white wines was studied, considering vineyards near to an old mining area (naturally rich in As), in comparison with others from uncontaminated areas in Trentino (Italy).
All analyses were performed using an inductively coupled plasma mass-spectrometer.
In soil, the acqua regia extracted As ranged from 3.7 to 283 mg/kg, whereas bioavailable As varied from 18 to 639 mg/kg. As in washed and acid mineralised leaves and berries was between 16.3-579 mg/kg dw and between <0.1-36.8 mg/kg dw, respectively. As content in wines was always <1.4 mg/L. Pearson’s test showed significant and positive correlations between the As concentrations in soils, leaves and berries. The samples collected near the mining area showed significantly higher As concentrations.

S. CEREVISIAE AND O. ŒNI BIOFILMS FOR CONTINUOUS ALCOHOLIC AND MALOLACTIC FERMENTATIONS IN WINEMAKING

Biofilms are sessile microbial communities whose lifestyle confers specific properties. They can be defined as a structured community of bacterial cells enclosed in a self-produced polymeric matrix and adherent to a surface and considered as a method of immobilisation. Immobilised microorganisms offer many advantages for industrial processes in the production of alcoholic beverages and specially increasing cell densities for a better management of fermentation rates.

Evaluation de différents clones du Chardonnay pendant la maturation dans un terroir viticole du Friuli-Venezia Glulia (Nord-Est de l’Italie)

La diffusion récente et “explosive” du Chardonnay dans pratiquement toutes les zones de culture viticole du monde a fait penser, à tort, que cette variété s’adapte facilement à toutes les conditions pédo-climatiques ou presque. Cette thèse a été confirmée par la grande faculté d’adaptation dont a fait preuve le vignoble et par la popularité dont jouit le vin auprès des consommateur du monde entier.

Unveiling the unknow aroma potential of Port wine fortification spirit taking advantage of the comprehensive two-dimensional gas chromatography

Port wine is a fortified wine exclusively produced in the Douro Appellation (Portugal) under very specific conditions resulting from natural and human factors. Its intrinsic aroma characteristics are modulated upon a network of factors, such as the terroir, varieties and winemaking procedures that include a wide set of steps, namely the fortification with grape spirit (ca. 77% v/v ethanol).
