Arsenic in berries and its correlation with natural soil content: experience in Trentino (Italy)

Abstract

[English version below]

Il lavoro presenta l’evoluzione dei contenuti di arsenico nelle uve durante lo sviluppo e la maturazione, e la sua distribuzione nell’acino; verifica inoltre la relazione tra i contenuti di As nelle uve, nelle foglie e nei suoli caratterizzati da una dotazione differente e naturale di questo elemento.
Nella bacca l’arsenico cresce durante la stagione vegetativa e a maturazione è localizzato nella polpa (50%), nella buccia (40%) e in minima parte nei semi.
La correlazione tra i contenuti di As nelle bacche raccolte in 18 vigneti, nelle corrispondenti foglie e nei rispettivi suoli estratti con acetato di ammonio risulta statisticamente significativa.

The work illustrates arsenic content in grapes during development and ripening and its distribution in the berry, together with the relationship between As content in grape berries, leaves and soils where this element is naturally present in different amounts.
Arsenic increases in the berry during the growing season and is located in the pulp (50%), the skin (40%) and to a lesser extent in the seeds in ripe berries.
The correlation between the As content in berries collected in 18 vineyards and in the corresponding leaves and soils, extracted using ammonium acetate, is statistically significant.

Ripening of cv. Cabernet Sauvignon grapes: polysaccharides fractions evolution and phenolic extractability

Polysaccharides and more specifically pectins, make up a significant portion of the cell wall material of the plant cells including the grapes. During the fruit ripening the associated softening is related to the breakdown of the cell wall polysaccharides. During this process, it is expected that polysaccharides that are soluble in red wine will be formed influencing its texture. Anthocyanins are responsible for the wine color and tannins for the astringency, body and bitterness of the wine. In the skins, these compounds are located in the cell vacuoles and the barrier that conditions their extractability is the skin cell wall that may determine the mechanical resistance, the texture and the ease of processing berries. The aim of this work was study the evolution of the polysaccharides and the anthocyanin and tannin extractability during the ripening period in Cabernet Sauvignon grapes, trying to correlate these variables.

Applications of FTIR microspectroscopy in oenology: shedding light on Saccharomyces cerevisiae cell wall composition and autolytic capacity

Many microbial starters for the alcoholic and malolactic fermentation processes are commercially available, indicated for diverse wine styles and quality goals. The screening protocols cover a wide range of oenologically relevant features, although some characteristics could also be studied using underexplored powerful techniques. In this study, we applied Fourier Transform Infrared (FTIR) microspectroscopy [1,2] to compare the cell wall biochemical composition and monitor the autolytic process in several wine strains of Saccharomyces cerevisiae.
