Rare earth elements distribution in grape berries

Abstract

Rare Earth Elements (REEs) include 15 lanthanides, yttrium and scandium. Their occurrence in soil and plants seems to be closely tied to the geological composition of the underlying mother rock, to the physical and chemical properties of the soil and to the specific ability of the plant to take up and accumulate these microelements. To date knowledge regarding the composition and distribution of trace elements in Vitis vinifera has been lacking or is inadequate. The aim of this research was to study REEs distribution in Chardonnay berries harvested at ripeness in 2006 in Trentino (north-eastern Italy).
After washing and microwave acid digestion, both the total REEs content in the berries and the REEs distribution within the skin, seeds and flesh were quantified. Analysis of 13 elements (yttrium, Y; lanthanum, La; cerium, Ce; praseodymium, Pr; neodymium, Nd; samarium, Sm; europium, Eu; gadolinium, Gd; dysprosium, Dy; holmium, Ho; erbium Er; thulium, Tm; ytterbium, Yb) was carried out with an inductively coupled plasma mass spectrometer.
The total REEs content measured in berries was 2.079 μg/kg of fresh weight. The order in terms of percentage content within the berry was skin > flesh > seeds (p<0.05) for Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Ho and Er. For Tm and Yb there were no significant differences between the skin and flesh. Eu showed a significantly different distribution pattern.

Effect of alcoholic strength on the phenolic and furfural compounds of Brandy de Jerez aged in Sherry Casks®

Brandy is a spirit drink produced from wine spirit aged for at least six months in oak casks with a capacity of less than 1000 L and minimum alcohol by volume (ABV) of 36%. During the aging process, physicochemical and sensory changes take place. Manifested by colour, flavour or aroma variations that improve the quality of the initial distillate.

Application of cyclic voltammetry to the classification of enological tannins in relationship to oxygen consumption rate and botanical origin 

Enological tannins are a diversified group of winemaking products that vary in several aspects such as chemical composition, botanical origin, and production method. In consideration of their richness in phenolic compounds, one of their main application in vinification is related to their antioxidant capacity, in particular their ability to consume oxygen during red wine maturation.

Kinetic study of browning caused by laccase activity using different substrates

To our knowledge all the studies about laccase kinetics and its inhibition have been performed with substrates and conditions very different from those of real grape juice. Moreover, none of these researches really measure enzymatic browning, since they have not taken into account what happens after the oxidation of o-diphenols in o-diquinones and their subsequent polymerization to form melanins1. For that reason, the aim of this research was to develop a new model to measure the kinetics of browning caused by Botrytis cinerea laccase under conditions much closer to those of grape juice and using the substrates naturally present in it.
