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.

Optimizing the use of bentonite for better control of haze formation In white and rosé wines

In winemaking, the appearance of turbidity in white and wine is a serious visual defect, which lowers significantly its commercial value. A major cause of the formation of turbidity in wine is attributed to the presence of temperature-sensitive proteins.

Role of Grape-Extractable Polyphenols in the Generation of Strecker Aldehydes and in the Instability of Polyfunctional Mercaptans during Wine Oxidation

Wine longevity is a complex multifactor phenomenon in which the weight of the different factors is not well known. One of the key factors of wine longevity is related to its resistance to oxidation. This property can be defined as the ability of the wine, under an exposure to oxygen, to keep its color, avoid accumulation of acetaldehyde and Strecker aldehydes (SA), and keep as long as

MicrobiomeSupport: Towards coordinated microbiome R&I activities in the food system to support (EU and) international bioeconomy goals

Microbiomes have crucial roles in maintaining life on Earth, and their functions drive human, animal, plant and environmental health. The microbiome research landscape is developing rapidly and is performed in many different science fields using similar concepts but mostly one (eco)system at-a-time. Thus, we are only starting to unravel and understand the interconnectedness of microbiomes across the (eco)systems.

Application of satellite-derived vegetation indices for frost damage detection in grapevines

Wine grape production is increasingly vulnerable to freeze damage due to warming climates, milder winters, and unpredictable late spring frosts. Traditional methods for assessing frost damage in grapevines which combine fieldwork and meteorological data, are expensive, time-consuming, and labor-intensive. Remote sensing could offer a rapid, inexpensive way to detect frost damage at a regional scale. Remote sensing approaches were used to assess freeze damage in grapevines by evaluating satellite-derived vegetation indices (VIs) to understand the severity and spatial distribution of damage in several New York vineyards immediately after a frost event (May 17th-18th, 2023). PlanetScope 3m satellite images acquired before and after the freeze were used to map damage and measure changes in VIs for vineyards in the Finger Lakes region.
