Study of mineral profile of Montilla-Moriles “fino” wines using inductively coupled plasma atomic emission spectrometry methods

Determination of Metals and Metalloids in Wine Using Inductively Coupled Plasma Optical Emission Spectrometry and Mini-torch

“…For the determination of elemental composition of wines, it is required to properly prepare the samples. Taking into consideration that wine is a complex water-ethanol mixture, containing various inorganic and organic substances at different levels (Álvarez et al 2007;Pyrzyńska 2007;Gonzálvez et al 2008;Moreno et al 2008;Voica et al 2009;Rodrigues et al 2011), the sample preparation stage is very important in the analysis of particular wine components. The preparation of wine samples for metal and metalloid determination includes microwave-assisted acid digestion, UV-assisted digestion, thermal digestion in an open reactor, sample dilution, dry Electronic supplementary material The online version of this article (doi:10.1007/s12161-016-0567-6) contains supplementary material, which is available to authorized users.…”

Optimization and Validation of a Microwave Digestion Method for Multi-element Characterization of Vranec Wines

“…Elements Al, Cd, Cu, Fe, Ni, Pb, and Zn could be determined without dilution, while elements Ca, K, Mg, and Na are analyzed after dilution of wine sample with water (Frias et al 2001;Frias et al 2003;Diaz et al 2003). Decomposition could be performed by wet digestion on a hot plate or in a microwave oven using concentrated HNO 3 , HClO 4 , and H 2 SO 4 or mixtures of these acids (Frias et al 2001;Frias et al 2003;Diaz et al 2003;Castiñeira Gómez et al 2004;Álvarez et al 2007;Ivanova-Petropulos et al 2013, 2015b.…”

Arsenic and other trace elements in wines of eastern Croatia

“…The quality of wine and its organoleptic features are directly related to its composition, which depends on various factors such as specific characteristics of production area: grape variety, type of soil, climatic conditions (generally referred to as 'terroir'), yeast culture and vinification practices, wine supply chain service including appropriate storage conditions (Álvarez, Moreno, Jus, Cameán, & González, 2007;Lara, Cerutti, Salonia, Olsina, & Martínez, 2005). Demands for high quality wines are increasing worldwide, as well as the need for better understanding the origin and characteristics of wine.…”

“…During the growth of grapes in a vineyard, contaminations can be classified as geogenic (originating in the soil), originating from fertilising and plant protection practices, or from environmental pollution (Pohl, 2007). Application of pesticides, fungicides and fertilizers containing As, Cd, Cu, Mn, Pb and Zn compounds leads to an increase in the amounts of these elements in soil, grape and wine (Álvarez et al, 2007;Cvetković , Arpadjan, Karadjova, & Stafilov, 2006;Galani-Nikolakaki, Nallithrakas-Kontos, & Katsanos, 2002;Kment et al, 2005;Kunkee et al, 2003;Lara et al, 2005;Pohl, 2007). Finally, there is an enological (winemaking) source of metals, as contamination may occur at different steps of wine production.…”
