Amidži Klari D., Klari I., Veli D., Vedrina Dragojevi I. (2011): Evaluation of mineral and heavy metal contents in Croatian blackberry wines. Czech J. Food Sci., 29: 260-267.The mineral and heavy metal contents in 17 commercially available Croatian blackberry wines were determined by FAAS/FAES and GFAAS. The concentrations of potassium, sodium, calcium, magnesium, iron, copper, manganese, zinc, cobalt, chromium, and cadmium were between (in mg/l) 924-1507, 11.81-120.10, 86.4-457.1, 183.4-381.2, 0.082-6.273, 0.058-0.767, 1.47-11.53, 0.247-6.645, and (in μg/l) 3.21-11.89, 10.08-15.88, and 0.55-9.9, respectively. A negative correlation was found between the concentrations of macro (Mg) and micro (Fe) minerals. Furthermore, positive correlations were observed between the concentrations of manganese, cadmium, and cobalt that indicated the origin of these elements in the anthropogenic source. Multivariate analyses (PCA/LDA) showed that the distinct patterns of the metal contents in blackberry wines could be identified with quite satisfactory accuracy (sensitivity and specificity) with the subregion of the origin. In regard to the results obtained, Croatian blackberry wines could be considered as safe from the health risk point of view and as a good additional source of the essential nutrients investigated such as manganese, magnesium, and potassium.Keywords: blackberry wine; minerals; heavy metal; multivariate analyses; PCA; LDA Blackberry (Rubus fruticosus, Rosaceae) is grown in continental Croatia on small farms using traditional techniques of cultivation and harvesting by hand in summers (July-August). Th ornless Logan, Th ornfree, Black Satin, and Tayberry are the most common blackberry cultivars in Croatia. A signifi cant proportion of fresh fruits is directly processed into blackberry products -jam, juice, or wine. Blackberry wine is a product of yeast fermentation of natural sugars present in blackberry juice. Th is popular fruit wine is mainly produced in the continental part of the country, which is divided into a number of subregions: from the Danube Basin, through Slavonia, Moslavina, Pokuplje, Plešivica, to Prigorje-Bilogora and Zagorje-Međimurje (Figure 1). Slavonia is a geographical and fertile agricultural area in eastern Croatia and the plantations in this subregion are located on the slopes of the central Slavonian mountain range. Prigorje-Bilogora subregion off ers favourable conditions for the cultivation of all kinds of fruits and vegetables, and the plantations are located on attractive hills. Zagorje and Međimurje are situated in the north-western part of the country. Th is subregion features a wide range of diff erent landscapes and types of vegetation.The quality of wine depends on numerous factors related to the specific production area, such as the plant variety, soil and climate, culture, yeast,

“…These wines had higher contents of magnesium than wines from other countries (Marengo & Aceto 2003;Moreno et al 2007;Pohl 2007) but lower than the highest value of 718 mg/l reported for Australian white wines, which had the widest range of magnesium (78-718 mg/l) (Sauvage et al 2002).…”

“…It is therefore not surprising that Vis-NIR spectroscopy is an extensively employed analytical method in the agricultural, pharmaceutical, chemical, petrochemical and medical fields (Osborne and Fearn, 1986;Osborne et al, 1993;Ciurczak and Drennen, 2002;Raghavachari, 2001;Sakudo et al, 2005;Sakudo et al, 2006a) The present study investigated the vibration mode of native states of metals in tissues using Vis-NIR spectroscopy. Hitherto, Vis-NIR spectroscopy has been routinely employed for vibration mode of metals in wines (Sauvage et al, 2002), legumes (Cozzolino and Moron, 2004), forages (Clark et al, 1987(Clark et al, , 1989, soils (Moron and Cozzolino, 2003), sediments (Malley, 1998;Malley and Williams, 1997), grasses and hays (Saiga et al, 1989;Smith et al, 1991), where metals are incorporated in complex organic matrices. Although detectable, metals per se exhibit no absorption in the NIR and red regions, since they form complexes with organic molecules containing the C-H, N-H and O-H bonds (Osborne and Fearn, 1986) and water (Sakudo et al, 2006b) that modulate their vibrational modes.…”

Alteration of the vibrational mode has been exploited for distinct metal detection in said agricultural materials (Sauvage et al, 2002;Cozzolino and Moron, 2004;Clark et al, 1987Clark et al, , 1989Saiga et al, 1989;Smith et al, 1991). In this study, Vis-NIR spectroscopy was used to determine native states of metals in tissues espousing organic matrices by comparing vibration mode using partial least squares regression analysis.…”

Native State of Metals in Non-Digested Tissues by Partial Least Squares Regression Analysis of Visible and Near-Infrared Spectra

et al. 2007

-A procedure has been used for the classification and quantification of metals on the basis of a chemometric analysis of visible and near-infrared (Vis-NIR) spectra of metals such as Cu, Mn and Fe in the brain, liver, kidney and testis of mice without digestion. Transmittance spectra in the 600-to 1000-nm region subjected to partial least-squares (PLS) regression analysis and leave-out cross-validation facilitated development of chemometrics models for predicting metal concentration. From the models, Cu, Mn and Fe yielded the coefficients of determination in cross-validation (R 2 VAL ) as 0.8013, 0.9021 and 0.8295 with standard errors of cross-validation (SECV) of 3.399, 0.8237 and 76.512 μg per g tissue, respectively. The respective detection limits of Cu, Mn and Fe were 12.19, 2.616 and 266.32 μg per g tissue. Furthermore, the regression coefficients of the models showed specific patterns for the respective metals. These results suggest that Vis-NIR spectroscopy may have a great potential for analysis of native state of metals in tissues.

“…A necessary first step in this study is the identification of wine industry issues that can potentially be addressed with NMR spectroscopy. Some of these problems include determining the effects of wine on health [6,7], wine origin [8], the type, source, and extent of wine spoilage [9][10][11], the presence of cork taint in wine [12], the concentration and type of sulfides in wine [13], the concentration, source, and type of trace metal contaminants in wine [14], the concentration and type of phenols in wine [15], and finally the relationship between dilute molecular components like aldehydes and flavenoids and wine properties such as age, bouquet, and texture [15]. NMR spectroscopy has already been used to study a limited subset of these problems in detail and most studies either exploit the natural abundance 2 H NMR of native wine samples [16][17][18][19] or apply standard multidimensional NMR pulse sequences to molecules isolated from wine [20,21].…”

A nuclear magnetic resonance (NMR) probe and spectrometer capable of investigating full intact wine bottles is described and used to study a series of Cabernet Sauvignons with high resolution 1 H NMR spectroscopy. Selected examples of full bottle 13 C NMR spectra are also provided. The application of this full bottle NMR method to the measurement of acetic acid content, the detection of complex sugars, phenols, and trace elements in wine is discussed.
