“…The first PC has high loadings for Li (0.919), Mn (0.905), and Rb (0.957), and could represent the geological influence upon sample distribution. This is in good accordance with our previously published works [ 18 ], in which Li and Mn were found to be among the most representative markers for the geographical origin. The same PC has moderate loadings for Al (0.886) and for Cd (0.850), while the second PC has only one high value for As (0.940) and a moderate value for Se (0.864).…”

“…Compared to other matrices, such as vegetables, fruits, and honey [ 18 , 20 , 21 , 22 ], the differentiation of fruit distillates, with respect to various criteria, such as geographical or botanical origins, based on isotope and elemental content, is not straightforward. This is mainly due to the extensively technological processes in which these products undergo, affecting the original fingerprint of the raw materials (i.e., fruits), and inducing, especially in the case of the elemental profile, a producer signature.…”

The potential association between stable isotope ratios of light elements and mineral content, in conjunction with unsupervised and supervised statistical methods, for differentiation of spirits, with respect to some previously defined criteria, is reviewed in this work. Thus, based on linear discriminant analysis (LDA), it was possible to differentiate the geographical origin of distillates in a percentage of 96.2% for the initial validation, and the cross-validation step of the method returned 84.6% of correctly classified samples. An excellent separation was also obtained for the differentiation of spirits producers, 100% in initial classification, and 95.7% in cross-validation, respectively. For the varietal recognition, the best differentiation was achieved for apricot and pear distillates, a 100% discrimination being obtained in both classifications (initial and cross-validation). Good classification percentages were also obtained for plum and apple distillates, where models with 88.2% and 82.4% in initial and cross-validation, respectively, were achieved for plum differentiation. A similar value in the cross-validation procedure was reached for the apple spirits. The lowest classification percent was obtained for quince distillates (76.5% in initial classification followed by 70.4% in cross-validation). Our results have high practical importance, especially for trademark recognition, taking into account that fruit distillates are high-value commodities; therefore, the temptation of “fraud”, i.e., by passing regular distillates as branded ones, could occur.

“…Furthermore, the flora consumes this water, however as a result of transpiration it gradually enriches this water with 2 Н and 18 О, leading to introduction of these isotopes into organic compounds [23,24]. This, for instance, explains the significant difference in isotopic composition of juices freshly squeezed from fruits and vegetables grown in various geographic regions [25,26,27]. In its turn water in healthy animal tissues is enriched with isotopes from two main sources: ingested/drinking water and water formed during oxidation of reducting equivalents during the metabolism of food substrates, including the reduced form of nicotinamide adenine dinucleotide (NAD) in the mitochondrial respiratory chain [28,29,30,31].…”

Deuterium-Depleted Water Influence on the Isotope 2H/1H Regulation in Body and Individual Adaptation

et al. 2019

This review article presents data about the influence of deuterium-depleted water (DDW) on biological systems. It is known that the isotope abundances of natural and bottled waters are variable worldwide. That is why different drinking rations lead to changes of stable isotopes content in body water fluxes in human and animal organisms. Also, intracellular water isotope ratios in living systems depends on metabolic activity and food consumption. We found the 2H/1H gradient in human fluids (δ2H saliva >> δ2H blood plasma > δ2Hbreast milk), which decreases significantly during DDW intake. Moreover, DDW induces several important biological effects in organism (antioxidant, metabolic detoxification, anticancer, rejuvenation, behavior, etc.). Changing the isotope 2H/1H gradient from “2H blood plasma > δ2H visceral organs” to “δ2H blood plasma << δ2H visceral organs” via DDW drinking increases individual adaptation by isotopic shock. The other possible mechanisms of long-term adaptation is DDW influence on the growth rate of cells, enzyme activity and cellular energetics (e.g., stimulation of the mitochondrion activity). In addition, DDW reduces the number of single-stranded DNA breaks and modifies the miRNA profile.

“…In the treatments 6-13 the same soil substrate were used like in the treatments 2-5, whereby there were added earthworms (Eisenia fetida). The pairs of treatments 6 and 7, 8 and 9, 10 and 11, 12 and 13 contained the identical substrates as the treatments 2, 3, 4 and 5, whereby 10 individuals of red worm was added to the treatments of the even number (8,10,12) and 20 individuals of red worm was put into the treatments of the of the odd number (9, 11, 13) (Table 2-5).…”
