“…In particular, lanthanides, as well as Y, are significantly different ( p < 0.05) between the Umbrian samples and those from Poland and Africa. The results of previous works suggest the usefulness of these parameters in food authentication [ 36 , 37 ].…”

“…Each sample was constituted by around 30 leaves of tobacco randomly collected In particular, Rb and Tl in primis, followed by Mo, Mn, δ 34 S, La, Y, Co, Na, Pb, Er, As, Bi, and δ 2 H, showed a consistent role in the models aimed at distinguishing the three groups, suggesting their usefulness as markers of geographical origin. Many of the most important variables in the model are REEs, and their potential use as food tracers has already been determined [36,37,40]. It is worth noting that the top rankers of the random forest model are different with respect to the most influential variables found with the Wilcoxon and effect size tests.…”

Elemental and Isotopic Characterization of Tobacco from Umbria

et al. 2021

Umbrian tobacco of the Virginia Bright variety is one of the most appreciated tobaccos in Europe, and one characterized by an excellent yield. In recent years, the Umbria region and local producers have invested in introducing novel practices (for production and processing) focused on environmental, social, and economic sustainability. Due to this, tobacco from Umbria is a leading commodity in the global tobacco industry, and it claims a high economic value. The aim of this study is then to assess if elemental and isotopic compositions can be used to protect the quality and geographical traceability of this particular tobacco. For the first time the characteristic value ranges of the stable isotope ratios of the bio-elements as a whole (δ2H, δ13C, δ15N, δ18O, and δ34S) and of the concentration of 56 macro- and micro-elements are now available, determined in Virginia Bright tobacco produced in two different areas of Italy (Umbria and Veneto), and from other worldwide geographical regions. The ranges of variability of elements and stable isotope ratios had slightly different results, according to the three geographical origins considered. In particular, Umbria samples presented significantly lower content of metals potentially dangerous for human health. The results of this first exploratory work highlight the possibility of characterizing tobacco from Umbria, and suggest widening the scope of the survey throughout Italy and foreign regions, in order to be used to describe the geographical origin of tobacco in general and verify the origin of the products on the market.

“…In order to gauge the effectiveness of the digestion procedure, Polish Certified Reference Material for multielement trace analysis (Oriental Tobacco Leaves CTA-OTL-1) was used, prepared from ICHTJ (Instytut Chemii i Techniki Jadrowej). Digestion was made by adopting the optimized parameters (temperature and power/time steps) suggested by Bettinelli et al (1996). The decomposed samples were diluted to obtain a final volume of 25 mL.…”

Stevia rebaudiana Bertoni is a herbaceous perennial plant originating in the north-east of Paraguay. Its leaves contain low-calorie sweetening agents that can be used as a natural alternative to artificial sweeteners. The leaves are consumed in special human diets and for the treatment of various diseases. The aim of the present work is to study water consumption, yield potential and quality characteristics of this species under different irrigation levels in southern Italy. The field work was carried out in 2006-2007. Irrigation treatments consisted of a control (T100), irrigated with 100% restitution of water consumption and two treatments that received a water depth of 33% (T33) and 66% (T66) of treatment T100. Watering volume was estimated to replenish the soil profile to field capacity for a depth of 0.40 m. The crop was harvested twice a year, and agronomic performance as well as the major cation and glycoside contents (stevioside and rebaudioside A) were evaluated. Overall, the crop coefficients were similar between the two years, although in each year the second growing period showed higher values due to the higher evaporative demand of this period. Interactions of years with irrigation treatments and harvest time were not significant either for yield or yield components. In both cuts the T100 treatments achieved 40% higher leaf dry yield than T33, while T66 showed intermediate values. The harvest index and water use efficiency showed no differences between the two cuts for the same treatments, while the values of both indices decreased with the increase in irrigation regime. Stevioside, rebaudioside A and cation content in the leaves were unaffected by irrigation regime. In order to develop the field cultivation of this species, field experiments are required to prepare a cultivation protocol as well as a genetic improvement program to develop varieties that better respond to the local environment.
