Multielement stable isotope ratios (H, C, N, S) of honey from different European regions

Investigating the impact of botanical origin and harvesting period on carbon stable isotope ratio values (13C/12C) and different parameter analysis of Greek unifloral honeys: A chemometric approach for correct botanical discrimination

“…Schellenberg et al . (), analysed 516 honey samples of sixteen different botanical origins (acacia, citrus, clover, thyme, sunflower, rape, lavender, honeydew, etc.) collected from twenty European countries, and reported δ 13 C values ranging from −26.70 ± 0.40 (Austrian honey samples) to −24.20 ± 0.30 (Italian honey samples) depending on floral type and geographical origin of honey.…”

“…A considerable number of research studies, apart from the effort to evaluate honey quality and authenticity (Escriche et al ., ; da Silva et al ., ), focuses on honey adulteration using isotopic data (Simsek et al ., ; Tosun, ), while fewer studies use isotopic data for authentication purposes (geographical and botanical discrimination) (Kropf et al .,,b; Schellenberg et al ., ; Dinca et al ., ). As a matter of fact no research study involves isotopic data in combination with other physicochemical parameters, for correct botanical discrimination; neither presents the effect of botanical origin and harvesting year on such parameters, using a chemometric approach.…”

Geographical Origin Characterization of Slovenian Organic Garlic Using Stable Isotope and Elemental Composition Analyses

“…6 For garlic, no databank for tracing its origin at national, continental or global scale has been set up yet, in spite of global utilization of garlic as a condiment in cuisine or for medicinal purposes. 7 Many authors have attempted to determine the geographical origin of different cereal grains, [8][9][10][11] Chinese teas 12 and honey 13 using only stable isotopes of light elements. Samples classification into groups according their geographical origin was relatively successful, indicating that better classification could be achieved by applying not only stable isotope ratios of one or two light elements, but by using multielement stable isotope ratio data.…”

“…The differences in the δ 13 C values could be attributed to differences in local growth conditions e.g., temperature, relative humidity, drought stress, light intensity, and nutrient availability. 10,38 Conversely, δ 34 S is rarely used in such investigations, although sulfur isotopes in plants are known to be related to soil geology 13 and are promoted as valuable indicators for assigning the origin of plant material. 39 Finally, the elemental fingerprint (especially Zn and P) has an even greater discriminating power than the stable isotope ratios.…”

Identification of the Geographical Origins of Pomelos Using Multielement Fingerprinting

“…Therefore, researchers have focused on developing new analytical and detection technologies to verify geographical origins quickly. Many different technologies have been used, such as chemical components (Acquarone and others ; Longobardi and others ), multielement fingerprinting (Yücel and Sultanoğlu ), DNA fingerprinting (Raspor and others ), stable isotope fingerprinting (Schellenberg and others ), and nuclear magnetic resonance (NMR) fingerprinting (Longobardi and others ).…”
