This biogenic content analysis can be useful for the producers as a quality assurance tool, for the customers as feedback about the truly biobased products and for the control organizations as an independent analytical tool to prove the biological origin. More than 100 commercially available foods, cosmetics, and drug samples have been used for biobased carbon content analysis by accelerator mass spectrometry (AMS) 14 C measurement to demonstrate the potential of this technique. Our results show that this measurement technique is a unique tool for the determination of biocontent in foodstuff and medical products. Most of the tested materials were nearly or completely biobased (≥ 98 pMC), and no completely fossil-based final product was detected. The lowest biogenic compound was measured in a vanilla aroma flavor. In 45 of the 102 samples selected a wide range (2–98%) presented fossil-based carbon content. The method can be applied for monitoring raw materials and final products for biobased content in the industry and consumer protection as well.}, year = {2023}, eissn = {1945-5755}, pages = {1176-1192} } @article{MTMT:34134858, title = {Cultural transformations, migration and possible dietary shift during the 2nd Millennia BC in Eastern Central Europe - a bioarchaeological approach}, url = {https://m2.mtmt.hu/api/publication/34134858}, author = {Hajdu, Tamás and Gémes, Anett and Szeniczey, Tamás and Gyenesei, Katalin and Kiss, Krisztián and Fülöp, Kristóf György and Tarbay, János Gábor and Mccall, Ashley and Vicze, Magdolna and Horváth, Anikó and Palcsu, László and Major, István and Molnár, Mihály and Molnar, Erika and Marcsik, Antonia and Pusztainé Fischl, Klára and Szabo, Geza and Mester, Edit and Szeverenyi, Vajk and Kulcsár, Gabriella and Pap, Ildiko and Dani, Janos and Kiss, Viktória}, journal-iso = {AMERICAN JOURNAL OF BIOLOGICAL ANTHROPOLOGY}, journal = {AMERICAN JOURNAL OF BIOLOGICAL ANTHROPOLOGY}, volume = {180}, unique-id = {34134858}, issn = {2692-7691}, year = {2023}, eissn = {2692-7691}, pages = {69-69}, orcid-numbers = {Hajdu, Tamás/0000-0002-3604-1125; Gémes, Anett/0000-0002-5107-8364; Szeniczey, Tamás/0000-0003-1546-7140; Fülöp, Kristóf György/0009-0005-9763-672X; Tarbay, János Gábor/0000-0002-2363-7034; Major, István/0000-0003-4675-9875} } @{MTMT:34129194, title = {Complexity of the Late Bronze Age in the Berettyó-Körös Region (Hungary) in the Light of Carbon, Nitrogen and Strontium Isotopes}, url = {https://m2.mtmt.hu/api/publication/34129194}, author = {Szigeti, Anna and Hajdu, Tamás and Dani, J. and Molnár, E. and Horváth, A. and Marcsik, A. and Márkus, G. and Molnár, Mihály and Major, István}, booktitle = {29th EAA Annual Meeting (Belfast, Northern Ireland 2023) Abstract Book}, unique-id = {34129194}, year = {2023}, pages = {957}, orcid-numbers = {Hajdu, Tamás/0000-0002-3604-1125; Major, István/0000-0003-4675-9875} } @article{MTMT:34075905, title = {Carbon Isotope Investigation of Freshwater Tufa Precipitation in Karst Streams of Bükk Mountains (Hungary)}, url = {https://m2.mtmt.hu/api/publication/34075905}, author = {Bódai, Barbara and Baráth, Balázs Áron and Gergely, Virág and Sóvágó, Dávid and Braun, Mihály and Futó, István and Kele, Sándor and Molnár, Mihály}, doi = {10.14232/jengeo-2023-44749}, journal-iso = {J ENVIRON GEOGR}, journal = {JOURNAL OF ENVIRONMENTAL GEOGRAPHY}, volume = {16}, unique-id = {34075905}, issn = {2060-3274}, abstract = {Recent freshwater tufa precipitation and its parent water were investigated at Szalajka valley, Sebesvíz and Dobrica Spring (Bükk Mts., Hungary). The aim of the study is to analyse the carbon isotope dynamics of freshwater tufa precipitated in karstic streams between the spring water and the first significant tufa barrage using field measurements, water chemistry, and carbon isotope analysis. A further aim was to examine the fossil tufa precipitations in recently active areas and their neighbourhood to determine their age using the 14C method. Based on the 3H content the water samples are relatively young (<10 y). To calibrate the calendar age of older tufas, dead carbon proportion (dcp) were determined in the recently formed freshwater tufas. The lowest dcp of the recent freshwater tufas was estimated at Sebesvíz (9.6±1.3%), the highest at Szalajka (16.4±2.4%) and a moderate value at Dobrica Spring (13.8±2.2%). Due to the rapid decrease in atmospheric 14C level we have to compensate the atmospheric 14C drop between the water infiltration time and the deposition time of fresh carbonates to compensate the bomb-effect. The oldest fossil tufa age (BC 6421-6096) was found at Sebesvíz located around 20 metres away from the riverbed, while the youngest fossil tufa ages (a few years/decades old) were found in the recently active area at all sites.}, year = {2023}, eissn = {2060-467X}, pages = {55-71}, orcid-numbers = {Kele, Sándor/0000-0002-8607-7636} }
