Associate mr. sc. Renata Leder, form Department of Viticulture and Enology of Croatian Centre for Agriculture, Food and Rural Affairs on June 2016 finished her short-term training at Department of Environmental Sciences Institute “Jožef Stefan” in Ljubljana, Slovenia, with the aim of improving knowledge in the field of stable isotope analysis of olive oil.
Training was led by Prof Nives Ogrinc, whose area of work and research is related to the application of geochemistry and stable isotopes in different areas. In the area of food, she investigated the application of stable isotopes as markers for origin and authenticity of various foods, such as honey, olive oil, wine, milk and fruit juices. She has published more than 110 papers and 10 book chapters, and her work has been recognized through more than 730 citations. She coordinated several national and international projects.
MSc Leder with Prof Ogrinc
As one of the partners of spec-T-oil Project, ZVV-HCPHS will participate in determining the isotopic ratio 13C/12C in samples of olive oil by mass spectrometry. During training, temes that MSc Leder explore were; (I) the ratio of the theory and applications of stable isotopes 13C / 12C in the olive oil, (ii) sample preparation and analytical sequence analysis of the olive oil, (iii) the type and application of the reference materials, (v) examination of the various analytical techniques for the determination of stable isotopes in food and environment (GC-C-IRMS, OH / CNS) and (vi) review of studies using various techniques (GC-MS, GC-IT-MS, ICP-MS, LC-Qtrap, LC-QTOF) aimed at determining the adulteration of food and the quality of the environment

Suradnica mr. sc. Renata Leder, dipl. ing. iz Zavoda za vinogradarstvo i vinarstvo Hrvatskog centra za poljoprivredu, hranu i selo usavršavala se u području analitike stabilnih izotopa maslinovog ulja na Odsjeku za znanosti o okolišu Instituta „Jožef Stefan“ u Ljubljani, Slovenija.
Usavršavanje je vodila prof. dr. sc. Nives Ogrinc, čije je područje rada i istraživanja vezano uz geokemiju i primjenu stabilnih izotopa u različitim područjima. U području hrane je istraživala primjenu stabilnih izotopa kao markera izvornosti odnosno porijekla i autentičnosti različitih namirnica, kao što su med, maslinovo ulje, vino, mlijeko i voćni sokovi. Objavila je više od 110 radova i 10 poglavlja u knjigama, a njezin je rad prepoznat i kroz više od 730 citata. Koordinirala je više nacionalnih i međunarodnih projekata te oranizirala nekoliko konferencija/simpozija.
Kao jedan od partnera na ovome projektu ZVV-HCPHS će sudjelovati kroz određivanje izotopnih omjera 13C/12C u uzorcima maslinovog ulja masenom spektrometrijom. Tijekom usavršavanja Mr.SC Leder se podrobnije upoznala sa sljedećim temama; (i) teorija i aplikacija omjera stabilnih izotopa 13C/12C u maslinovom ulju, (ii) priprema uzorka i analitičke sekvence pri analizi maslinovog ulja, (iii) vrste i primjena referentnih materijala, (v) pregled raznih analitičkih tehnika za određivanje stabilnih izotopa u hrani i okolišu (GC-C-IRMS, OH/CNS) te (vi) pregled istraživanja raznim tehnikama (GC-MS, GC-IT-MS, ICP-MS, LC-Qtrap, LC-Qtof) usmjerenim na utvrđivanje patvorenja hrane te kvalitetu okoliša
