13C/12C pattern of honey from Turkey and determination of adulteration in commercially available honey samples using EA-IRMS
TL;DR: In this paper, the authors reported (13 C/12 C, 12 C, ǫ) patterns of 31 authentic honey samples obtained from different sources and regions of Turkey as well as 43 commercial honey samples to determine the adulteration using mass spectrometer coupled to elemental analyzer (EA-IRMS).
Journal ArticleDOI
HPLC and LC-MS/MS methods for determination of sodium benzoate and potassium sorbate in food and beverages: performances of local accredited laboratories via proficiency tests in Turkey.
