Ethyl butanoate, methional in neutral/basic fraction and ethanoic, butanoic and hexanoic acids in the acidic fractions appeared to be the most potent odour-active compounds. The detection of odour-active compounds by this study may be promising for the certification of traditional yoghurt products as Protected Designation of Origin.eninfo:eu-repo/semantics/closedAccessTuzlu Yoghurtvolatilesodour-active compoundsgas chromatographyolfactometryArticle205364136482-s2.0-53949093020Q4WOS:000259602500044Q4
