Sensory guided‐multidimensional gas chromatography: impact of aroma on flavor perception in fruit juices and soft drinks
The objective of the project is to identify aroma compounds responsible for the sensory properties of fruit juices and soft drinks and analyze how they may affect the perception of sweet taste. Close attention will be paid to the interaction between aromas and the chirality of identified compounds in order to study structure-aroma relationships. The ultimate goal of the project is to manipulate aroma sweet perception in an attempt to reduce sugar consumption.
Carmen Barba obtained a B.Sc. in Chemistry from University of Zaragoza, Spain, in 2005. After doing postgraduate studies at Institute of Homogeneous Catalysis – University of Zaragoza (IUCH-UZ) for one year, she went to Madrid to obtain her M.S. and PhD at Institute of Science and Technology of Food and Nutrition in the Spanish National Research Council (ICTAN-CSIC) on the use of multidimensional chromatographic techniques to achieve, at both analytical and preparative scales, enantiomeric resolutions of chiral compounds in complex food samples. During her post-doctoral period at the Public University of Navarre, Spain, in 2012 and the University of Minnesota, USA, in 2013, she adapted her background and acquired new knowledge in the area of food and analytical chemistry, specifically on aroma encapsulation and bitter taste perception. Fellowships supported by AgreenSkills (PCOFUND-GA-2010-267196) and Marie Curie (H2020-MSCA-IF-2014) aims at improving her skills in flavor perception. At present, her research interest is focused on two areas: (i) the development and application of novel analytical methods to extract, separate and identify volatiles compounds in food and beverages and, (ii) the physico-chemical contribution of chiral flavors compounds to the perception.
