Characterizing the relationship between aroma profiles and odour perception in northern highbush blueberries

Blueberries consumption has increased in the last decades due to their delicious flavour and recognized health benefits. However, even if the blueberry flavour is naturally delightful, some consumers are concerned because this flavour is not consistent over weeks, which could result in a decreased purchasing interest. Blueberry flavour depends on many factors, especially the genetic and pre-/post-harvest factors. Cultivar selection is one of the most effective ways to modulate blueberry flavour, but berry breeders need to know which specific compounds they should regulate. Through a unique combination of chromatographic and olfactometric-mass spectrometric analyses, this project aims to determine which are the most impactful aromas from the hundreds of volatile compounds identified using instrumental techniques. The outcomes of this project could be used to understand the mechanisms driving the consumer preference in sensory studies and to assist in the prospective development of new selections with consistent flavour and enhanced marketability.
