Abstract
Over the last decades, consumer preferences have favored healthier and more flavorsome food with higher nutritional value: the driving force has been food quality. Although the primary condition for food quality is safety, an equally important role is played by its sensory impact, in particular flavor and appearance. Food constituents with their peculiar quali-quantitative distribution concur to define a characteristic chemical fingerprint which encrypts comprehensive information on nutritional properties, sensory attributes, quality, authenticity and safety. Modern omics disciplines, as food metabolomics and sensomics [1,2], are the elective strategies for a comprehensive evaluation of food attributes, they combine multi-dimensional analytical approaches in sensu lato to include in the investigation all constituents considered collectively (primary and specialized metabolites, compounds generated by thermal treatments and/or enzymatic activity, flavour active compounds). High quality hazelnuts (Corylus avellana L.) from different botanical/geographical origin are here considered as challenging test bench for multidimensional investigations while trajectories from Academic research to industy application will be discussed as virtuous interactions to achieve a modern concept of food quality. Targeted and un-targeted fingerprinting [3,4] aiming to reveal hazelnuts aroma potential, to define aroma blueprint or spoilage traits will be presented emphasizing the advantages of a true multidimensionality, from sample preparation (the zeroth dimension of an analytical system) to separation (two-dimensional comprehensive chromatography) and analyte detection and identification (mass spectrometry). Reliable, effective and intuitive data analysis approaches conclude the analytical investigation enabling a productive and comprehensive interpretation of the complex information array in particular by linking analytical data to hazelnut quality attributes. Computer Vision and Artificial Intelligence smelling [5] might be effective decision makers with strong correlation to distinctive chemical patterns. References 1.
