ABSTRACT
In this talk, we present four recent applications of Near-infrared (NIR) Spectroscopy and Hyperspectral Imaging (HSI) combined with chemometrics for food and biological systems. Although the applications differ in objective, data structure, and analytical complexity, they all share the same underlying technological framework based on spectroscopy and multivariate data analysis.
The selected case studies cover a wide range of real-world problems: detection of animal by-products in bone ashes, prediction of fungal infection sensitivity in tomato sepals, estimation of macronutrient composition in fresh cheeses, and identification of adulteration in honey. Each study involves distinct datasets and modeling strategies tailored to the specific analytical challenge, ranging from classification to regression tasks.
BIOGRAPHY
Dr. Mercedes Bertotto holds a Master’s degree in Food Science and Technology, as well as a Doctorate in Engineering from the University of Buenos Aires. She worked for 12 years at the National Reference Laboratory (SENASA, Argentina), where she was responsible for NIR spectroscopy and chemometric analysis. She later worked as a Researcher in Spectral Sensing and Chemometrics at Wageningen University & Research, focusing on hyperspectral imaging and advanced data analysis for food quality and safety. She currently serves as a Lecturer in Data Science at Wittenborg University of Applied Sciences and is the founder of Vibralytics, a consultancy specializing in spectroscopy and chemometrics.
Dr. Bertotto has participated in more than 15 international conferences, delivering oral presentations, invited lectures, and posters at major events such as ICNIRS. Her work has received international recognition, including the SENASA First Prize and the John Shenk Travel Award.
