Abstract:
Cereal processing plays a crucial role in food security by enhancing the bioaccessibility of bioactive compounds and improving protein digestibility. In this study, we applied integrated untargeted metabolomics and proteomics approaches using UHPLC-ESI-Q-TOF mass spectrometry with data-independent acquisition (DIA) to comprehensively assess the impact of different processing strategies—including pearling, cooking, extrusion, and germination—on the phenolic profile and protein composition of cereals, with particular emphasis on sorghum grains.
By combining advanced omics technologies with in vitro digestion models, we investigated how processing modulates the bioactive landscape and influences the bioaccessibility of health-promoting compounds. Our findings provide new insights into the molecular transformations occurring from raw grain to processed product, supporting the development of sustainable cereal-based foods with enhanced nutritional and functional properties.
Short Bio:
Mariana Ferreira earned her degree in Food Engineering from the University of São Paulo (USP), Brazil, and completed her Ph.D. in Chemistry, Biochemistry, and Food Technology at the Institute Agro Montpellier, France (2011). Since 2013, she is Professor at the Federal University of the State of Rio de Janeiro (UNIRIO) in the Department of Science and currently Director of the Center of Innovation in Mass Spectrometry (IMasS) at the same university. She is Scientist Fellow at FAPERJ (Foundation for Research Support of State of Rio de Janeiro) and at CNPq (National Council for Scientific and Technological Development).
Dr. Larraz is a dedicated researcher who has been a collaborator of the Center for Innovation in Mass Spectrometry since its inauguration in 2013. Her work focuses on the application of advanced mass spectrometry techniques to investigate the metabolomics and proteomics of food systems. She has a particular research emphasis on cereal metabolomics, aiming to unravel the complex biochemical profiles of grains. Her research is highly collaborative, featuring extensive work with diverse national and international partners, notably including INRAE in France, University of Granada (Spain) and the Metabolomics Core Facility (MetCore) at the Universidad de los Andes in Colombia.
