Research Scientist

Dr. Lamia L'Hocine's research activities focus on food proteins with a particular interest in plant proteins (from oilseeds, legumes and cereals), their extraction and characterization and evaluation of the impact of processing on their extractability, molecular, nutritional, functional and allergenic properties, as well as on their digestibility and bioavailability. Her research aims to add value to the protein ingredients and study the feasibility of new protein ingredients in various food applications.
