Personal profile

Research interests

Dr Natalia Rosa-Sibakov (PhD) is a Research Scientist at VTT Food Solutions team. Her research interests focus on the technological but also nutritional properties of dietary fibre and co-passengers. She has a solid knowledge on the structure of cereal dietary fibre (notably arabinoxylan and β-glucan) as well as modification methods (i.e. mechanical and enzymatic) to tailor their functional properties. She has been also working with in vitro digestion models for physiological functionality of ingredients. In addition, she has experience on the application of plant-based ingredients in diverse food products, such as pasta, beverages and yogurt.
