Ever Hernandez Olivas

Post-Doctoral Fellow - Digestion of alternative proteins

Research Interests

Dr Ever Hernandez Olivas postdoctoral fellow with research interests as follows:

In vitro gastrointestinal digestion of foods and food components, especially assessing the impact of different host-related gastrointestinal characteristics (e.g. healthy adults, elderly, infants and patients with cystic fibrosis).
The impact of inherent food characteristics (composition, origin, structure, etc.) on nutrient digestibility.
In vitro bioaccessibility of bioactive compounds and their subsequent impact on human health.
Food processing, preservation and development of new food products by evaluating nutritional, physicochemical, structural and sensory properties.

Current Projects

GIANT LEAPS: Gap resolutIon in sAfety, NuTritional, aLlergenicity and Enviromental assessments to promote Alternative Protein utilization and the dietary Shift

EU project is accelerating the transition from animal-based to alternative dietary proteins to work towards a safe, health-promoting and sustainable food system.
The GIANT LEAPS consortium brings together 34 leading partners from 13 EU member states and 4 associated and affiliated countries (Canada, Serbia, Switzerland, United Kingdom).
