Emerging Thermal and Non Thermal Food Processing
Last Updated: 2026-06-01 11:31:17
Abstract
This course is built on the holistic approach in sustainable food processing via the consideration of the total value chain. Selected mechanical, biotechnological, thermal and non-thermal techniques for best biomass and energy use efficiency will be investigated. Focused technologies are new thermal processes, high pressure techniques, electroporation and different radiation based sources.
Objective
Understanding of selected emerging food processing concepts with focus on lower process intensity for healthy and high quality food production, waste reduction as well as biomass and energy use efficiency. Updates from academia and industry around new trends in food process development
Content
Emerging combined processes based on mechanical, thermal and non-thermal techniques, Multi hurdle technology concept for preservation, Extreme high temperature-short time processes, high pressure techniques, electroporation, radiation, Biorefineries based on emerging process elements, Ongoing industry initiatives
Resources
Lecture Notes
Script will be distributed before the course via Moodle.
