Optimising electrohydrodynamic drying of cellular foods

The core of this project is the simulation-based design and subsequent fabrication of a lab-scale setup to investigate and optimise EHD drying of cellular food tissue. The principle behind electrohydrodynamic (EHD) drying is that airflow is generated by means of corona discharge, so- called ionic wind. This ionic wind enhances heat and mass transfer from any wet material that is placed in this airflow field. As electrohydrodynamic drying is a non-thermal technology, it is particularly attractive to dehydrate heat-sensitive products, such as cellular foods (e.g. fruit). Compared to conventional convective drying, it has been reported to reduce drying time, reduce product shrinkage, increase rehydration capacity, improve (soften) texture, and preserve color and flavor better. It is also found to preserve better the nutritional content (vitamin C).

Optimisation of fruit cold chains using fruit simulators

The core of this project is to better maintain fruit quality in the postharvest cold chain, including by designing and manufacturing an optimised fruit simulator. Optimising fruit cold chains across all the unit operations is of key importance to maintain fresh fruit quality and to reduce food losses. Temperature and the gas composition in the air (H2O, O2, CO2, C2H4) are affecting decay and fruit quality, so need to be controlled during precooling, refrigerated transport and cold storage. Moreover, by tuning these environmental parameters to a specific fruit species, shelf life can be maximised.

Seed Sustainability Thesis Projects

In collaboration with the ETH Seed Sustainability platform, which is organized through ETH Sustainability, the WFSC has supported Bachelor and Master thesis projects on sustainable food system themes. Seed Sustainability acts as a link between research-related questions from business and society and the research interests of universities.

Opportunities with WFSC Members

Center members also offer opportunities for students to complete theses on topics of relevance to the world food system, and the Center is able to offer support to facilitate the integration of these students into the WFSC network and activities.

Students looking for thesis projects on food systems topics may contact the WFSC or the WFSC Members directly to learn about possible openings.

Students who are interested in PhD theses opportunities with our Center or on food system topics should please see our Open Positions page.
