Barbora Dubovcova

Barbora Dubovcova is in the lead of Food Safety for Low Energy Electron Beam Business at Bühler AG, Uzwil, Switzerland since 2016. She is in charge of validating and scaling of the innovative technology for the dry food industry and its implementation to the HACCP.
She is fostering innovation and closing the gap between scientific research and industrial application by collaborations with universities and research institutes in the field of food safety and microbiology.
Barbora holds a degree in Food Technology from the Danish Technical University (DTU) where she carried out research on non-thermal bacteria reduction technologies in collaboration with Swiss Federal Institute of Technology in Zurich.

Abstract

Presence of pathogenic bacteria on low-moisture foods such as spices and rising consumer demand for fresh and minimally processed products create opportunities for surface decontamination technologies such as low-energy electron beam technology. LEEB treatment efficiently reduces natural bioburden, thermo-resistant bacterial spores and Salmonella spp. to safe levels. This presentation discusses the main considerations prior to the microbial validation, incl. selection a suitable surrogate organism and other parameters which have an impact on the success of validation and implementation of this technology to practice.

François Vander Stappen

With a background in electronic engineering and in medical physics, François started working for IBA 12 years ago, in proton therapy. After getting a deep experience on the field, he worked in R&D and led several research programs, aimed at improving the treatment accuracy. 

He joined in early 2020 the IBA Industrial business unit in the product management team. He works at developing a research program in collaboration with Aerial, bringing his experience of medical irradiations to the industrial domain. 

Abstract

Monte Carlo is the state-of-the art technique for the simulation of particle transport, of their interactions with matter, and the dose deposition. It allows to predict the achievable dose uniformity depending on the irradiation parameters and the product properties. An excellent agreement with measurements has been shown. 

In this presentation we will show the potential of simulations, and use them to analyse the dose uniformity ratio for various configurations of products. We will compare the achievable uniformity in E-beam and X-ray. Specifically, we will study the impact of the density, shape and arrangement of food products like fruits and fresh vegetables.
