Mapping of water mobility and localisation in multi-component foods

Objectif

Water is well recognised as a critical ingredient in the structuring of food products. Many of the processes involving interactions of water with food ingredients are well understood, and the basic principles are used by cooks and food technologists to address consumer preferences and needs.

In the last years, however, we have witnessed dramatic changes in behaviour of consumers. More and more food products are consumed in Out-of-Home channels and in their own homes, consumers desire shorter preparation times for healthy and fresh meals.

In the development of products that address these consumer needs, control over moisture content and migration during processing and storage is critical to both product quality and safety. The current measurement and tools are inadequate in providing the structural information that is needed for understanding of the kinetic aspects of water redistribution phenomena.

In order to design new products there is a need for integrated measurement and modelling tools with which we can understand and predict water redistribution in complex food materials. MRI could be a suitable technique for non-invasive assessment of water mobility, but in its current form it is hampered in the observation of water in domains with low molecular mobility.

Hence, it is proposed to overcome this limitation by introducing MRI methods that can assess the full range of molecular motilities that one can encounter in food products. The MRI tools will be deployed in conjunction with modelling of water redistribution in order to get a good understanding of the underlying physical phenomena.
