    Abstract

    Differences in water activity within multicomponent food systems inevitably lead to moisture (re)distribution phenomena, hence deteriorating textural quality during shelf life. Noninvasive assessment of moisture transport in such systems would promote mechanistic understanding and enable rational development of strategies to control migration. Magnetic resonance imaging (MRI) is an ideal candidate for such a measurement technique, but its use in systems with low-moisture components (e.g., cereal materials) is seriously hampered because of reduced transverse relaxation times. In this work, we report two MRI protocols for the noninvasive and quantitative assessment of moisture transport in multicomponent food products. The first protocol is suitable to study relatively slow (days/weeks) processes, whereas the second one is designed to study fast (hours) moisture transport. We have successfully applied this methodology to quantify moisture transport within multicomponent food systems, with adequate temporal and spatial resolution.
