Background
Dr Landahl is an expert in mechanical properties of fruit and vegetables with extensive experience in non-destructive measurement systems, controlled atmosphere storage and standard destructive textural, biochemical and physiological testing of fresh produce. Her research aims at maintaining quality of fresh produce during storage and developing non-destructive methods for monitoring fruit and vegetables in order to reduce food losses and waste.
She is passionate about applying physics in order to obtain objective data to interpret food quality for human consumption and / or developmental stage of the crop. She is very interested in finding state-of-the-art technology from other areas like medicine, in order to monitor and understand fundamental processes in the plant during storage. In collaboration with industry non-destructive quality testing could be implemented to make a difference to food grading and decrease food waste.
