Contribution of cellular structure to the large and small deformation rheological behavior of kiwifruit
The relative contribution of turgor pressure, cell wall and middle lamellae to the rheology of kiwifruit was studied by performing large deformation assays and using an empirical model proposed by our group. Results were compared with those obtained previously through dynamic testing. Initial (σo) a...
