In order to study the force-structure and oil out property of sunflower seed kernel under compressive loading during processing, the force-structure properties of sunflower seeds under different compression distance, compression speed, holding time and temperature were investigated by texture analyzer combined with in-situ optical microscopic observation for compression test on sunflower seeds. The sunflower kernel damage was analyzed with the FEM method. The results showed that the extrusion force of the sunflower seed kernel increased with increasing compression distance. Due to the weakest ...
