Quality analysis of rapeseed oil crushed with different extruding-expansion pretreatments
We designed and assembled a high-oil extruding-expansion machine which used the dry mode and studied the pretreatment of expansion in oil processing. The interaction between extruder operation parameters and oil quality was obtained by determining the changes of AV (acid values) and POV (value of peroxide) in extruded oil under different extrusion processing conditions. The stability of directly extruded oil was mensurated. The effects of the extrusion system parameters on acid values of extruded oil in turn was temperature of die noddle, diameter of die nozzle, speed of screw, moisture of material, and the effects on POV in turn was moisture of material, temperature of die noddle, speed of screw, diameter of die nozzle. The stability of oxidation of the directly extracted extrusion-expansion oil is higher.
