[0145] Experimental Example 3 Optimum Experiment of Process Parameters of Crushing, Extruding and Expanding Pretreatment Process of Raw Materials Before Enzymolysis
[0146] Based on the process of extracting sunflower seed oil and protein by the best water enzymatic method determined in Experimental Example 2, carry out single factor extrusion test, determine each extrusion expansion system parameter (sleeve temperature, die hole aperture, screw speed, material moisture content ) range. Taking the total oil extraction rate as the investigation index, a response surface design experiment with 4 factors and 5 levels was carried out
