[0019] Example 1
[0020] A method for extracting castor oil, which is characterized in that it comprises the following steps:
[0021] (1) Castor plant pretreatment: add water while stirring the castor plant, stir at 125 rpm for 13 min, and adjust the water content to 15-20%;
[0022] (2) Enzymatic hydrolysis: Add 0.3% of the mixed enzyme of cellulase, hemicellulase, protease, α-galactosidase, and β-glucosidase to the above castor oil, and control the enzymatic hydrolysis temperature at 40°C, Enzymatic hydrolysis for 1.5h;
[0023] (3) Microwave treatment: Spread the castor bean seeds flat in the container, control the thickness of the flat layer to 3cm, control the microwave power range to 3500W, the temperature to 130℃, and the microwave treatment for 6min;
[0024] (4) Squeezing: control the temperature to 43℃ for pressing;
[0025] (5) Alkali refining: Add alkali to the castor oil produced by pressing, control the initial temperature at 45°C, and the final temperature at 75°C, alka...
