Embodiment 1
[0025] Put 100g of peeled rapeseed into a medium-short wave infrared heating box and heat for 40min at a temperature of 110°C. After cooling to room temperature, transfer to a small high-speed pulverizer for pulverization for 4 minutes. The crushed rapeseed and water were mixed at a ratio of 1:3 (w / w) to obtain a rapeseed mixture, and the mixture was treated with heat and humidity for 25 minutes at a temperature of 90°C. Cool the rapeseed mixture after wet heat treatment to 40°C, adjust the ratio of solid to liquid to 1:5, the pH of the mixture to 9.0, and carry out alkaline extraction for 30 minutes. Add 1.0% (v / w) high temperature resistant protease (300,000 U / g) to the mixed solution after alkali extraction for enzymolysis, the enzymolysis time is 3.0h, the enzymolysis temperature is 60°C, and the enzymolysis pH is 8.0 ; Then centrifuge the enzymolysis solution at a centrifugal speed of 4500r / min for 10 minutes, and centrifuge to obtain free oil 1, emulsified oil, hydrolyz...
Embodiment 2
[0027] Put 100g of peeled rapeseed into a medium-short-wave infrared heating box and heat for 30min at a temperature of 120°C. After cooling to room temperature, transfer to a small high-speed pulverizer for pulverization for 4 minutes. The crushed rapeseed and water were mixed at a ratio of 1:3 (w / w) to obtain a rapeseed mixture, and the mixture was treated with heat and humidity for 25 minutes at a temperature of 100°C. Cool the rapeseed mixture after wet heat treatment to 40°C, adjust the ratio of solid to liquid to 1:5, the pH of the mixture to 9.0, and carry out alkaline extraction for 30 minutes. Add 1.5% (v / w) high temperature resistant protease (300,000 U / g) to the mixed solution after alkali extraction for enzymolysis, the enzymolysis time is 2.5h, the enzymolysis temperature is 70°C, and the enzymolysis pH is 8.5 ; Then centrifuge the enzymolysis solution at a centrifugal speed of 4500r / min for 10 minutes, and centrifuge to obtain free oil 1, emulsified oil, hydroly...
