Example Embodiment
[0020] Example 1:
[0021] Take 0.5kg corn germ and grind it in a pulverizer. After pulverizing, pass a 50-mesh sieve. Immediately place the germ granules in a container, evenly spread a layer to make the powder evenly distributed, and then put it into a 0.1kpa autoclave Set the temperature to 110°C for 5 minutes. After the enzyme is inactivated, take out the germ particles, cool them to 60°C at room temperature, and put them in an oven at 60°C to reduce the water content to 9% by mass.
[0022] The crude oil was extracted from the germ particles obtained in Example 1, and the crude oil was found to have the lightest color, 7.3R, 70.0Y. Then the crude oil was refined, the refined oil obtained was stored, and the storage experiment was carried out. The color change of the oil after the sample is stored for 6 months under the normal indoor light environment at 20±5℃, and the change of Lovibond red value |ΔR|<0.3, it can be considered that the above enzyme inactivation method is effec...

[0023] Example 2:
[0024] Take 0.5kg corn germ and grind it in a pulverizer. After pulverizing, pass through a 50-mesh sieve. Immediately place the germ granules in a container, evenly spread a layer to make the powder evenly distributed, and then put it into a 0.2kpa autoclave Set the temperature to 120°C for 5 minutes. After the enzyme is inactivated, take out the germ particles, cool them to about 60°C at room temperature, and put them in a 60°C oven to reduce the moisture to 10%. The crude oil was extracted from the germ particles obtained in Example 2, and the crude oil color was found to be 8.0R, 70.0Y.

[0025] Example 3:
[0026] Take 0.5kg corn germ and grind it in a pulverizer. After pulverizing, pass a 50-mesh sieve. Immediately place the germ granules in a container, evenly spread a layer to make the powder evenly distributed, and then put it into a 0.1kpa autoclave , Set the temperature to 110°C for 1 min. After the enzyme is inactivated, take out the germ particles, cool them to about 60°C at room temperature, and put them in a 60°C oven to reduce the moisture to 12%. The crude oil was extracted from the germ particles obtained in Example 3, and it was found that the crude oil had the deepest color, 9.5R, 72.9Y.
