The invention discloses a method for extracting edible oil from Yuanbao maple fruit, and relates to the technical field of vegetable oil processing. Freeze for 30-60min, then freeze for 2h at room temperature, pulverize to 30 mesh after drying, then pass through enzyme inactivation and enzymolysis, centrifuge at high speed for 15min at a speed of 9800r/min, and separate to obtain Yuanbaofeng edible oil . The extraction method of the invention is environmentally friendly, pollution-free, short in time, high in quality of crude oil, simple in operation, mild in oil extraction conditions, does not damage protein, and low in acid value, phospholipid content and peroxide value of the extracted oil. The water layer and residue obtained after centrifugal separation contain recyclable substances such as soluble polysaccharide, protein and tea saponin, which reduces the generation of sewage and waste compared with traditional processes. |
