Abstract

The invention discloses a method for extracting acer truncatum fruit edible oil, and relates to the technical field of vegetable oil processing. The method comprises the steps: shelling the acer truncatum fruits to obtain acer truncatum seeds, putting the acer truncatum seeds into a low-temperature freezer, carrying out freezing treatment for 30-60 minutes at the temperature from -130 DEG C to -160 DEG C, then, carrying out unfreezing for 2 hours at normal temperature, carrying out drying, then carrying out crushing to 30 meshes, then carrying out enzyme deactivation and enzymolysis, carryingout high-speed centrifugation for 15 minutes at a rotating speed of 9800 r / min, and carrying out separation to obtain the acer truncatum edible oil. The extraction method disclosed by the invention isenvironment-friendly, pollution-free, short in time and high in crude oil quality; the oil extraction process is simple and convenient to operate, oil extraction conditions are mild, protein cannot be damaged, the acid value, the phospholipid content and the peroxide value of the extracted oil product are low, a water layer and residues obtained after centrifugal separation contain recyclable substances such as soluble polysaccharide, protein and tea saponin, and compared with a traditional process, the method reduces sewage and waste.

Description

technical field [0001] The invention relates to the technical field of vegetable oil processing, in particular to a method for extracting maple ingot edible oil. Background technique [0002] Yuanbao maple is a unique tree species in my country and belongs to the deciduous tree of the Aceraceae family. It is distributed in Heilongjiang, Liaoning, Beijing, Inner Mongolia, Jilin, Hebei, Henan, Shandong, Shanxi, Shaanxi, Yunnan, Gansu, Ningxia and other places in China. Yuanbao maple leaves are rich in flavonoids, chlorogenic acid and other active ingredients, and the inner testa of Yuanbao maple contains 60% high-quality condensed tannins. The oil content of Yuanbao Maple Seed Kernel is as high as 48%, and the unsaturated fatty acid content in the oil is as high as 92%. And it is a double-effect magical substance that promotes nerve cell regeneration, and has significant anti-fatigue, anti-aging, and blood-fat-lowering effects. Studies have shown that the vitamin E content ...
