Abstract

The invention relates to the technical field of grease extraction processes, in particular to a method for extracting acer truncatum oil by combining ultrahigh pressure with a subcritical extraction technology. The method comprises the following steps: selecting raw materials; shelling: selecting acer truncatum seeds; crushing; ultrahigh-pressure treatment: performing ultrahigh-pressure treatmenton the acer truncatum seed powder under certain conditions; subcritical extraction: weighing about 100-300g of powder, putting the powder into a material bag, putting the material bag into a subcritical extraction tank, and vacuumizing the extraction tank until the vacuum degree is -0.1 Mpa; taking butane as an extracting agent, and extracting for 3-5 times under the conditions that the extractiontemperature is 20-50 DEG C, the extraction time is 30-120 minutes; and separation: after the extraction is finished, introducing the extraction liquid into a separation tank, reducing the pressure to-0.1 Mpa, and separating butane from the acer truncatum oil to obtain the acer truncatum oil. The extraction time is short; the energy consumption is low; and the oil yield is high.

Description

technical field [0001] The invention relates to the technical field of oil extraction technology, in particular to a method for extracting Yuanbao maple oil by using ultra-high pressure combined with subcritical extraction technology. Background technique [0002] Yuanbao maple is a tree of the Aceraceae family, and the wing fruit resembles Yuanbao. Yuanbaofeng is a unique tree species in China, with many and large fruits, and a wide distribution range. Yuanbaofeng is full of treasures, and its seed kernels, seed coats, pericarp including fruit wings and leaves are all valuable forest resources. Its seeds are rich in oil and protein, and the oil is rich in essential fatty acids and fat-soluble vitamins. In recent years, studies have found that Yuanbao maple oil can not only inhibit tumor cells, but also promote the growth of new tissues, and has the effect of repairing somatic cells. Therefore, Yuanbao maple oil is not only a high-quality edible oil, but also a health care...
