Abstract

The invention discloses a method for extracting oat bran oil by using a supercritical CO2 (Carbon Dioxide) fluid technique. (1) a supercritical CO2 fluid serves as an extraction agent, and extraction is carried out on oat bran under conditions of 20-35MPa of extraction pressure, 40-48 DEG C of extraction temperature, 533-750ml / min of supercritical CO2 fluid flow; and (2) the oat bran oil is obtained through separation under conditions of 5-9 MPa of separation pressure and 50-60 DEG C of sepeartion temperature. An oil obtaining rate of the oat bran oil extracted by using the supercritical CO2 fluid technique can achieve more than 8%, the oat bran oil is slightly yellow in oil color and high in purity, and the method is simple in operation, soft in reaction condition and free of any pollution.

Description

technical field [0001] The invention relates to a preparation method of edible oil, in particular to an extraction method of oat bran oil, especially by using supercritical CO 2 Process for fluid extraction of oat bran oil. Background technique [0002] Oatmeal has extremely high nutritional value, oat fat is high-quality fat, including 82.17% unsaturated fatty acid, 13% protein, 2.7% soluble dietary fiber, 0.046% calcium, 0.249% phosphorus, 0.031% iron, 0.029% selenium, magnesium 0.071% and fat 9%, etc. These ingredients are far more than other food crops, and it also includes 18 kinds of amino acids such as leucine, arginine, lysine, active peptides and a large amount of minerals, and the ratio is very suitable for human beings, and it is more beneficial to the human body than other crops. healthy sex. Oats are widely praised as a highly nutritious and medicinal food. [0003] Oat bran, a by-product of oat rice processing, has not been effectively utilized. The oil-so...
