Embodiment
[0022] A preparation method of anti-oxidation-low acid value-high-quality rice bran oil, prepared from the following raw materials in parts by weight (g):
[0023] Rice bran 55, alkaline protease 5, activated clay 4, activated carbon 9, L-ascorbyl palmitate 4, fat-soluble rosemary extract 3, appropriate amount of distilled water.
[0024] A kind of anti-oxidation-low acid value-preparation method of high-quality rice bran oil, is characterized in that, carries out according to the following steps:
[0025] a. Pass the rice bran through a 50-mesh sieve, add water to adjust the moisture content to 20%, put it into a heat-resistant plate, spread it to a thickness of 5cm and spread it evenly, put it in a microwave oven, heat it at 800-900W for 180s, take it out, and cool it to room temperature ,spare;
[0026] b. Place the material obtained in a in supercritical CO 2 In the extraction device, at 50-60°C, CO 2 Extract for 2 hours at a flow rate of 50-60kg / h and a pressure of 40-...

Abstract
The invention discloses a preparation method of antioxidant, low-acid-value and high-quality rice bran oil. The preparation method is characterized in that rice bran, alkaline protease, activated clay, activated carbon, L-ascorbyl palmitate, a fat-soluble rosemary extract and distilled water are used as raw materials. Oil in the rice bran is extracted with an aqueous enzymatic method, the aqueous enzymatic method oil extraction technology is safe, environment-friendly and green, and obtained vegetable oil is pollution-free; activated clay and activated carbon are added to decolorize rice bran oil; a supercritical CO2 extraction technology has the advantages of high extraction rate, good selectivity, simple process, no solvent residues and the like and can simplify the rice bran oil refinement process and increase the refinement rate of the rice bran oil; the rice bran oil is deacidified with a molecular distillation technology which is an oil deacidification technology and has the advantages of being low in energy consumption and clean, causing small damage to oil and the like; the antioxidant, low-acid-value and high-quality rice bran oil is obtained.
Description
technical field [0001] The invention relates to a preparation method of rice bran oil, in particular to an anti-oxidation-low acid value-high-quality preparation method of rice bran oil. Background technique [0002] my country is the largest rice producer in the world. Rice bran is an important by-product in the rice processing process, and rice bran has a high oil content and is an important oil source. As a new type of natural vegetable oil, rice bran oil contains a variety of special active ingredients that are beneficial to health. Rice bran oil has the functions of improving immunity, lowering cholesterol, regulating blood lipids, preventing arteriosclerosis, etc., and has high nutritional value. Rice bran oil is increasingly valued and favored by consumers due to its rich nutritional value and health care functions. [0003] Xie Ying used fresh rice bran as raw material in her master's thesis "Research on the Production and Refining Process of Rice Bran Oil", aiming...
