Embodiment 1

[0042] One, a kind of refining process of wheat bran oil and the method for extracting phytosterol by wheat bran oil, it is characterized in that, comprises steps:

[0043] 1) Degumming

[0044] Weigh wheat bran oil and crude oil in a beaker, heat it in a constant temperature water bath at 60°C, and when the oil temperature rises to 40-45°C, add phosphoric acid with an oil weight of 0.8% and a concentration of 85% and 4% distilled water, stir rapidly for 15 minutes, and heat up Keep at 60°C for 1 hour. After the oil is cooled, centrifuge at 3800r / min for 30 minutes, centrifuge twice, and filter to obtain degummed oil;

[0045] 2) Decolorization

[0046] Put the degummed oil in a beaker, heat it in a constant temperature water bath at 90°C, wait until the oil temperature rises to 80°C, slowly add activated clay with a weight of 7% of the degummed oil, decolorize at 90°C for 30 minutes, and wait for the oil to cool down, 3800r / min Centrifuged for 30min, centrifuged twice, filt...

Abstract

The invention discloses a refining technology for wheat bran oil and a method for extracting phytosterol from the wheat bran oil, and belongs to the field of the vegetable oil refinement. The method comprises the following steps: using crude oil of the wheat bran oil as a raw material, to obtain the refined wheat bran oil and the high-purity phytosterol through degumming, decoloring, dewaxing anddeacidifying successively, wherein the deacidifying is performed by using multi-level molecular distillation. The method is capable of, through a mode of the multi-level molecular distillation, respectively acquiring light component grease and heavy component grease. The heavy component grease is the refined wheat bran oil. The light component grease is extracted by using diethyl ether, and the phytosterol is obtained. Namely, the method is capable of realizing the refinement of the wheat bran oil, and acquiring the phytosterol, and remarkable in economic benefit and social benefit.

Description

technical field [0001] The invention relates to the field of vegetable oil refining, in particular to a refining process of wheat bran oil and a method for extracting phytosterols from wheat bran oil. Background technique [0002] Wheat bran is the residual part after extracting wheat flour and germ in the milling process, which accounts for 14% to 19% of the wheat mass. Bran contains rich amylase, protein, phytic acid and other active compounds, and has very prominent If the bran can be fully utilized for deep processing and comprehensive utilization, it will have high economic and social benefits. [0003] In recent years, studies on wheat bran extract at home and abroad have shown that wheat bran extract can effectively control blood sugar and reduce the risk of cardiovascular disease in diabetic patients; regulate the effectiveness and retention of minerals; activate the body to use selenium as The main oxidative stress protection mechanism; various physiological functi...
