Embodiment 1

[0028] A rice bran oil extraction and purification technology, comprising the steps of:

[0029] (1) Rice bran pretreatment:

[0030] Put the rice bran into the steam explosion machine for steam explosion treatment. After completion, take it out and put it in the drying box for drying treatment. After the overall water content of the rice bran drops to 22%, take it out, and then put it into the microwave processor for microwave treatment. After 4 minutes, take out the rice bran for later use;

[0031] (2) Extraction of rice bran oil:

[0032] Mix the rice bran treated in step (1) with the leaching solvent according to the ratio of solid to liquid 1:4, adjust the overall pH value to 6.5~7.0, then add neutral protease with 0.15% of the total mass of rice bran and 7 times of clear water, Continuously stirring and extracting for 5 hours to obtain an extract, then separating oil from water, and finally distilling and removing the crude rice bran oil after the extraction solvent f...

Abstract

The invention discloses a rice bran oil extraction and purification technology. The rice bran oil extraction and purification technology comprises the following steps: (1) pre-treating rice bran; (2)extracting rice bran oil; (3) purifying the rice bran oil. The rice bran oil extraction and purification technology is reasonably improved so that the whole extraction and treatment efficiency is improved and the processing cost is low; the oil yield is improved by about 10 percent; the obtained rice bran oil has few impurities and high conditions and has very strong market competitiveness and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of rice bran oil processing, and in particular relates to a rice bran oil extraction and purification technology. Background technique [0002] Rice bran is a by-product of rice processing, with an oil content of 15-22%, and rice bran oil is a high-quality edible oil containing glycolipids, glycoproteins, fatty acids and other lipids, which can promote human growth; , Anti-thermal oxidation and other advantages, known as "healthy oil", "nutritious oil", has a very good market prospect. In the prior art, the solvent extraction method has a higher oil yield than the other two methods, and is easy to produce on a large scale, so it has strong applicability. However, in the prior art, the rice bran oil produced by the solvent leaching method has the characteristics of darker color, and the production process consumes a lot of energy, and the extraction of rice bran oil is incomplete and contains more impurities...
