Embodiment 1

[0026] The crude oil from which impurities have been filtered out is heated up to 60°C by a spiral plate heater, and then a compound degumming agent is added. The compound degumming agent is a mixture of 0.2% of crude oil weight with 10% oxalic acid solution and 0.6% of crude oil weight with 6% NaCl solution, and the compound degumming agent is heated to 75°C in advance. The oil is mixed with the compound degumming agent for 35 minutes, and then enters the centrifuge to remove the colloid. After degumming, the oil enters the crystallization tank to cool to 10°C, the cooling rate is controlled at 2°C / h, the stirring speed is controlled at 10r / min, and the stirring is turned off after the oil temperature drops. After 72 hours of crystal growth, the oil enters the filter press to filter out wax. The dewaxed oil is firstly heated to 80°C by a heat exchanger and then enters the thin film evaporator. The vacuum degree of the thin film evaporator is 0.095MPa. After evaporating water ...

Embodiment 2

[0030]The crude oil from which impurities have been filtered out is heated to 65°C by a spiral plate heater, and then a compound degumming agent is added. The compound degumming agent is a mixture of oxalic acid solution with a volume concentration of 0.5% of the crude rice oil weight of 14%, and a NaCl solution of 0.8% of the crude rice oil weight and a volume concentration of 8%, and the compound degumming agent is heated to 80°C in advance. The oil is mixed with the compound degumming agent for 30 minutes, and then enters the centrifuge to remove the colloid. After degumming, the oil enters the crystallization tank to cool to 15°C, the cooling rate is controlled at 2°C / h, the stirring speed is controlled at 10r / min, and the stirring is turned off after the oil temperature drops. After 72 hours of crystal growth, the oil enters the filter press to filter out wax. The dewaxed oil is first heated to 80°C by a heat exchanger and then enters the thin film evaporator. The vacuum ...

Abstract

The invention belongs to the field of rice oil processing, and provides a preparation process of nutritional rice oil rich in oryzanol and vitamin E. The preparation process is mainly characterized in that a conventional rice oil refining process is improved, technological processes of crude rice oil filtering, compound degumming, dewaxing, molecular distillation, degreasing and obtaining of finished product rice oil are adopted, and nutrient substances such as oryzanol, vitamin E and the like in rice oil are reserved to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of rice oil development and application, and in particular relates to a preparation process of nutritious rice oil rich in oryzanol and vitamin E. Background technique [0002] Rice is the largest grain variety in my country. In 2014, the annual output was about 172 million tons, accounting for 42% of the country's total grain output, and the world's rice production accounted for 37% of the total grain output. In the process of processing rice into polished rice, the outer shell and about 10% of the total weight of the seed coat, pericarp, perisperm, paste layer and germ must be removed, which is the main by-product of rice processing - rice bran. [0003] Rice oil is a kind of vegetable oil produced from rice bran by pressing or leaching. Rice bran contains 18% to 25% oil and has high nutritional value. The healthy nutritional oil is deeply loved by people with hyperlipidemia and cardiovascular and cerebr...
