Rice Bran Oil Extraction Solvent Process, Flow Chart
We have to mention that hot extraction method which would obtain more oil yield and purer edible oil than the cold pressing method. When refers to Rice bran oil production, the following three processing steps are important they are raw material preparation, Rice bran oil extraction, and crude oil refining. Rice bran raw material preparation:

Processing Technology of Rice Bran Oil, ScienceDirect
Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%–20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids ( Tao, 1989 ; Houston, 1972 ; Saunders, 1986 ).

Optimization of Physical Refining to Produce Rice Bran Oil
Crude rice bran oil (RBO) is rich in valuable minor components such as tocotrienols, phytosterols and γ-oryzanol. These compounds are well preserved during physical refining, but in current industrial practice, RBO is mostly refined chemically because this results in a lighter color. However this process removes most of the γ-oryzanol. The challenge is to develop a refining process which

Bioactives from Crude Rice Bran Oils Extracted Using Green
Crude rice bran oils from different rice cultivars and extraction methods bear different contents of nutraceuticals. The health benefits of lowering cholesterol activity of rice bran oil being confirmed by many reports are partly attributed to non-nutrient nutraceuticals, especially γ-oryzanol, phytosterols, and policosanols. As the world has been facing the global warming crisis, green
1) Firstly, to pump crude rice bran oil into oil refining tank with heat conduction oil, and the temperature will reach about 70°C-80°C in one hour, then add acid or alkali to separate rice bran oil according to the acid value.
- What is the first step in refining rice bran oil?
- In industrial production, rice bran oil is mostly refined by hydration degumming, active clay decolorization, steam deacidification and deodorization, and low-temperature freezing dewaxing. The specific method is to add 2¡ë~3¡ë phosphoric acid and a proper amount of water to treat the crude rice bran oil at 90 °C for degumming.
- What is deacidification of rice bran oil?
- Deacidification is the process of removing free fatty acids from crude rice bran oil. This process can be achieved through various methods such as alkali refining, distillation, mixing, re-esterification, and extraction. Among these, alkali refining has comprehensive effects like deacidification and decolorization, but it results in higher refining loss.
- What are the by-products of refining rice bran oil?
- The refining processes of rice bran oil products generate various types of by-products, including gum, rice acid oil, and rice wax. The refining processes are the main factor causing the loss of nutraceuticals into the by-products, especially the loss of PC into rice bran wax and the loss of phytosterol into rice acid oil.

- How is rice bran oil extracted?
- Rice bran oil is extracted from rice bran, which contains about 15¨C20% crude oil. The extraction methods include pressing, solvent extraction, supercritical carbon dioxide extraction, and enzymatic extraction.
- Is rice bran oil a nutraceutical?
