Rice Bran Oil Production Process: Step-by-Step Guide
The production involves several key steps. First, the bran gets separated from the grain. Next, it undergoes a process to extract the oil, usually involving solvents or pressing. The crude oil then gets refined to remove impurities, resulting in clear, healthy oil ready for use.
Oil Extraction: Rice Bran Oil is first extracted from the bran and germ. Oil Refining: The oil is then refined. Separation: The refined oil is separated into a clear liquid and hard fraction. In a more detailed process, the stages include transportation of the raw rice bran to the factory, crude oil extraction, oil refining, and oil storage.
Oil from Rice Bran and its Processing Technology
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‰~3‰ phosphoric acid and a proper amount of water to treat the crude rice bran oil at 90 °C for degumming.
1. Introduction. 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).
A short review of green extraction technologies for rice bran oil
Rice is one of the most important crops throughout the world, as it contributes toward satisfying the food demand of much of the global population. It is well known that rice production generates a considerable number of by-products, among which rice bran deserves particular attention. This by-product is exceptionally rich in nutrients, since it contains a wide spectrum of macronutrients
The steps that occur in a typical rice bran oil refining process, along with the by-products generated are given in Fig. 14.1. Generally, the first step in the refining process with crude rice bran oil is dewaxing or winterizing, although for other vegetable oils the dewaxing step can be done at different times in the refining process.
Processing Technology of Rice Bran Oil
The major prerequisite for processing the oil through physical refining is to have phosphorus content < 5 ppm for degummed, bleached, and dewaxed oil. Degumming is the key pretreatment process before physical refining, followed by bleaching and dewaxing. Because RBO is a dark-colored oil having waxes, special strategies are to be adopted even
Alkali refining – before alkali refining, measure the acid value of crude rice bran oil and calculate the amount of alkali added according to the following formula: Dosage of solid alkali (kg) = quality of rice bran oil (t) X acid value X 0.713
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.
1. Degumming: In this process, phospholipids are eliminated from the crude rice bran oil1. This can be achieved through Acid DE-Gumming or Enzymatic DE-Gumming. 2. Pre-Bleaching: The degummed rice-bran oil is heated and then a pre-calculated amount of bleaching earth is added. This mixture is then transferred to the bleacher.
- How is rice bran oil refined?
- After the extraction, the crude rice bran oil is often refined in order to improve its quality and commercial value. The fundamental steps of the refining process include dewaxing, degumming, neutralization of the free fatty acids, bleaching, and steam deodorization.
- What are the technologies of rice bran oil?
- After that, the fatty acid composition, bioactive compounds, and the processing technologies of rice bran oil are described and the refining technology of rice bran oil (degumming, deacidification, dewaxing, etc.) as well as the technologies to remaining the bioactive compounds in rice bran oil are introduced.
- What are the steps in a rice bran oil refining process?
- The steps in the process of refining rice bran oil are given in Fig. 14.1. The first step in the refining process with crude rice bran oil is usually dewaxing or winterizing. However, for other vegetable oils, the dewaxing step can be done at different times in the refining process.
- What is deacidification of rice bran oil?
- Deacidification is the process of removing free fatty acids from crude rice bran oil. The deacidification methods of rice bran oil include alkali refining, distillation, mixing, re-esterification, and extraction. The alkali refining method has comprehensive effects such as deacidification and decolorization, but the refining loss is much higher.
