When choosing the right cooking oil for your kitchen, it’s important to understand what the oil is made from and how it benefits your health. One popular option that has gained attention in recent years is rice bran oil. But many people still ask, what is rice bran oil made of? The answer is simple: it is extracted from the outer layer of rice grains, known as rice bran. This part of the grain is usually removed during the milling process. Rice bran oil is valued for its high smoke point, light flavor, and health-supporting nutrients.
In this blog, we will explore how rice bran oil is made, what is rice bran oil made of, and why it’s a smart choice for daily cooking.
What Is Rice Bran?
Before understanding what rice bran oil is made of, we need to know what rice bran is. Rice bran is the outer brown layer of the rice grain that is removed during the milling of white rice. This layer includes the pericarp, seed coat, nucellus, and aleurone layers, which are rich in nutrients and oils.
Rice bran, though often considered a byproduct, is packed with healthy fats, antioxidants, vitamins, and minerals. It is from this bran layer that rice bran oil is extracted.

How Is Rice Bran Oil Made?
Now let’s answer the main question: what is rice bran oil made of and how is it produced?
1. Source Material
Rice bran oil is made from rice bran, the hard outer layer of rice grains. This layer is removed during the process of polishing brown rice to make white rice.
2. Oil Extraction
Once the rice bran is collected, it undergoes an oil extraction process. There are two main methods:
- Mechanical Pressing: In this method, rice bran is pressed using machines to extract the oil. This is considered more natural.
- Solvent Extraction: A chemical solvent like hexane is used to pull the oil from the bran. This method is more efficient for large-scale production.
3. Refining
After extraction, the oil is refined to remove impurities, odors, and free fatty acids. The result is a clear, light, and mild-tasting oil suitable for cooking.

2. Gamma-Oryzanol
- A natural antioxidant unique to rice bran oil
- Helps lower cholesterol
- May reduce inflammation and support hormone balance
3. Vitamin E
