What Is Rice Bran? What Is It Used For?

Rice bran, a byproduct of rice milling, is a highly nutritious and versatile component gaining recognition worldwide. Derived from the outer layer of the rice grain, rice bran is packed with essential nutrients, antioxidants, and beneficial compounds. Its uses span from health supplements and cooking ingredients to cosmetics and animal feed. This article explores what rice bran is, its composition, and its diverse applications across industries.

Understanding Rice Bran

Rice bran is the hard outer layer of the rice kernel, removed during the milling process that converts brown rice to white rice. While white rice is the polished inner grain, rice bran contains much of the grain’s fiber, vitamins, minerals, and healthy oils.

• Antioxidants: Such as tocopherols and tocotrienols (forms of vitamin E), and oryzanol.

• Protein: Provides plant-based protein content.

Nutritional Benefits of Rice Bran

Rice bran is considered a superfood due to its dense nutritional profile:

• Heart Health: The oil contains compounds that may help lower cholesterol and improve cardiovascular health.
