Rice fiber is plant fiber naturally derived from rice hulls, the outer layer of the rice grain. It is composed primarily of dietary fiber, typically boasting a high fiber content (around 97%), and contains a matrix of both soluble and insoluble fiber components along with lignin.
Key Characteristics of Rice Fiber:
- Source: Rice hulls, a byproduct of rice milling.
- Composition: Primarily dietary fiber (both soluble and insoluble) and lignin.
- Fiber Content: Typically around 97% fiber.
- Functionality: Used as a functional food ingredient to increase fiber content, improve texture, and enhance the nutritional profile of various products.
- Examples: VITACEL® Rice Fiber is a commercially available example.
Benefits and Applications:
Rice fiber is used as a functional food ingredient due to its various benefits:
- Improved Digestion: The high fiber content promotes healthy digestion and regularity.
- Enhanced Texture: It can improve the texture and mouthfeel of food products.
- Nutritional Enhancement: It increases the overall fiber content of foods, contributing to a healthier diet.
- Applications: It's found in a variety of food products, including baked goods, cereals, snacks, and processed foods.
In summary, rice fiber is a concentrated source of dietary fiber derived from rice hulls, used to enhance the nutritional and functional properties of food products.
