Rice hull concentrate

Rice bran extract is described as a skin-conditioning agent and is comprised of carbohydrates, proteins, lipids, mineral ash and water 1. Concentrations are normally in the 1%-2% range. Other components include tocopherols 1. Physical processes: Hypothermal processing of rice hulls will concentrate the fiber (extracting alkaline, moderate temperatures) followed by neutralization with an organic acid; this process concentrates and decolorizes dietary fiber to remove unwanted materials and enhance its functionality 2. Rice hull concentrate also helps flow.
