ABSTRACT:
A continuous process for separating components of flaxseed is described. Flaxseed is dried to a moisture content of from about 0.5% to about 3.0%, after which is introduced into a separation chamber having an abrasive rotator therein. As the flaxseed passes over the abrasive rotator, contact with rotator separates the flaxseed components into hulls and kernels. Hulls and kernels are separated and may be used in this form or processed further. Hulls may be further processed by extraction with water and with hexane to remove flaxseed gum and oil, respectively. These two extractions may be done in any order. The process results in a lignan-rich component of flaxseed, a gum extract and oil. These separate components of flaxseed may be used in products such as feed, personal care products or nutraceuticals.
