Microparticles include a matrix of an encapsulating material, in which are dispersed particles of a low melting point fat and a bioactive material, such as one or more probiotic bacteria. The microparticles are formed by preparing an emulsion of melted low melting point fat in an aqueous mixture of the encapsulating material, cooling the emulsion below the melting point of the low melting point fat, dispersing the bioactive material in the emulsion and spray drying the emulsion. The particles of solid low melting point fat are believed to protect the bioactive material from heat damage during the spray drying process.

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.
