Abstract
Disclosed is a process for the production of d-mannose from fermented palm oil kernel meal using a continuous SMB separation process. The process is useful for providing a simplified processing route to providing high purity d-mannose. The SMB process and the SMB cycle was operated to provide a high purity mannose stream comprising d-mannose, salts, and color agents, a primary raffinate comprising glucose, other sugars and salts, and a secondary raffinate consisting essentially of the mobile phase desorbent. In the SMB cycle, the secondary raffinate was recycled to the SMB process as the mobile phase desorbent without further desalination. The highly pure mannose stream was further treated to remove color agents and salts prior to subsequent steps of precipitation or crystallization and drying. D-mannose is useful as a food additive, as a sweetener, as a texturizer, as a stabilizer, or as a humectant.
