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.
A process for the production of a high purity d-mannose product from fermented palm oil kernel meal using simulated moving bed separation, said process comprising:
A process for the production of a high purity d-mannose product from fermented palm oil kernel meal using simulated moving bed separation, said process comprising:
A simulated moving bed separation process for the production of a high purity d-mannose extract stream from fermented palm oil kernel meal using simulated moving bed separation, said process comprising passing a palm kernel meal stream comprising water, d-mannose, d-glucose, other sugars, color agents, biomass and salts at a pH of between about 5 and 7 to a simulated moving bed (SMB) zone to provide a highly pure mannose stream comprising d-mannose, color agents, salts, biomass, and water and a primary raffinate stream comprising water, d-glucose, salts, and other sugars, and a secondary raffinate stream consisting essentially of water, said SMB zone comprising a plurality of adsorption beds containing a stationary phase agent comprising a strong acid cation exchange resin in which exchange sites are Ca2+, and introducing a mobile phase stream containing water to said SMB zone, said SMB zone being operated at effective conditions to provide a continuous process for producing the highly pure mannose stream comprising greater than about 95 wt-% d-mannose based on the total sugar in the highly pure mannose stream and returning at least a portion of the secondary raffinate stream to the SMB zone to be admixed with the mobile phase stream, and subsequently removing the biomass from the highly pure mannose stream.
