Thus, a reducing sugar solution of a high concentration is produced. In the meantime, the bio-substance containing lignocellulose does not need a high-temperatured steaming after the degradation. Therefore, the water amount and the energy resources that are applied in the present invention are less than those of the conventional technique. Further, the autoclave is a common apparatus in the market, which facilitates in an easy purchase, decreases the producing cost, and benefits the product promotion. | 01-17-2013 |

20140039180 | MANNOSE PRODUCTION FROM PALM KERNEL MEAL USING SIMULATED MOVING BED SEPARATION - 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. | 02-06-2014 |
