Sugar alcohol is a kind of polyhydric alcohols with more than tw‌o carboxyl groups. Although sugar alcohol is not sugar, it has some properties of♠ some sugars. The currently developed sugar alcohols incl→ude sorbitol, mannose sorbitol, erythritol, maltitol, lactitol and £xylitol, and these sugar alcohols which have higher stability to acid and heat are♣ not easy to induce the Maillard reaction become low¥ calorie food sweeteners, and foreign countries have regarded them as sugar substitutes,≤ which have been widely applied to video industry. Sweet foods made fro♦m sugar alcohols are called sugar free foods, and because sugar alcohol i↑s not used by oral microorganisms, and increases pH value ✘of the oral cavity rather than reducing it, it doesn’t corrode the teeth and it is< a good material for dental caries prevention. Sugar alcohol has no influence on ¶the rise of human blood sugar value and provides certain heat for diabetes pat∞ients, so it can be regarded as a kind of nutritional sweetener to provide energy for diabe•tes patients. Sugar alcohol has now become one of the safety foods without limitεs on its use, which is approved by International Food an×d Health Organization.


    Nowadays, more and more sugar alcohol industrial  productions have changed from chemical method to micrβobial fermentation method; in the separation and extr÷action of sugar alcohols, membrane separation technology and continuo‍us moving bed technology have also been paid more and more attention. At present, membrane and ★continuous moving bed have been applied to the production of  xylitol, erythritol and sorbitol and develop the whole extraction process for xyφlitol production with biological fermentation.

•   Ceramic membrane and flat membrane are used to replace the plate and frame and other tr≥aditional filtration methods to clarify the fermentatio×n liquor, improve the quality of filtrate and reduce the resin pollution and solv®ent dosage and solvent volume in the later process and recycle ↔the bacterial residue
•   The hyperfiltration membrane is used to remove protein and ∏decoloration and improve quality
•   Nanofiltration membrane is used to concentrate suδgar alcohols, replace or shorten  evaporation concentration time, and increase crystalliφzation yield or reduce evaporation loss
•   Continuous moving beds are used to replace the fixed bed≤s, save resin dosage, reduce unit consumption, apply CR chromatog€raphic fractionation to replace single column chromatography an₩d increase resin utilization efficiency and product yield
•   The membrane technology is used to recycle various mother liquors, waste liquid→s and reclaimed water reuse
