Description

technical field

[0001] The invention relates to the field of functional sugar production, in particular to a device and method for suppressing turbidity of liquid maltitol. Background technique

[0002] Maltitol is a new type of functional sweetener, because of its low-calorie, non-carious, indigestible, calcium absorption promotion and other physiological properties, it has attracted widespread attention and is widely used in food industry. Maltitol is a white crystalline powder or a colorless transparent neutral viscous liquid, and the latter is the liquid maltitol mentioned in the present invention, which is obtained from starch through pulping, liquefaction, saccharification, hydrogenation, purification and separation, and concentration . Since the nitrogen-containing substances in starch cannot be completely removed during the purification and separation process, and the liquefaction and saccharification processes cannot fully enzymatically hydrolyze the starch, leavi...
