Abstract

The invention relates to a method for purifying tagatose by using sequential simulated moving bed chromatography (SSMB). Pretreated tagatose crude syrup is used as a raw material, an SSMB is utilized to purify the tagatose, deionized water is used as eluting agent, the working temperature of the separating column is 50-70 DEG C, and a calcium-type strongly-acidic cation gel resin is used as a chromatographic stationary phase, thereby obtaining the high-purity tagatose and implementing higher yield. The whole technique has the advantages of low operating cost, low production energy consumption, zero discharge and high degree of automation, and can implement continuous production and enhance production efficiency.

Description

technical field [0001] The invention belongs to the field of food industry, and specifically relates to a sequential simulated mobile chromatography separation and purification technology, in particular to a sequential simulated mobile chromatography purification technology for tagatose. Background technique [0002] Tagatose is a rare natural ketohexose, an isomer of galacturosone, and an epimer of fructose at the C-4 position. Tagatose products have been approved for use by the food hygiene departments of the United States, Australia, Japan, South Korea, and New Zealand, but have not yet been industrialized in my country. Our country has also carried out some research work on tagatose. Chinese patent 200910307138.5 has announced a kind of method for preparing L-tagatose, and what this method has adopted is the method of fermentation; Chinese patent 201080067326.6 has announced a kind of method for preparing tagatose and glucose, and its method is that Hydrolysis to galac...
