Embodiment 1

[0030] A preparation process of a crystalline composition containing D-psicose, comprising the following steps:

[0031] (1) Take fructose syrup, dilute it to a sugar concentration of 32.5%, adjust the pH to 6.5, add D-psicose epimerase, and catalyze the reaction at 55°C for 16 hours to obtain D-allulose Compounds of ketose, glucose, and fructose;

[0032] (2) Decolorization: add the compound in step (1) to activated carbon in a ratio of 1% by mass, and stir at 80° C. for 30 minutes;

[0033] (3) Isolation: the decolorized complex in step (2) is passed through a continuous ion exchange system at 40°C at a flow rate of 3 times the resin volume / hour for desalination;

[0034] (4) Concentration: the complex after step (3) is separated and handed over is adopted a four-effect falling film evaporator, the vacuum is 0.08MPa, the temperature of the complex is 80°C, and concentrated to a solid content of 80%, to obtain a complex sugar solution ;

[0035] (5) Crystallization: Contro...

Abstract

The invention relates to a preparation process of a crystalline composition containing D-psicose. According to the preparation method, high fructose corn syrup is taken as a raw material, D-psicose epimerase is added for a reaction, a compound sugar solution containing D-psicose, glucose and fructose is directly prepared, crystallization precipitation is carried out at the temperature of 30-40 DEGC, and the crystal composition containing D-psicose is prepared. The preparation process is simple, the raw material cost is low, the prepared crystalline composition is good in crystalline state, the grain size of crystals is stabilized at 40-60 meshes, the effect of the product can be greatly improved, the sweetness is soft, the calorie is low, and a certain health-care function is achieved while the requirement of people for sweetness is met.

Description

technical field [0001] The invention relates to a preparation process of a crystalline composition containing D-psicose, belonging to the technical field of functional sugar preparation. Background technique [0002] Sugar is mainly used to increase the sweetness of the product. It is one of the traditional sweeteners. It is mainly added to various foods, beverages, bakery products and food processing to improve the taste of food and increase the overall value of food. . [0003] In recent years, due to the exacerbation of obesity and diabetes, some sugars that cause blood sugar rise have gradually attracted people's attention, and it is necessary to develop alternative sugars. [0004] As an alternative sugar, D-psicose can protect nerves by increasing the level of glutathione in cells, and has the functions of lowering blood sugar, reducing fat, improving product quality, and high antioxidant function; as a sweetener Flavoring agent, the sweetness of D-psicose is equival...
