Embodiment 1

[0014] 1) Add activated carbon to the isomalt solution with a mass concentration of 40% according to 2% of the dry matter of isomalt, raise the temperature to 80°C and keep it for 30 minutes, and use D301 anion resin and 001* after suction filtration 7 cationic resins were ion-exchanged to obtain a 97% isomalt solution with a purity of 98% and light transmission.

[0015] 2) Concentrate the ion-exchanged isomalt solution through a rotary evaporator to a mass concentration of 60%; then granulate the concentrated isomalt solution with a spray drying tower, and control the air inlet temperature at 130°C to control peristalsis Pump feed rate 0.5L / min.

[0016] 3) Sieve the above-obtained isomaltulose granules to obtain granular isomaltulose, with a purity of 97.69% as detected by liquid chromatography.

Embodiment 2

[0018] 1) Add activated carbon to the isomalt solution with a mass concentration of 45% according to 5% of the dry matter of isomalt, raise the temperature to 75°C and keep it warm for 30 minutes, and use D301 anion resin and 001 after suction filtration *7 The cation resin is ion-exchanged to obtain a 98% isomalt solution with a purity of 99% and light transmission.

[0019] 2) The ion-exchanged isomalt solution is concentrated by a rotary evaporator to a mass concentration of 40%; then the concentrated isomalt solution is granulated with a spray drying tower, and the air inlet temperature is controlled at 170°C to control peristalsis Pump feed rate 1.5L / min.

[0020] 3) Sieve the above-obtained isomaltulose granules to obtain granular isomaltulose, with a liquid phase detection purity of 98.56%.

Embodiment 3

[0022] 1) To the isomalt solution with a mass concentration of 42%, add activated carbon according to 3% of the dry matter of isomalt, raise the temperature to 75°C and keep it warm for 30 minutes, and use D301 anion resin and 001 after suction filtration *7 The cation resin is ion-exchanged to obtain a 99% isomalt solution with a purity of 98% and light transmission.

[0023] 2) The ion-exchanged isomalt solution is concentrated by a rotary evaporator to a mass concentration of 50%; then the concentrated isomalt solution is granulated with a spray drying tower, and the air inlet temperature is controlled at 160°C to control peristalsis Pump feed rate 1.0L / min.

[0024] 3) Sieve the above obtained isomaltulose granules to obtain granular isomaltulose alcohol, and the purity of liquid phase detection is 99.17%

Abstract

The invention discloses an isomalt granulation process. By using an isomalt solution as a raw material, isomalt powder is directly obtained by using a spray drying method. On the premise of producing isomalt meeting requirements, compared with existing preparation methods such as a negative-pressure crystallization method and a melt crystallization method, the isomalt granulation process has the advantages of simple process, short consumption time, low labor intensity and the like.

Description

technical field [0001] The invention belongs to the field of functional sugar production, and in particular relates to a granulation process of isomalt. Background technique [0002] Isomalt is a kind of mixture, called isomalt in foreign countries, it is an emerging functional edible sugar alcohol in the world in recent years, and it is an ideal sugar substitute. Its unique physical and chemical properties, physiological functions and food safety have been fully confirmed by experiments. It has been given the highest level of food safety "GRAS (Generally Recognized as Safe)" by the US FDA, and its daily intake is not limited. Its consumption has risen sharply in recent years. In developed countries such as Europe and the United States, it has occupied more than 50% of the market of sweeteners used in sugar-free foods. Tabletop sweeteners and more. [0003] Isomalt is composed of α-D-glucofuranosyl-1,6-D-sorbitol GPS and α-D-glucofuranosyl-1,1-D-mannitol GPM at a ratio of ...
