Maltose production and refining method

Abstract

The invention belongs to the technical field of functional sugar production, and particularly discloses a maltose production and refining method. The maltose production and refining method uses an automatically controlled water heater to spray and liquefy starch milk for two times, an automatic enzyme-dosing system to carry out a liquefied liquid saccharification process, and membrane filtration in the process of refining obtained crude syrup into maltose syrup in the end, and the obtained maltose syrup is then refined, purified, concentrated, centrifuged and dried, so that high-purity maltose is obtained. According to the invention, the steps are simple, the operation is easy, the production period is short, the automation degree is high, the production cost can be effectively reduced, and the industrialized production of maltose with a content being more than 90 percent can be realized.

Description

(1) Technical field [0001] The invention belongs to the technical field of functional sugar production, in particular to a method for producing and refining maltose. (2) Background technology [0002] The molecular formula of maltose is C 12 h 22 o 11 h 2 O, easily soluble in water, low and mild sweetness, strong palatability and good taste. Maltose has excellent properties such as anti-crystallization, low freezing point, moisture retention, and high boiling temperature. It is used as a thickener, plasticizer, sweetener, anti-browning agent, applications such as preservatives. Because maltose also has the property of low osmotic pressure, it can be absorbed by the human body without the need for pancreatic islets. It is a low-calorie sugar product that can replace glucose for patient infusions. It is not easy to cause blood sugar to rise. It is especially suitable for diabetic patients and during surgery. and postoperative patients. In traditional Chinese medicin...

Problems solved by technology

[0003] In recent years, due to the unique properties of maltose, especially with the wide application of ultra-high maltose, a lot of research has been done on the production process of maltose in China, but because (1) the cooking effect of ordinary domestic injectors is not uniform and thorough, On the one hand, part of the raw starch enters the saccharification process, causing the iodine test to show blue-purple after saccharification, which is unqualified, and the highest maltose content is only 80-85%. It brings great difficulty; (2) The decolorization stability of activated carbon is poor, the product yield is low, and a large amount of waste carbon is discharged at the same time, which increases the operating cost of the enterprise and the difficulty of local environmental protection; (3) The heat transfer of ordinary tube evaporators The coefficient is low, the steam consumption is large, and the heating pipe is prone to dead pipe phenomenon, which not only reduces the heat transfer area, but also easily causes corrosion damage to the heating pipe, increasing the workload of maintenance and cleaning

It is the existence of the above three major shortcomings that make the content of ultra-high maltose low, the production cost high, and it is difficult to realize industrialization, which greatly limits the popularization and use of high-purity maltose
