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 sa

Embodiment 1

[0026] Adjust the Baume degree of starch slurry to 14, pH value to 5.6, add Liquozyme Supra0.12 Kg / t (干淀粉) , stir well.

[0027] After the first American automatic control of water heater jet liquefaction, the temperature is 105°C and the flow rate is 17m 3 / h. After cooling to 94°C and holding the heat for 120 minutes, the second American automatic control water heater sprays, the temperature is 125°C, and the flow rate is 17m 3 / h.

[0028] Cool to 59°C, automatically adjust the pH value to 4.8, add β-amylase NOKEZYM SBA 1.13 Kg / t to the automatic enzyme adding system (干淀粉) , Promozyme D2 1.27 Kg / t (干淀粉) . After 15 hours, add Maltogenase L 0.14 Kg / t (干淀粉) . The saccharification reaction lasted for 40 hours. At this time, the maltose content of the saccharification liquid was 90.01% ultra-high maltose syrup.

Embodiment 2

[0030] Adjust the Baume degree of starch slurry to 17, pH value to 5.8, add Liquozyme Supra 0.14 Kg / t (干淀粉) , stir well.

[0031] After the first American automatic control water heater jet liquefaction, the temperature is 109 ℃, the flow rate is 20m 3 / h. After cooling to 98°C and holding for 90 minutes, the second American automatic control water heater sprays, the temperature is 140°C, and the flow rate is 20m 3 / h.

[0032] Cool to 63°C, automatically adjust the pH value to 5.6, add β-amylase NOKEZYM SBA 1.32 Kg / t to the automatic enzyme adding system (干淀粉) , Promozyme D2 1.0 Kg / t (干淀粉) . After 15 hours, add Maltogenase L 0.19 Kg / t (干淀粉) . The saccharification reaction lasted for 60 hours. At this time, the maltose content of the saccharification liquid was 92.28% ultra-high maltose syrup.

Embodiment 3

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...
