How is glucose syrup produced from starch using starch hydrolysing enzymes

2018-03-23 /

At present, with the starch syrup produce technology develop, we have many different way to produce glucose syrup from starch like acid using, enzyme process and multi-enzyme using. But the acid way with many limits of starch quality and requests the syrup equipment have high corrosion resistance, and acid method for starch syrup produce capacity is less extracting rate than uses enzymes. So adopts enzymes and multi-enzymes to produce glucose syrup from starch is a better choice.

How is glucose syrup produced from starch using starch hydrolysing enzymes

First, starch hydrolysing enzymes is an enzymes which is only used for starch, can hydrolyze the starch into polysaccharides, high efficiency and specificity. The hydrolysing enzymes divided into α-enzyme and β-enzyme, the α -enzyme applied to starch, it have strong hear-resistence, when temperature rised to 93-95℃ still keep activited. After α-enzyme using, fastly decrease the viscosity of starch, changed it to liquefied starch, so α-enzyme also named starch hydrolysing enzyme. Commonly applied to glucose syrup liquefication process. Following picture show you the enzymes uses area of glucose syrup produce:

How is glucose syrup produced from starch using starch hydrolysing enzymes

Using starch hydrolysing enzymes to produce glucose syrup from starch have two steps:

Step one: Add starch hydrolysing enzyme that is α-enzyme changed starch to dextrin or oligose, increased the solubility of starch, this process named liquefication.

Step two: Use saccharifying enzyme make the oligose or dextrin further hydrolysing, changed the liquid to glucose syrup, this process called saccharification.

Glucose syrup produced equipments

Liquefication and saccharification process all ued enzymes to produce. These two produce process is the basics of glucose syrup produce, further high fructose syrup produce, in the following process, aslo need enzymes to make isomerism process, change the 42% contain glucose to fructose can get F42 high fructose syrup. That's all, this is the full introduce of glucose syrup produced from starch using starch hydrolysing enzymes.
