The Pyongyang Cornstarch Factory has newly established an isomerase production process.
Isomerase plays a big part in changing glucose into isomerized sugar.
“We buckled down to producing enzymes based on locally-available raw and other materials over 10 years ago and ensured the domestic production of several enzymes needed for the production of starch syrup and glucose,” said workshop manager Pak Song Gun.
According to him, sugars treated by such enzymes are well absorbed into human body and helpful to curing diabetes, obesity and gastric disorders and lowering the content of blood sugar, while causing less caries.
This year, the factory set it as a technical innovation task to ensure the domestic production of isomerase playing a pivotal role in producing oktang sugar 1.4 times sweeter than normal sugar, and pushed ahead with it.
In the course of this, researchers succeeded in cultivating excellent isomerase-generating bacteria after finding out technical features of the bacteria, ascertained culture conditions suitable to biochemical requirements of the bacteria and solved some technological problems for ensuring the mass production of isomerase.
They also channelled great efforts into making such facilities as culture tanks and isomerase moulding machine, thus establishing production processes including those for the culture and washing of the bacteria and centrifugation.
“The completion of the industrial production foundation for isomerase, which has remained a knotty problem in producing oktang sugar, made it possible to put an end to the last index of imported goods for the factory,” said manager Pak Hyong Ryol.
