Natto Powder Local Standard

In July 2019, SungenBio successfully promoted the "Guangdong Province Food Safety Local Standard (Natto Powder)" (DBS 44/013-2019). Nattokinase activity was taken as a main physical and chemical index for testing the qualified standard of Nattokinase powder,and Ultraviolet spectrophotometry and agar-fibrin plate assay were taken as standard methods for accurately measuring nattokinase activity. In the future, SungenBio will continue to promote the development of national standards for natto powder and lead the standardized development of industry.

The Fourth Generation Production Technology(Independent Innovation)
Technology Crafts Ingredient Highest Activity
The First Generation Handcraft Nattokinase, Bacillus natto, Purine 1,000FU/g
The Second Generation Solid Fermentation Nattokinase, Bacillus natto, Purine 3,500FU/g
The Third Generation Liquid Fermentation Nattokinase, Purine 20,000FU/g
The Fourth Generation Deep Liquid Fermentation, Membrane Integration Highly Active Nattokinase 750,000FU/g
Nattokinase Activity Assay

High Performance Liquid Chromatography(HPLC)

Nattokinase activity was determined by HPLC.It not only can quickly detect nattokinase content, but also provide a quantitative method for the study of nattokinase drug properties.


Nattokinase pure products (Activity 750,000FU/g ) were purified by protein purification process. Nattokinase activity unit was defined as NKIU by SungenBio.

Tasteless Nattokinase

Upgrade the process to remove the special smell of natto.
