Product Description



Technical Grade Baterial Alpha-Amylase TB-2


Halal & Kosher Certified Desizing Enzyme Adapted to Low Temperature  


No pollution,

No damage to fabrics,

Wash out the starchy materials easily

Cost Effective




Alpha-Amylase TB-2 is a cost-effective desizing alpha-amylase, considerably reduces water consumption and processing costs, nodamage to fibers.

Alpha-Amylase TB-2 is suitable for desizing of textiles sized by starchy materials, particularly fits to those textiles that are not heat resistance, such as cotton, silk, synthetic fabrics. Use of TB-2 enables mild operational conditions, no pollution, no damage to the fabrics, easily to wash out the starchy materials.


Declared Enzyme Alpha-Amylase
Systematic Name EC, alpha -1, 4–glucan 4-glucanohydrolase
Activity 2,000 U/ml (minimum)
Appearance Light to dark brown liquid
Product pH 5.0 to 7.0
Specific gravity ≤1.25 g/ml



Bacterial Alpha-Amylase TB-2 is produced from strains of Bacillus subtilis through submerged fermentation, extraction and refining process. It can rapidly decreases the viscosity of the gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-1, 4 glycosidic bonds and produces soluble dextrins and oligosaccharides.


The powerful amylase activity of TB-2 is capable to break down the starches contained in the textiles into soluble polysaccharides, thus makes it washed out easily.



  • TB-2 is active at pH ranges from 6.0 to 7.0 with an optimum pH at 6.0. It can be inactivated dramatically at pH below 5.0
  • TB-2 is active at temperatures from 30 to 90ºC, with an optimum temperature range from 60 to 90ºC.
  • At temperatures from 70 to 90ºC, the reaction speeds up with the temperature rises while the enzyme  inactivation also speeds up.



  • Copper, titanium and cobalt ions are moderate inhibitors for TB-2
  • Aluminum, lead and zinc ions act as strong inhibitors for TB-2



Calcium ion plays a protective role for the stability of alpha-amylase activity for TB-2. Its activity may disappear completely without the presence of calcium ion.


  • 25kg, 30kg plastic drums or 1125kg IBC totes
  • Customized packaging is also available upon request
Shelf-life and Storage:
  • Typical shelf-life is six months if it is stored below 25°C in its original packaging, sealed and unopened, protected from the sunlight.
  • Its shelf-life will be eighteen-months if this product is being store properly at 0∼10°C.
  • Prolonged storage and/or adverse conditions such as higher temperatures may lead to  higher dosage requirement, thus should be avoided.
