Powder Heat-stable Alpha-Amylase TH-0400 

Halal and Kosher Certified

BENEFITS
Use of TH-0400 in desizing of textiles can ensure the following benefits:
1) Enable desizing and colour-fixing at the same bath, thus shorten process flow and improve productivity
2) Enhanced capillary tube effect of fabrics
3) Improved working conditions for operators
4) Less dosage level and reduced processing costs

Heat-stable Alpha-Amylase TH-0400 is produced from Bacillus licheniformis through submerged fermentation, extraction and refining process. It is an endoamylase that can efficiently decrease viscosity of gelatinous starch solutions by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1 glycosidic bonds and produce soluble dextrins and oligosaccharides under high temperature and low pH conditions.

TH-0400 has an excellent heat resistance and a wide pH range.

It is suitable for desizing of textile fabrics such as cotton, silk, polyvinyl alcohol fibers, rayon fibers, blended fabrics, dyed poplin, etc.

EFFECT OF TEMPERATURE
Optimum temperature of TH-0400 for interval liquefaction is above 77°C. It liquefies starch substrates promptly at 83 to 90°C and demonstrates exceptional thermal stability at 100 °C. The exact temperature optimum depends on actual processing conditions, such as pH, concentration of substrate and time.  

EFFECT OF PH
TH-0400 is active over a wide pH range, depending on the application conditions. The optimal pH is 5.4 to 6.4.

INHIBITORS
Copper, titanium, and cobalt ions are moderate inhibitors for TH-0400, whereas aluminum, lead and zinc ions act as strong inhibitors.

CONCENTRATION OF CALCIUM
The presence of calcium increases the thermal stability of this enzyme. It requires a very low calcium concentration, i.e. 5 to 20 ppm will be sufficient to ensure its thermal stability.
 

PACKAGING

TH-0400 is packaged in 25kg cardboard drums or kraft paper bags. Customized packaging is available upon request.

STORAGE

TH-0400 has been formulated for optimal stability. Typical shelf-life is six months provided being stored below 25°C in its original packaging, sealed and unopened, protected from the sunlight. Its shelf-life is eighteen months if it is stored 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.

SAFETY & ENZYME HANDLING

Inhalation of enzyme dust and mists should be avoided. In case of contact with skin or eyes, promptly rinse with water for at least 15 minutes.For detailed handling information, please refer to the Safety Data Sheet.
