DESCRIPTION

• TH-18 is a high concentration Heat-stable Alpha-Amylase 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 produces soluble dextrins and oligosaccharides under high temperature and low pH conditions.

PRODUCT BENEFITS FOR TEXTILE INDUSTRY

• TH-18 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
• As a high concentration product, TH-18 can be used after dilution.

EFFECT OF TEMPERATURE AND PH ON ACTIVITY

• Optimum temperature of TH-18 for interval liquefaction is above 77ºC. It liquefies starch substrates promptly at 83 to 90ºC and demonstrates exceptional thermal stability at 100 ºC.
• The exact temperature optimum depends on actual processing conditions, such as pH, concentration of substrate and time.
• The optimal pH is 5.4 to 6.4.
• TH-18 is active over a wide pH range, depending on the application conditions.

INHIBITORS

• Moderate inhibitors for TH-18: Copper, titanium, and cobalt ions 
• Strong inhibitors for TH-18: Aluminum, lead and zinc ions
