Descripción del producto

Heat-Stable Alpha-Amylase (HA***0)
Use of HA***0 can bring the following benefits for ethanol prodution:
1.High stability with low pH;
2.Decrease viscosity quickly;
3.Decrease formation of non-fermenting sugars;
4.No need of calcium ion under majority processing conditions;
5.Effective liquefaction of different starch materials, such as tapioca, corn, wheat and rice.

DESCRIPTION
HA***0 is derived from a strain of Bacillus licheniformis using submerged fermentation and refining extraction techniques. Boli HA***0 is an endoamylase, which rapidly decreases the viscosity of a gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D*1, 4 glucosidic bonds to produce soluble dextrins and oligosaccharides.

HA***0 is a robust alpha-amylase suitabel for ethanol industry.

PRODUCT CHARACTERISTICS:

Declared Enzyme	Alpha-Amylase
Systematic Name	1, *-α -D-glucan glucanohydrolase
Activity	0, *0 U/ml (minimum)
Appearance	Light to dark brown liquid
Product pH	5.5 to 7.0
Specific gravity	1.5 to 1.5 g/ml

EFFECT OF PH
HA***0 is active over a wide pH range, depending on the application. For maximum activity, the optimal pH for Boli HA***0 is 5.6 to 6.2. The exact pH optimum will depend on many process variables, including temperature, substrate concentration, and time.

EFFECT OF TEMPERATURE
For interval liquefaction, the optimum temperature of HA***0 is above *5ºC. It liquefies starch substrates promptly at *5 to *7ºC and maintains highly active at **0ºC. For consecutive liquefaction,HA***0 demonstrates exceptional thermo-stability at temperatures up to **5 to **0ºC, maintains its stability for 5 to 7 minutes and keeps on liquefying rapidly and completely.

CONCENTRATION OF CALCIUM
The presence of calcium increases the thermal stability of HA***0. This enzyme requires a very low calcium concentration and calcium additions of *0 to *0 ppm (dry solids basis) are sufficient to ensure enzyme stability.

INHIBITORS
Copper, titanium, and cobalt ions are moderate inhibitors for HA***0. Aluminum, lead and zinc ions act as strong inhibitors.

USAGE GUIDELINES
In general, first adjust the pH to 5.6 to 6.2 and then adding HA***0. Calcium is not needed. After the enzyme is added, heat the slurry to liquefy at the temperature of *5 to *0ºC for *0 to **0 minutes. The final DE value should be maintained at *0 to *2.

Dosage of HA***0 is dependent on the application, substrate concentration, pH, temperature and other processing conditions. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product. A good starting point for dosage rate is 0.*3 to 0.*4 kg/TDS.

PACKAGING
HA***0 is packaged in *0 kg or ***0 kg plastic drums. Customized packaging is available upon request.

STORAGE
Boli HA***0 should be stored below *5° C in its original packaging, sealed and unopened, protected from the sun. This enzyme has been formulated for optimal stability. However, enzymes gradually lose activity over time. Extended storage and/or adverse conditions such as higher temperature may lead to a higher dosage requirement.

SAFETY & ENZYME HANDLING
Inhalation of enzyme dust and mists should be avoided. In case of contact with the skin or eyes, promptly rinse with water for at least *5 minutes. For detailed handling information, please refer to the appropriate Material Safety Data Sheet.
