Alpha-Amylase BAA-0800 

DESCRIPTION

BAA-0080 is a food-grade alpha-amylase produced from submerged culture of Bacillus subtilis through extraction and refining processes. It is an endoamylase which can rapidly decrease viscosity of gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the α-1, 4 glycosidic bonds and produce soluble dextrin and oligosaccharide. Prolonged hydrolysis may result in a small quantity of glucose and maltose.

EFFECT OF PH

BAA-0080 remains stable at pH range 6.0 to 7.0. Its optimum pH ranges 6.0 to 6.5. It is inactivated dramatically at pH below 5.0.

EFFECT OF TEMPERATURE

BAA-0080 remains stable at temperatures below 60°C (140°F). The optimum temperature ranges from 60 to 70°C (140 ～ 158°F). At a temperature range from 70 to 90°C (158～194°F), the reaction speeds up with the temperature rises whilst the inactivation also speeds up.

EFFECT OF CALCIUM

The existence of calcium ions plays a protective role for the stability of enzyme activity. The enzyme activity may disappear completely if without calcium ion. The pH range of enzyme activity is broadened with the presence of calcium ions and narrowed without calcium. The concentration requirement of calcium ions shall be 150ppm.

INHIBITORS

Copper, titanium and cobalt ions are moderate inhibitors on this product. Aluminum, lead and zinc ions are strong inhibitors.

USAGE GUIDELINES

[As Dough Improver]

Bacteria alpha-amylase has the ability of anti-staling for bread. Use of BAA-0080 can considerably prolong shelf-life of bread and steamed buns. Recommended dosage rate for trial purpose shall be 0.0125～0.025kg per ton of materials.

[For Fruit Juice Processing]

Use of BAA-0080 can improve the clarity of juice and prevent the formation of haze in the finished products. Recommended dosage rate shall be 0.005～0.025kg per ton of fruit pulps, keeping reaction at 45℃(113°F) for around 60～120 minutes. This product is typically used in combination with pectinase, cellulase and protease to achieve more desirable effects.

[For Brewing]

First, mill the materials to pass through a 40 mesh sieve first, make slurry, then add BAA-0080 into the gelatinization tank at a recommended dosage rate of 1.5kg per ton of raw materials, then liquefy at 85～90ºC for about 30 minutes.

[For Other Application]

In general, the dosage level should be around 0.5～1kg per ton of materials on dry solid basis, concentration of calcium ions should be 150ppm.

PACKAGING

BAA-0080 is packaged in 25kg cardboard drums or kraft paper bags. Customized packaging is available upon request.

STORAGE

BAA-0080 has been formulated for optimal stability. Typical shelf-life is six months provided being stored below 25°C (77°F) 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(32～50°F).

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.
