BAA-240 is a food-grade alpha-amylase produced from classical strains of Bacillus subtilis through submerged fermentation , 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 produce glucose and maltose.

*Colour may vary from batch to batch. Colour intensity is not an indication of enzyme activity.
Effect of pH
BAA-240 is stable at pH ranges 6.0 to 7.0. Its optimum pH range is 6.0 to 6.5. BAA-240 can be inactivated dramatically at pH below 5.0.
Effect of Temperature
Effective temperature for BAA-240 is 30 to 90°C; Optimum temperature range is 60 to 90°C. At a temperature range of 70 to 90°C, the reaction is accelerated with the temperature rises whereas the enzyme inactivation also speeds up.
To brew beer with rice or corn as auxiliary materials, first grind the raw materials through a 40-mesh sieve, then pulp, adjust the pH value of 6.2-6.4, add 0.2% calcium chloride (according to raw materials), then add BAA-240 at the amount of 2-3 kg per ton of auxiliary materials, heat the slurry to 85 ℃ and 90 ℃ for about 30 minutes.
Effect of Calcium
The existence of calcium ions plays a protective role in the stability of enzyme activity.
If there is no calcium ion, the enzyme activity may disappear completely.
The pH range of enzyme activity widened when calcium was added and narrowed when calcium was not added.
The requirement of calcium concentration is 150ppm.
