| Summary | The brewing thermostable α-Amylase is used for quick adjunct liquefaction to avoid viscosity buildup during gelatinization and to have satisfactory starch conversion and smooth operation. |
| Description |
Thermostable alpha-amylase is produced through the submerged fermentation of Bacillus licheniformis, followed by purification and formulation. This enzyme is particularly useful in brewing for the liquefaction of starch during high-temperature gelatinization processes, addressing viscosity issues effectively. Key Benefits of Thermostable Alpha-Amylase: - Efficient DE Development: Facilitates the breakdown of starch to produce dextrins and oligosaccharides. - Rapid Viscosity Reduction: Quickly reduces the viscosity of starch paste during gelatinization. - Low Color Formation: Minimizes color changes in the final product. - Calcium Requirement: Generally performs well without the need for additional calcium. As a member of the hydrolytic enzyme family, this alpha-amylase targets the α-1,4-glycosidic bonds in starch, producing dextrins, oligosaccharides, and a small amount of glucose. Its excellent thermostability allows it to maintain effectiveness at high temperatures, ensuring efficient viscosity reduction during the brewing process. |
| Advantages |
Fast and consistent liquefaction of brewing adjuncts without viscosity problem No danger of resistant or retrograded starch formation Improved flexibility in using various cereal grain adjuncts |
| Application | For adjunct liquefaction in brewing |
| Application Area | Brewing |
| Application Recommendation | The recommended dosage is 0.2-0.5 L of the enzyme preparation per ton of starch, added at liquefaction. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume. |
