Component Specifications

Definition
Alpha-amylase (EC 3.2.1.1) is an endoamylase enzyme that catalyzes the hydrolysis of internal α-1,4-glycosidic bonds in starch, glycogen, and related polysaccharides, producing maltose, maltotriose, and α-limit dextrins. In industrial applications, it operates optimally at temperatures of 60-90°C and pH 5.5-7.0, sourced from microbial strains like Bacillus licheniformis or Aspergillus oryzae for enhanced thermostability and activity.
Working Principle
Alpha-amylase works by randomly cleaving α-1,4-glycosidic linkages in starch molecules, reducing viscosity and converting long-chain polysaccharides into shorter oligosaccharides, facilitating processes like liquefaction in starch processing or sugar production.
Materials
Typically derived from microbial fermentation (e.g., Bacillus or Aspergillus species), formulated as liquid concentrates or solid powders with stabilizers like calcium ions for activity preservation.
Technical Parameters
  • Activity ≥ 10,000 U/g
  • Optimal pH 5.5-7.0
  • Shelf Life 12-24 months at 4-25°C
  • Particle Size < 100 μm (powder)
  • Optimal Temperature 60-90°C
Standards
ISO 11212, DIN 10342
