Amylase Baking enzyme
Whatsapp Order
Amylase Baking enzyme is a class of enzymes that catalyzes the hydrolysis of starch into sugars such as maltose and glucose. In the baking industry, amylases are widely used to improve dough handling, enhance fermentation, increase loaf volume, improve crumb softness, and extend shelf life. The enzyme is typically derived from microbial (fungal or bacterial) sources like Aspergillus oryzae or Bacillus subtilis. Commercial baking amylase products may include α-amylase, β-amylase, and glucoamylase, depending on application needs.
