Fungal α-amylase is produced by submerged fermentation of Aspergillus Oryzae followed by purification and formulation. The product depolymerizes starch to produce
oligosaccharides and a small amount of dextrin. The product performs well in
flour mills and bakeries.
MECHANISM
Fungal α-amylase is an endo type of α-amylase that hydrolyzes the α-1,4-glucosidic linkages of damaged
or gelatinized starch and soluble dextrin randomly, giving rise to maltose,
maltotriose, other oligosaccharides and a small amount of dextrin which is
beneficial for flour correction, yeast growth and crumb structure as well as
volume of baked products.
