  • This form of amylase is also called "ptyalin" /ˈtaɪəlɪn/ It will break large, insoluble starch molecules into soluble starches (amylodextrin, erythrodextrin, and achrodextrin) producing successively smaller starches and ultimately maltose. (wikipedia.org)

  • Alpha-amylase (α-amylase) which also has alternate names of 1,4-α-D-glucan glucanohydrolase and glycogenase, is a digestive enzyme which is responsible for breaking down starch to maltose, this can be carried out by hydrolysing alpha-1,4 bonds of large polysaccharides such as starch and glycogen and yielding smaller by-products such as glucose and maltose. (elisakits.co.uk)
  • Whether the end-product is high fructose syrup, dextrose, maltose, maltodextrin or polyols, the process starts with an alpha-amylase for starch liquefaction that can be applied under a wide range of conditions. (in.net)
