The other factors affecting starch liquefaction include the source and concentration of the starch; the source and activity of the α-amylase; the concentration of calcium ions, which are related to the activation and stability of α-amylase; and other reaction conditions, such as temperature and pH (Ariff et al., 1997, Baruque et al., 2000, Khedher et al., 2008, Presecki et al., 2013).

Only allowing smaller molecules to pass through it. After 30 minutes, or until you see a distinct color change in the bag or beaker, observe the solution inside the membrane and the solution in the beaker. Which substances are more or less concentrated depends on which one has the most stuff in it. In which direction will water flow initially?
