Features

  •   Compared with starch, it has better fluidity and compressibility. It can be used as a tablet binder by dry or direct pressing process.
  •   Part of the Pregelatinized starch is used in oral hard capsule dry powder preparation. Water content below 7% is specially used as a thinner in capsule prescriptions.
  •   Strong water absorption, in the dry process of granulation, direct tablet, capsule loading reflects: faster disintegration.
  •   The higher the gelatinization degree, the greater the hardness is reflected in the dry granulation and direct pressing.
  •   In the preparation of capsules, it can be used as a filler, thus reducing the difference in the filling process.
  •   In traditional solid preparation, starch pulp can be used as binder and disintegrator instead of original starch. The temperature of pure water in the preparation process will affect the adhesion and disintegrability of pre-gummed starch.
