  Description:
  Beta cyclodextrin is a kind of
  oligosaccharides generated from
  starch under the action of
  glucose transfers, with
  particular closed carridge
  molecular structure. It can be
  used as inclusion substance for
  many kinds of materials.
  
  In pharmaceuticals: Beta
  cyclodextrin are not irritant and
  offer distinct advantages, such
  as the stabilisation of active
  compounds. Reduction in
  votatility of the drug molecules,
  and masking of malodours and
  bitter tastes.
  
  Main functions:
  1. Protection of materials
  against oxidation and uv-
  degradation during storage and
  processing.
  2. Masking of bitterness and
  terrible odour of foods and
  drugs.
  3. Stabilization of flavours and
  spices.
  4. Conversion of liquid materials
  into dry form.
  5. Improve of solubility of
  materials with low solubility in
  water.
  6. Emulsification of
  hydrocarbons, steroids, fats and
  fatty acids.
  7. Controlled release of drugs
  and flavours.
  8. Catalyst for chemical
  reactions.
