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.
