application:
1). in pharmaceutical field, alpha-cyclodextrin and medicine could produce inclusion compound, which could: a. make unstable medicine stable; b. make deliquescing,
sticky and liquid medicine more powder-like; c. make insoluble or hard-soluble
medicine soluble.
2). in pesticide field, alpha-cyclodextrin and medicine could produce inclusion compound
to make some pesticides store and increase insecticidal efficacy.
3). in food field, alpha-cyclodextrin could: a. cover and remove peculiar smell;
b. improve and enhance food organization structure; c. relieve and remove bitter and
astringent; d. anti-oxidation; e. keep and improve relish.
4). in daily chemical field, alpha-cyclodextrin could function as emulgator and quality
improver in cosmetics production. it could also be applied in tooth paste and tooth powder
as deodorant and preservative.
5). in environment-protection field, alpha-cyclodextrin could be applied as treatment of
waste water with oil. alpha-cyclodextrin water solution could be used to clean oil groove
and recycle it to get fuel oil.
6). in chemical field, fluorescence intensity of fluorchrome is enlarged remarkably with
alpha-cyclodextrin, so it could be used to analyze protein and amino acid. it could also
be used to separate long-chain organic compounds, raceme etc. besides, absorbent
made from alpha-cyclodextrin could be used as adsorption of chromatographic analysis.
