Book Description
Cyclodextrins are galnlng industrial interest owing to their particu lar structure. These cyclic amyloses are commonly composed of 6, 7 or 8 (named a-, 8-, y-CD) glucose units. They undergo complexation with quite a large number of substances by molecular inclusion. Their potential for in dustrial application is substantiated by their ability to protect fragile substances from oxygen and UV, to delay the evolution of volatiles and to aid the ancillary processing of dangerous or volatile substances in powder ed form. Though a-, 8- and y-CD exhibit different inclusion specificity, 8-CD has found more attention than the others. This is due to the fact that most of the cyclodextrin producing enzymes known produce predominantly 8-CD. Fur thermore 8-CD is by far the least soluble form, leading to a relatively sim ple production and purification. Consequently 8-CD is already in production on an industrial scale [~] while a- and 8-CD are still more or less re garded as specialities. A further CD-producing enzyme has been found in the medium of K. pneu moniae [l], Since this CGT appeared to produce predominantly a-CD [~], it has been chosen to develop a process for the production of a-CD. MATERIALS AND METHODS Analysis of cyclodextrins: HPLC on Lichrosorb-NH . 10 ~m, with acetonitrile 2 water 65/35 per volume. Test for CGT activity: as described by Landert elsewhere in this Volume. Starch: potato starch as obtained from Blattmann, Wadenswil, Switzerland.

Book Description
This volume contains the proceedings of the Eighth International Symposium on Cyclodextrins, held in Budapest, Hungary, March 31-April 2, 1996. The 147 papers collected here are milestones in the exponentially increasing cyclodextrin literature, and represent a summary of the last two years' achievement in this field, with applications in such diverse disciplines as pharmaceuticals, food, cosmetics, textiles, plastics, and chromatography. Some highlights: lipophilicity profiles of cyclodextrins by computer molecular graphics; recent toxicological studies on cyclodextrins; Buckminsterfullerene/cyclodextrin complexes; hydroxypropyl-beta-cyclodextrin; pharmacokinetics and toxicology; peracylated cyclodextrins as drug carriers; cyclodextrins in nasal drug delivery; textile fibre surface modification by a reactive cyclodextrin; cyclodextrin-containing fabric care products; drug targeting by cyclodextrin-dimers for photodynamic cancer therapy; cyclodextrins in ophthalmologic drugs; new cyclodextrin derivatives and their potentials. Audience: This book will be of interest to researchers whose work involves pharmaceuticals, food chemicals and flavours, food additives, chromatographic methods, and biotechnology, as well as fundamental cyclodextrin research.
