✦ Synopsis

Cyclomalto-oligosaccharides

(cyclodextrins, CDs) with maltosyl and panosyl branches were produced from maltose or panose and CDs by the reverse action of pullulanase.

Purification on columns of octadesylated silica gave maltosylcyclomalto-hexaose and -heptaose and panosylcyclomalto-hexaose and -heptaose. The solubility of maltosylcyclomaltoheptaose in aqueous 80% ethanol was higher than that of cyclomaltoheptaose in water. The relative rates of degradation of maltose, maltosylcyclomaltohexaose, and maltosylcyclomaltoheptaose with glucoamylase were 1:3.6:5.0, and those of panose, panosylcyclomaltohexaose, and panosylcyclomaltoheptaose were 1:3.0:2.2. The rates of degradation of branched and unbranched malto-oligosaccharides were markedly different, as were those of maltosyl-and panosyl-cyclomalto-oligosaccharides.
