摘要
Digestion of potato starch with His-modified alpha-cyclodextrin glycosyltransferase from Klebsiella pneumoniae M 5 al yielded branched tetra- to nona-saccharides, as revealed by debranching with pullulanase. Maltose and maltotriose stubs preponderated together with small proportions of D-glucose stubs. The branched saccharides accounted for approximately 1.2% of the starch.
