We previously reported a new way of producing isomalto-oligosaccharide syrup from starch by using the transglycosylation reaction of neopullulanase (Kuriki, T., Yanase, M., Takata, H., Takesada, Y., Imanaka, T., and Okada, S., Appl. Environ. Microbiol., 59,953-959,1993). The syrup contained isomaltose, a mixture of isopanose and panose, and 6^2-O-α-maltosyl-maltose as isomalto-oligosaccharides with degrees of polymerization (DP) of 2,3,and 4,respectively. Isomalto-oligosaccharides with DP ≧5 were simultaneously obtained by the system, and the structures were analyzed. The results indicated that most of the isomalto-oligosac-charides with DP ≧5 contained two or three α-(1→6)-glucosidic linkages with α-(1→4)-glucosidic linkages. It was also proved that these highly branced oligosacchardies were not limit dextrains from the degration of starch, but were synthesized by the transglycosylation reaction of neupullulanase.
