| Abstract: | This paper studied enzymatic preparation of isomalto-oligosacchrides by using wheat starch as raw material.Liquefied by thermostable α-amylase“SPEZYMEFred”,sacchrified by fungal α-amylase “CLARASEL” and transglucosylated by “Transglucosidase L-500”(all from GENENCOR International Inc.).The optimum conditions were obtained:liquefied to 15-17 DE,sacchrified and transglucosylated at 55℃ for 24 hours,pH 4.5,10 SKBU/g CLARASEL and 1.4 TGU/g Transglucosidase L-500 added.The product contains 23.3% isomaltose,13.9% panose and 10.2% isomaltotriose.Its quality is superior to those in the market. |
