Abstract: The changes of low molecular weight saccharides in the reaction solution were studied by measuring dextrose equivalent value (DE) and their effect on β-CD production was analyzed. Four kinds of additives including ethanol, dimethyl sulfoxide, acetonitrile and cyclohexane were added individually to explore their effectiveness. The results showed that the accumulation of low molecular weight saccharides could inhibit the synthesis of β-CD. The addition of the additives could reduce the content of low molecular weight saccharides in the reaction system and help to increase β-CD production.

Key words: cyclodextrin, synthesis, conversion rate, dextrose equivalent (DE)
