Abstract: The present invention provides a process for preparing non-cariogenic, sustained energy release juice. The process comprises contacting juice with an enzyme immobilized on Duolite at 30-50° C. for 1-5 h; wherein the enzyme is capable of converting cariogenic sugar to non-cariogenic sugar; and separating juice from the enzyme complex.
