Method of purifying sugar juice prepared by extraction of a sugar beet material

摘要

Method of purifying sugar juice which has been prepared by extraction of a sugar beet material comprising mechanically separating undissolved components, chemically treating the juice to convert low molecular non-sugars into higher molecular compounds and to convert non-soluble compounds into soluble compounds and ultrafiltering the sugar juice thus obtained to separate high molecular components therefrom, thus obtaining a purified sugar juice which is suitable for the manufacture of crystalline sugar of a higher quality than conventionally purified sugar juice.
