Abstract
The carbohydrate composition of the beet pulp [the residues of sugar beet (Beta vulgaris L.) extracts] was compared among three varieties, Monowhite, Hokkai 57 and Sugarman gold. Sugar composition analysis and sugar-linkage composition analysis showed that the carbohydrates in their alcohol-insoluble materials have features in common. However, total phenolic acid content was found to be different among them. In addition, the conditions for saccharification of beet pulp by commercial enzyme preparations were investigated using 16 kinds of crude enzyme preparations. Upon enzymatic saccharification of beet pulp, the 0.1 M NaOH pretreatment is very effective to increase the amount of monosaccharides.
