| Abstract: | The concentrations of limonoid glucosides in orange molasses, a byproduct of citrus juice processing, were measured. The 17-β-D-gluco-pyranoside derivatives (glucosides) of limonin, nomilin, nomilinic acid and obacunone were present and quantified. Orange molasses contained an average of 568 ppm of total limonoid glucosides at 11.8°Brix. Orange molasses (3.8L) contained up to 12.5g of total limonoid glucosides. The molasses could be used as a source for commercial isolation of citrus limonoid glucosides. |
