Dow offers resins designed specifically for beet syrup processing, including de-ashing, de-calcification (softening), decolorization, invert sugar production and chromatographic separation of molasses to recover sucrose, betaine or amino acids.
| Operation | What it Does | Resin(s) Used |
| Softening - conventional process | Removal of calcium prior to evaporation, using NaCl as regenerant | DOWEX™ HCR-S strong acid cation resin or DOWEX MARATHON™ C-10 strong acid cation resin |
| Softening - High-flow process | Removal of calcium prior to evaporation, especially for softening when sucrose will be recovered from molasses by chromatographic separation (molasses de-sugarization; ion exclusion) | DOWEX™ MAC-3 weak acid cation resin |
| Softening - Gryllus process | Removal of calcium prior to evaporation, using thick juice as regenerant | DOWEX MONOSPHERE™ C600B strong acid cation resin |
| Softening - NRS process | Removal of calcium prior to evaporation, using NaOH as regenerant | DOWEX™ HCR-S strong acid cation resin or DOWEX MARATHON™ C-10 strong acid cation resin or DOWEX MONOSPHERE™ C600B strong acid cation resin |
| Quentin process | Removal of calcium prior to evaporation, replacing calcium with magnesium ion | DOWEX MONOSPHERE™ C600B strong acid cation resin |
| Softening of thin juice- especially when recovering sucrose from molasses | Used only prior to chromatographic separation | DOWEX™ MAC-3 weak acid cation resin |
| Chromatographic separation of molasses | Sucrose recovery of molasses | DOWEX MONOSPHERE™ 99K 320/350 chromatographic separation resins |
| Decolorization | Removal of color from beet solutions | DOWEX MARATHON™ MSA strong base anion resin DOWEX OPTIPORE™ SD-2 adsorbent |
| Chromatographic Extract Quality Improvement | Treatment of the sucrose product stream from chromatographic sucrose recovery to reduce color and foaming, making extract processing more profitable | DOWEX OPTIPORE™ SD-2 adsorbent |
| Sugar inversion | Conversion of saccharose (sucrose) to glucose and fructose | DOWEX™ 50Wx4 strong acid cation resin DOWEX™ 88 (H) strong acid cation resin |
