Dow offers a wide variety of resins integral to processing corn syrup, high-fructose corn syrup and other starch-based syrups. Dow resins and adsorbents are used in five major unit processes in corn sweetener processing: de-ashing, chromatographic separation of dextrose and fructose, chromatographic purification of dextrose, mixed bed polishing and color removal.
Without ion exchange resins, corn wet-milling used to produce dextrose, high fructose corn syrup (HFCS), very high purity HFCS and crystalline fructose could not exist.
