Sorbitol Purification

Sorbitol is widely used in the pharma and cosmetic industry. It is a water-soluble polyhydric alcohol with a sweet taste and high stability, besides possessing properties of humectancy and plasticising.

Highly purified and specifically processed Tulsion® speciality ion exchange resins are extensively used in manufacturing of high quality sorbitol.

Tulsion® Ion Exchange Resins in Sorbitol Processing

Starch is subjected to acid or enzyme hydrolysis to obtain starch hydrolysate. This purified hydrolysate is then passed through a Demineralisation unit containing Tulsion® strong acid cation exchange resin, followed by a weak base anion exchange resin. The deionised liquid glucose syrup is further subjected to carbon treatment for polishing before sending it for Sorbitol manufacturing.
