CPG Sec. 515.425 Sugar - Water Damaged - Reconditioning
The Center for Food Safety and Applied Nutrition has agreed to the following refining process for reconditioning water damaged sugar:
- Introduce sugar into refining process at site of high raw sugar melter or "high remelt" melter.
- Determine if sugar condition warrants lime, P205, etc. treatment.
- Mix with water or process juices to a 65-70 percent concentration.
- Maintain temperature at 95oC (203oF) or greater.
- Add filter aid or diatomaceous earth and pass process sirup through clarifiers or pressure filters and continue through char, *carbon, and/or ion exchange resin* filters to improve color.
- Introduce filtered liquors into vacuum pans and boil to point of supersaturation.
- Introduce seed crystals and continue crystal growth to optimum size.
- Centrifuge, wash with hot water, and dry in granulator.
- Place in bulk refined storage or screen to desired commercial product size.
- The supernate and centrifugal washings are returned to normal process stream.
The above method is suitable for reconditioning sugar damaged by non-potable fresh or salt water.
NOTE: The method is not suitable for reconditioning sugar if there is evidence that the sugar was damaged by chemicals or sewage (floods, flooded ship's toilet, etc.).
