Bleaching and Blending

Inline Control

Monitoring color inline using optek photometers enables precise, real-time control of color dosing, color removal, color quality or color avoidance.

Typically, process color measurements are made by taking samples from the process piping and analyzing them in a lab either visually or using a laboratory analyzer. optek colorimeters can immediately detect color changes in process liquids directly in the pipeline.

Typical Applications:

Edible Oil:
  • Control of bleaching process / bleach dosing / control of filter breakthrough
Potato Processing:
  • Dosing control of caramel color, annatto or tumeric
Sugar Refining:
  • Decolorization of sugar, monitoring of the fine liquor, ICUMSA/RBU color measurement
Fruit Juice:
  • Precise juice color monitoring


  • Real-time measurements / less need for lab analysis
  • Consistent product quality
  • Measurement wavelengths and optical path lengths selected to match process requirements
  • Immediate feedback on process changes
