Overview

A leading sugar manufacturing facility was looking to improve starch control across critical process streams to support smoother sugar processing and better downstream performance. To address this requirement, The Catalysts Group evaluated Enzylase at a dosage of 5 ppm and monitored starch levels across key juice, syrup, massecuite, and molasses streams.

The evaluation demonstrated a significant reduction in starch levels, with reductions of 61–89% across the streams where before-and-after comparison was available, and an overall reported average reduction of 77%.

Process Challenge

  • Elevated starch levels across the process can contribute to increased viscosity and processing difficulties
  • Starch can interfere with crystallization and downstream sugar recovery
  • Effective starch control was required across multiple process streams to improve overall processability
  • The plant required an enzyme solution capable of delivering consistent starch reduction under commercial operating conditions

Catalysts Solution

The Catalysts Group implemented Enzylase at 5 ppm as a targeted starch-control solution. The enzyme was evaluated across multiple stages of sugar processing, with starch levels monitored before and after application to assess its effectiveness. Continuous process monitoring helped evaluate the reduction achieved across juice, syrup, massecuite, and molasses stream .

Performance Highlights

The Enzylase application delivered substantial starch reduction across the monitored process streams:
  • Achieved an overall reported 77% average reduction in starch across the streams with available before-and-after comparison
  • Achieved the highest reduction of 89% in Unclarified Sulphur Syrup
  • C.J.: Achieved 83% reduction
  • A M/C & A Heavy: Achieved 82% and 80% reduction, respectively
  • B M/C & B Heavy: Achieved 79% and 71% reduction, respectively
  • C M/C & Final Molasses: Achieved 73% and 61% reduction, respectively
  • Overall: Achieved 61–83% reduction across C.J., A M/C, A Heavy, B M/C, B Heavy, C M/C and Final Molasses
