Objective

To evaluate Enzymol Protect B as a molasses preservative for maintaining the quality and fermentable sugar content of stored C-heavy molasses during extended storage, while minimizing deterioration under variable storage conditions.
The trial focused on maintaining TRS stability, controlling quality deterioration, and establishing a practical preservation regime for large-volume molasses storage.

Plant Profile

Industry: Sugar & Molasses-Based Distillery
Region: North India
Feedstock: C-heavy molasses
Application: Preservation of stored molasses
Storage: Multiple molasses storage tanks
Preservative dosing: Enzymol Protect B @ 10 ppm
Dosing frequency: Approximately every 15 days
Storage monitoring: TRS, Brix, pH, and temperature

The program was implemented across multiple storage tanks, including Tanks 3, 6, 8, 9, 10 and 11, with substantial molasses inventories under monitored storage conditions.

Process Challenge

  • Maintaining fermentable sugar during prolonged storage
  • Large quantities of C-heavy molasses were held in storage for extended periods, creating the challenge of preserving the available fermentable sugar rather than allowing gradual deterioration
  • Protecting molasses quality under fluctuating temperatures
  • Storage temperatures varied considerably, with recorded temperatures reaching 44°C, creating a demanding environment for maintaining molasses stability
  • Controlling quality variation across multiple storage tanks
  • Different tanks carried different molasses quantities and showed variations in Brix, TRS, and pH, requiring a consistent preservation strategy across the storage system
  • Preventing deterioration of valuable sugar reserves
  • Even a relatively small loss in TRS across several hundred thousand quintals of stored molasses can represent a significant loss of potentially recoverable sugar
  • Establishing a repeatable preservation regime
  • The plant required a practical dosing system that could be applied consistently across multiple tanks rather than relying on tank-specific corrective intervention

CATALYSTS Solution — Enzymol Protect B

  • Enzymol Protect B was applied at 10 ppm directly as a preservation treatment for stored C-heavy molasses
  • The treatment was implemented across multiple storage tanks and maintained through a planned approximately 15-day dosing cycle
  • Continuous circulation of stored molasses was recommended to support uniform treatment throughout the tank
  • Storage conditions were monitored through TRS, Brix, pH, and temperature, providing a structured basis for evaluating molasses stability
  • Joint laboratory analysis and triplicate TRS testing were incorporated to improve the reliability of the monitored storage data
  • This makes the solution section feel like an actual preservation program, rather than simply saying that a product was “added “

Performance Highlights

357,929 Qtl of molasses monitored

The six key treated tanks represented approximately 357,929 quintals of stored molasses in the reported monitoring snapshot

10 ppm preservation dosage

Enzymol Protect B was consistently applied at 10 ppm, providing a defined and repeatable treatment regime

~358 kg total product requirement

For the reported treated inventory, the corresponding Enzymol Protect B requirement was approximately 358 kg

TRS remained within a relatively narrow range

Across the monitored tanks, TRS remained broadly around 48–49%, despite extended storage and significant temperature variation

Storage conditions remained actively monitored

The program tracked TRS, Brix, pH and temperature over multiple months, providing a more robust assessment than a single end-point measurement

Storage Performance

A particularly useful way to present the report is to compare the earliest recorded TRS with the latest recorded TRS for each treated tank.

Tank Earliest TRS (%) Latest TRS (%) Change
Tank 8 49.32 48.55 ↓ 1.56%
Tank 10 49.32 48.04 ↓ 2.60%
Tank 9 48.42 48.04 ↓ 0.79%
Tank 3 48.80 48.32 ↓ 0.98%
Tank 11 48.56 47.95 ↓ 1.26%

Across these five tanks, average TRS moved from approximately 48.89% to 48.18%, representing only ~1.45% relative reduction over the respective monitoring periods.

That is a much stronger case-study statement than simply saying “TRS was maintained.”

Key Outcomes

  • Average monitored TRS remained approximately 48.2% at the latest readings, despite extended storage
  • Across five tanks with comparable first/latest readings, average TRS declined by only ~1.45% relative to the initial recorded level
  • Tank 9 showed the lowest relative TRS reduction at ~0.79%, followed by Tank 3 at ~0.98%
  • The highest relative reduction among these tanks was ~2.60% in Tank 10, while still retaining a final TRS of 48.04%
  • The preservation program was implemented across approximately 357,929 Qtl of molasses in the reported tank inventory
  • Enzymol Protect B dosing was standardized at 10 ppm, creating a consistent preservation protocol across multiple tanks
  • The monitoring program demonstrated the ability to maintain molasses quality across varying storage temperatures, including conditions reaching 44°C

Conclusion

The Enzymol Protect B program demonstrated a practical and controlled approach to preserving C-heavy molasses during storage. Across multiple tanks and extended monitoring periods, TRS remained broadly within the 48–49% range, with the five comparable tanks showing an average relative TRS reduction of approximately 1.45% from their respective earliest recorded values.

The results support Enzymol Protect B as a structured molasses-preservation solution for large-volume storage systems, particularly where maintaining fermentable sugar value over time is critical.
