Improving fermentation efficiency involves more than selecting the right yeast or optimizing starch conversion. Even when liquefaction and saccharification work effectively, some carbohydrate fragments may remain unfermented. As a result, manufacturers may lose potential alcohol yield despite using suitable raw materials and maintaining a well-managed fermentation process.
A fermentation booster enzyme helps address this challenge by converting certain unfermentable sugars into fermentable sugars that yeast can use. For grain-based fermentation, Leaf CleanTech offers BOOSTERZYME, an enzyme solution designed to improve fermentation efficiency by acting on unfermentable sugars.
By targeting residual sugars, a fermentation booster can complement alpha amylase, glucoamylase and active dry yeast. Therefore, it provides another option for manufacturers who want to evaluate yield improvement within their existing grain fermentation process.
A fermentation booster enzyme is an enzyme preparation used to improve the utilization of sugars during fermentation. In grain processing, starch first undergoes liquefaction and saccharification. These steps break complex starch structures into smaller carbohydrates and fermentable sugars.
However, conventional starch conversion may leave some residual carbohydrates that yeast cannot readily ferment. A suitable booster enzyme targets this gap and helps release additional fermentable sugars from specific unfermentable carbohydrate fractions.
Consequently, the process may improve sugar utilization and support better overall fermentation performance. The actual result depends on the raw material, enzyme dosage, operating conditions and the composition of the residual sugars.
Grains such as corn, rice, wheat, sorghum and millets contain starch with complex molecular structures. Enzymes break down this starch in stages, but the conversion may not be complete under every operating condition.
Several factors can contribute to residual carbohydrate levels:
Therefore, manufacturers should assess the complete process before selecting an additional enzyme. A booster enzyme is most relevant when residual unfermentable sugars contribute to the gap between expected and actual fermentation performance.
Leaf CleanTech's BOOSTERZYME is designed for grain fermentation applications. It acts on unfermentable sugars, helping convert them into fermentable sugars that yeast can use during fermentation.
The enzyme complements the main processing stages rather than replacing the core enzymes or yeast. This allows manufacturers to assess its role as part of their existing fermentation workflow.
As a result, the booster enzyme complements the existing enzyme system. For a broader overview, read our grain fermentation process enzymes guide.
Each enzyme in grain fermentation has a specific role. Choosing the right combination helps manufacturers address different stages of starch conversion and sugar utilization.
| Enzyme or Ingredient | Primary Function | Process Stage | Role in Fermentation |
|---|---|---|---|
| High-temperature bacterial alpha amylase | Breaks starch into shorter dextrins and reduces mash viscosity. | Liquefaction | Prepares starch for further enzymatic conversion. |
| Glucoamylase | Converts starch-derived dextrins into fermentable glucose. | Saccharification | Supplies sugars that yeast can ferment. |
| Active dry yeast | Metabolizes fermentable sugars. | Fermentation | Converts available sugars into ethanol and carbon dioxide. |
| Fermentation booster enzyme | Acts on certain unfermentable sugars to help release fermentable sugars. | During fermentation, according to the process protocol | Supports additional sugar utilization and potential yield improvement. |
These solutions serve complementary purposes. For example, alpha amylase and glucoamylase support starch conversion, while yeast performs fermentation. A booster enzyme addresses certain residual sugars that the earlier stages may leave behind.

Residual unfermentable sugars may represent a portion of the carbohydrate content that the fermentation process does not fully utilize. A suitable booster enzyme can help make some of these sugars available to yeast, supporting more effective substrate utilization.
When residual unfermentable sugars limit performance, targeted enzymatic action may improve overall fermentation efficiency. However, the benefit depends on the type and quantity of residual sugars present in the mash.
BOOSTERZYME is designed to complement the grain fermentation process. It works alongside the roles of alpha amylase, glucoamylase and yeast, allowing manufacturers to evaluate an additional route to sugar recovery.
Manufacturers can compare fermentation results before and after introducing a booster enzyme. By tracking residual sugars, fermentation time and final alcohol yield, they can determine whether the enzyme provides a meaningful process benefit.
If the main starch conversion stages already perform well, investigating unfermentable sugars may reveal another opportunity for improvement. A controlled trial helps establish whether this approach suits the specific production process.
A fermentation booster enzyme may be worth evaluating when a grain fermentation plant experiences one or more of the following conditions:
Nevertheless, low alcohol yield does not always indicate a need for a booster enzyme. Incomplete liquefaction, poor saccharification, unsuitable yeast, contamination and inconsistent operating conditions can also affect performance. A process review can help identify the underlying cause before making changes.
Before introducing a fermentation booster enzyme at production scale, conduct a controlled trial using a representative feedstock and established process conditions.
This approach helps manufacturers make decisions based on measurable results rather than assumptions. It also makes it easier to identify the operating conditions under which the enzyme provides the greatest benefit.

A fermentation booster enzyme is used to help improve sugar utilization during fermentation. In grain fermentation, BOOSTERZYME acts on certain unfermentable sugars to help convert them into fermentable sugars that yeast can use.
Unfermentable sugars are residual carbohydrate fractions that yeast cannot readily ferment directly under the process conditions. They may remain after liquefaction and saccharification, depending on the raw material and process performance.
BOOSTERZYME is designed to act on unfermentable sugars during grain fermentation, helping make additional fermentable sugars available to yeast. The actual benefit depends on the substrate and operating conditions.
Glucoamylase primarily converts starch-derived dextrins into fermentable glucose during saccharification. A fermentation booster enzyme targets certain unfermentable sugars that remain in the process, so the two solutions serve different but complementary roles.
A suitable booster enzyme may improve alcohol yield when residual unfermentable sugars limit fermentation performance. However, the result depends on the feedstock, process conditions and quantity of sugars available for conversion. Controlled trials help verify the benefit.
No. Alpha amylase supports starch liquefaction, while glucoamylase supports saccharification. BOOSTERZYME is designed to complement these enzymes by targeting certain residual unfermentable sugars.
