Pullulanase Enzyme
1,000 – 3,000 ASPU/g
Applications
Pullulanase cleaves α-1,6 branch points in amylopectin and related polysaccharides, improving downstream amylase efficiency across starch conversion, brewing adjunct treatment, baking shelf-life control, and specialty carbohydrate manufacturing.
Starch Saccharification
Debranches amylopectin at α-1,6 linkages during saccharification, boosting glucose yield by 2–4% over amylase-only processes.
Learn more →High-Maltose Syrup
Prepares branched starch for optimal maltose formation, enabling syrups with >50% maltose content for confectionery and processed food applications.
Brewing Adjunct Processing
Improves fermentability of rice and maize adjuncts by reducing residual dextrins, ensuring consistent attenuation in lighter beer styles.
Baking — Anti-Staling
Modifies starch retrogradation and crumb texture to maintain softness and extend product shelf life.
Bioethanol Optimization
Applied with glucoamylase to achieve near-total starch conversion, maximizing ethanol yield per unit grain.
Cyclodextrin Production
Generates linear glucan chains for CGTase to convert efficiently into cyclodextrins.

Frequently Asked Questions
What does Pullulanase (EC 3.2.1.41) do in starch processing?
It cleaves α-1,6 branch linkages in amylopectin and pullulan, yielding linear chains that amylases convert more efficiently to glucose or maltose.
What are the recommended pH and temperature ranges for Pullulanase?
For best performance, operate at pH 4.0–5.5 and 55°C–65°C.
How should I interpret the activity value (1,000–3,000 ASPU/g)?
The value represents enzyme units per gram. Higher activity offers faster debranching; confirm dosing in your own process trials.
Can Pullulanase improve glucose yield compared with amylase alone?
Yes. Debranching exposes more substrate to amylase, often delivering 2–4% higher glucose output in saccharification operations.
How should I store Pullulanase to maintain activity?
Keep refrigerated and sealed to ensure 12-month shelf life. Avoid repeated temperature fluctuations; follow COA/TDS storage notes.
