Compare tannase with pectinase, amylase, protease, beta-glucanase, and other beverage enzymes. Learn where tannase fits for clarity, astringency control, flavor refinement, and extract performance.
Request pricingBeverage enzyme selection is not a generic choice. A pectin problem, a starch problem, a protein problem, and a tannin problem each require a different tool.
Tannase (Tannin Acyl Hydrolase) is the enzyme class used when the limiting factor is tannin chemistry: astringency, tea cream, polyphenol haze, extract roughness, or controlled release of gallic acid from hydrolysable tannins. It does not replace the full beverage enzyme toolbox. It gives formulation scientists and processors a precise option when polyphenols are the variable that needs control.
Use tannase when the process target is one or more of the following:
Use other beverage enzymes when the dominant issue is pectin, starch, protein, glucan, lactose, or oxygen management.
| Enzyme class | Primary target | Typical beverage role | Where tannase is different |
|---|---|---|---|
| Tannase | Hydrolysable tannins and galloyl ester linkages | Astringency control, tea cream reduction, phenolic refinement, extract clarity | Works directly on tannin structure and polyphenol behavior |
| Pectinase | Pectin | Fruit mash breakdown, juice yield, viscosity reduction, clarification | Does not target tannin ester bonds; often paired when fruit structure and tannins both matter |
| Amylase | Starch | Starch conversion in cereal, malt, and grain-based beverages | Helps carbohydrate processing, not astringency or tannin-driven haze |
| Protease | Proteins and peptides | Protein haze reduction, mouthfeel adjustment, fermentation nutrition support | Addresses protein instability, not polyphenol conversion |
| Beta-glucanase | Beta-glucans | Filtration improvement in barley, oats, and grain streams | Reduces glucan viscosity, not tannic bite |
| Cellulase / hemicellulase | Plant cell wall polysaccharides | Extraction support, mash breakdown, yield improvement | Releases material from plant structure; tannase then may refine tannin behavior |
| Lactase | Lactose | Lactose reduction in dairy-based beverages | Not relevant to tannin management |
| Glucose oxidase / catalase systems | Glucose and oxygen/peroxide balance | Oxygen control, stability strategies, specialty processing | Redox and shelf-life role, not tannin hydrolysis |
The key distinction: tannase is not a general clarification enzyme. It is a tannin-management enzyme.
Tannase catalyzes the hydrolysis of ester bonds found in certain tannins, especially hydrolysable tannins such as gallotannins. In practical terms, this can shift how tannins behave in the finished product:
This is why tannase is often evaluated in tea, instant tea, botanical extracts, fruit and plant beverages, wine-adjacent processing, coffee and cocoa extracts, and functional ingredient systems where polyphenols are commercially important but difficult to control.
Pectinase is one of the most familiar beverage enzymes because it improves pressability, viscosity, juice yield, and clarification in fruit systems. It works on pectin, a structural polysaccharide.
Tannase works on tannin chemistry.
A beverage can be hazy because of pectin. It can also be hazy because polyphenols interact with proteins, caffeine, minerals, or other colloids. These problems can look similar in a glass but respond differently in process.
Use pectinase when:
Use tannase when:
Use both when: fruit or botanical processing requires better extraction and a cleaner phenolic profile. Pectinase can open the matrix; tannase can refine the tannin fraction.
Proteases reduce proteins into smaller peptides and amino acids. In beverage applications, they may be used to manage protein haze, influence mouthfeel, or support fermentation nutrition.
Tannase does not digest protein. It changes the tannin side of the interaction.
This matters because many haze and astringency issues are caused by protein-polyphenol complexes. A protease-first approach changes the protein fraction. A tannase-first approach changes the tannin fraction. The better choice depends on product identity and sensory goals.
For premium beverages, tannase can be attractive when the goal is to reduce harshness without broadly degrading proteins that contribute body, foam, or mouthfeel.
Amylase and beta-glucanase are workhorse enzymes in grain, malt, cereal, and brewing-related streams.
These enzymes can improve yield and processability, but they do not directly resolve tannic bite, tea cream, or phenolic harshness.
If a grain-based or botanical beverage has both viscosity and astringency problems, carbohydrate enzymes may improve throughput while tannase addresses the sensory and phenolic layer.
Tea is one of the clearest application areas for tannase. Polyphenols are central to tea identity, but they also drive cream formation, turbidity, and dry astringency. Tannase can help processors build cleaner, more soluble tea bases for ready-to-drink, powdered, or concentrated formats.
Practical evaluation points:
Many botanicals contain meaningful tannin loads. That can be positive for positioning but difficult for taste and solubility. Tannase can help refine extracts intended for beverages, syrups, shots, powders, and liquid concentrates.
Useful targets include:
Tannase may support phenolic control in tannin-bearing fruit systems, especially where peel, seed, stem, or botanical solids contribute roughness. It is not a substitute for winemaking style decisions, fining, or maturation strategy, but it can be part of a controlled phenolic management program.
Evaluation should focus on sensory direction, color stability, turbidity, filtration behavior, and regulatory fit for the intended market.
In coffee, cocoa, and roasted or fermented plant extracts, tannins can interact with bitterness, acidity, and perceived dryness. Tannase can be explored where the product brief calls for smoother taste while preserving origin character and color depth.
Bring tannase into screening when your team sees one of these patterns:
A precise enzyme is valuable partly because it has boundaries.
Tannase will not:
The best tannase programs begin with a defined problem statement: what is the tannin-related defect, and what finished-product attribute should improve?
For B2B development, tannase screening should be built around the real beverage matrix, not only a model solution. Important variables include:
A good pilot compares tannase against the current process, not against an idealized lab sample. Measure what matters commercially: clarity stability, sensory acceptance, filterability, concentration behavior, and finished-product consistency.
Common in fruit, tea-fruit, and botanical matrices where both plant structure and polyphenol behavior matter. Pectinase supports juice release and viscosity reduction; tannase refines the tannin fraction.
Useful when extraction from plant solids is limiting yield, but higher extraction also brings more tannin. Cell-wall enzymes can increase release; tannase can help keep the resulting extract cleaner and less aggressive.
Tannase can reduce the tendency of certain tannins to form haze or sediment, while filtration and stabilization remove remaining insoluble material. The goal is not to eliminate downstream operations but to make them more predictable.
When tannase softens excessive dryness, flavor systems can be built with less masking pressure. This can be especially valuable in low-sugar, premium, botanical, and functional beverages.
Before requesting a quote or pilot sample, prepare the details that influence fit:
This information helps define whether tannase should be screened alone, paired with other enzymes, or held for a later optimization stage.
Tannase earns its place when tannins are not just present but operationally important. In the right matrix, it can sharpen clarity control, reduce phenolic roughness, improve extract usability, and give development teams another lever beyond dilution, masking, fining, or heavy filtration.
It is not the broadest beverage enzyme. It is the more specific one. That specificity is the point.
If you are comparing tannase with other beverage enzymes, Tannora can help frame a practical screening plan around your product matrix, process window, and commercial target.
