Tannase for botanical extract processing
Tannora tannase helps manufacturers work with tannin-rich botanicals where astringency, haze, slow filtration, or unstable color can limit extract quality. By hydrolyzing ester-linked gallotannins and related tannin structures, tannase supports a more controlled polyphenol profile without stripping the botanical identity that gives an extract its commercial value.
For tea, oak, gallnut, grape, pomegranate, acerola, persimmon, medicinal herbs, and other polyphenol-dense materials, tannase can be used as a targeted processing aid for flavor refinement, clarification support, downstream standardization, and specialty ingredient development.
What tannase changes in an extract
Tannins can be valuable actives, but they can also create processing friction. Excessive tannin load may bind proteins, interact with minerals, form haze, increase perceived dryness, and complicate concentration or drying.
Tannora tannase is applied to modify selected tannin fractions so the extract becomes easier to process and easier to formulate.
Key outcomes may include:
- Reduced harsh astringency and drying mouthfeel
- Improved extract clarity and lower haze tendency
- Better filterability and smoother downstream handling
- More consistent polyphenol behavior between botanical lots
- Support for gallic-acid-enriched or modified extract positioning
- Improved compatibility in beverages, capsules, gummies, syrups, and liquid concentrates
Application fit
Botanical and herbal extracts
In herbal extraction, tannase can help refine high-tannin matrices that otherwise taste aggressive or create precipitation in finished formats. It is especially relevant where extract identity must remain intact while sensory harshness is reduced.
Common use cases include:
- Bitter or astringent herbal tinctures and liquid extracts
- Botanical concentrates for functional beverages
- Extracts designed for gummy, syrup, or shot formats
- Standardized polyphenol ingredients requiring better solubility behavior
Tea and tea-derived ingredients
Tea extracts can deliver valuable catechins and polyphenols, but tannin-driven haze and bitterness often create formulation limits. Tannase treatment can help soften the profile and support cleaner appearance in ready-to-drink systems, powders, and concentrates.
Potential benefits include:
- Less puckering and lingering dryness
- Improved clarity in liquid tea extracts
- Better performance in blends with minerals, proteins, acids, or sweeteners
- More controlled behavior during concentration and storage
Grape, pomegranate, and fruit polyphenol extracts
Fruit botanicals can contain complex tannin structures that influence color, sediment, and sensory balance. Tannase can be used as a precision step to reduce excessive astringency while preserving the premium, polyphenol-rich character of the source material.
Relevant goals include:
- Smoother taste in concentrated formats
- Reduced sediment formation risk
- Better compatibility in beverage bases and nutraceutical systems
- Support for differentiated specialty extract profiles
Gallnut, oak, and gallic-acid-oriented extracts
Where the target is a gallic-acid-enriched profile or a controlled transformation of hydrolyzable tannins, tannase can support process development. It is not a shortcut for good extraction design, but it can become a critical conversion step in a well-controlled botanical workflow.
Where tannase fits in the process
Tannase is typically evaluated after extraction and before final clarification, concentration, or drying. The most effective process point depends on raw material, solvent system, solids load, target profile, and downstream format.
A common development sequence:
- Extract the botanical under the selected solvent, temperature, and pH conditions.
- Remove coarse solids to reduce non-productive binding and handling issues.
- Apply tannase under controlled mixing and residence time.
- Monitor sensory, turbidity, filtration behavior, and target marker profile.
- Stop or separate the enzyme step according to the validated process design.
- Clarify, concentrate, blend, or dry as required.
Process parameters to define during trials
Every botanical matrix behaves differently. Tannora recommends bench screening before pilot scale so the process window is defined around the product objective rather than a generic addition rate.
Parameters to optimize:
- Botanical species, origin, and seasonal variation
- Extraction solvent and water activity
- pH and buffer capacity of the extract
- Temperature tolerance of sensitive actives
- Solids level and viscosity
- Contact time and mixing intensity
- Degree of tannin conversion desired
- Downstream clarification, membrane, evaporation, or drying conditions
The aim is not always maximum tannin breakdown. In premium extracts, the better target is controlled modification: enough conversion to improve processability and taste, while retaining the botanical structure, color, and analytical identity required by the finished product.
Benefits for ingredient manufacturers
Cleaner sensory profile
Tannase can reduce the hard edge of tannin-heavy extracts. This is especially useful when developing formats consumed directly, including functional beverages, shots, liquid supplements, gummies, lozenges, and sachets.
More predictable clarification
By changing tannin interactions with proteins, minerals, and colloids, tannase can support lower haze tendency and more efficient clarification. This can help reduce rework and improve batch-to-batch consistency.
Better formulation compatibility
High-tannin extracts can destabilize finished products, particularly in acidic beverages, mineral systems, dairy alternatives, and protein-containing formulations. Tannase treatment can help make the extract easier to blend without losing its botanical positioning.
Specialty extract differentiation
Tannase enables more than problem-solving. It can support new extract concepts, including smoother high-polyphenol ingredients, gallic-acid-oriented profiles, and premium botanical bases designed for clean-label functional products.
Development notes
Tannase performance should be evaluated against the commercial specification, not only against a single analytical marker. Recommended trial endpoints include:
- Sensory reduction in astringency and bitterness
- Turbidity before and after heat or acid challenge
- Filtration time or membrane behavior
- Precipitation tendency during storage
- Polyphenol marker profile
- Color stability
- Finished-product compatibility
For regulated ingredient programs, document the enzyme processing step, inactivation or removal strategy if applicable, and the relationship between treatment conditions and finished extract specifications.
