Tannase for Tannin Reduction in Plant Ingredients
Plant ingredients often carry the compounds that make them valuable — polyphenols, botanical character, color, and antioxidant positioning. The same matrix can also bring tannin-driven bitterness, astringency, darkening, haze, protein binding, and extraction inefficiency.
Tannora supplies Tannase (Tannin Acyl Hydrolase) for evaluation in plant ingredient workflows where tannins need to be controlled without stripping away the identity of the raw material.
Where tannase fits
Tannase hydrolyzes ester-linked tannin structures and can help shift the phenolic profile of plant-derived materials. In practice, teams evaluate it to support:
- Bitterness and astringency reduction in botanical extracts, tea solids, fruit-derived ingredients, and plant protein systems
- Color and clarity improvement where tannins contribute darkening, haze, or instability
- Improved extract performance by reducing tannin interactions that can limit release, filtration, or concentration
- Better formulation behavior when tannins bind proteins, minerals, emulsifiers, or stabilizers
- More controlled sensory outcomes in premium plant-based beverages, concentrates, and functional ingredients
The objective is not generic “debittering.” It is controlled tannin management: enough transformation to improve process and sensory performance while preserving the ingredient’s intended character.
Relevant plant ingredient applications
Plant protein concentrates and isolates
Tannins can bind proteins and contribute to a dry, puckering finish. In selected plant protein workflows, tannase may be evaluated upstream or during aqueous processing to reduce tannin-related astringency and improve downstream formulation quality.
Typical evaluation goals include:
- Lower perceived astringency in finished protein beverages or powders
- Reduce tannin-protein interaction during extraction or clarification
- Improve compatibility with flavors, sweeteners, minerals, and hydrocolloids
- Support cleaner sensory positioning for premium plant-based products
Tea, herbal, and botanical extracts
Tea leaves, herbs, barks, peels, seeds, and other botanicals can carry high phenolic loads. Tannase can be used to refine extracts where tannins create harshness, excessive dryness, dark color, or precipitation risk.
Teams often evaluate tannase for:
- Smoother extract taste without flattening botanical identity
- Improved brightness in liquid concentrates
- Better stability before concentration or drying
- More consistent extract quality across variable raw materials
Fruit, seed, and polyphenol-rich ingredients
Pomegranate, grape, persimmon, berry, nut, seed, and similar inputs may present tannin-related processing challenges. Tannase can help convert targeted tannin fractions and may support a cleaner balance between phenolic intensity and product usability.
Evaluation focus areas include:
- Reducing harsh phenolic edges
- Improving filtration or separation behavior
- Managing color development during processing
- Enhancing usability in beverages, gummies, powders, and functional blends
Process positions to evaluate
Tannora tannase can be considered at several points depending on the raw material and desired outcome.
Upstream extraction
Use when tannins interfere with release, separation, or early-stage extract quality. This position is useful when the goal is to improve processing behavior before concentration or blending.
Mid-process refinement
Use when an extract, slurry, or liquid intermediate already exists and needs sensory or color adjustment before final specification.
Before concentration or drying
Use when tannin-driven darkening, haze, or instability becomes more significant after concentration, evaporation, or powder conversion.
What to define before a trial
A good tannase trial starts with the ingredient problem, not the enzyme alone. Before screening, define:
- Raw material source and seasonal variability
- Current processing sequence and hold points
- Target sensory change: bitterness, astringency, dryness, or aftertaste
- Target visual change: brightness, color depth, haze, or sediment
- Downstream steps such as filtration, concentration, drying, blending, or heat treatment
- Regulatory and labeling requirements for the intended market
- Acceptable process window for pH, temperature, contact time, and separation
Tannins are not one single chemistry. Some fractions respond more directly to tannase than others, and complex plant matrices may require combined process adjustments. Tannora helps structure evaluations so the first trial answers a practical production question.
Expected value for ingredient manufacturers
When the substrate and process are suitable, tannase evaluation may support:
- Cleaner, less puckering flavor profiles
- Brighter extracts and improved visual quality
- Reduced tannin-related haze or sediment risk
- Better interaction with proteins and stabilizing systems
- More consistent performance from variable botanical inputs
- Improved yield or usability of phenolic-rich plant materials
