Learn what tannase is, how it modifies hydrolyzable tannins, and why technical buyers use it for clarity, flavor refinement, yield improvement, and specialty extract performance.
Request pricingTannase, properly known as Tannase (Tannin Acyl Hydrolase), is an industrial enzyme used to modify tannins and related polyphenols in plant-based materials. In practical terms, it helps processors reduce harsh astringency, improve clarity, release gallic acid, support extraction efficiency, and create more controlled sensory profiles in beverages, extracts, fermentations, and functional ingredients.
For technical buyers, tannase is not a generic “processing aid.” It is a targeted tool for managing tannin behavior where polyphenols affect taste, haze, color, filtration, solubility, or downstream ingredient performance.
Tannase is an enzyme that hydrolyzes ester bonds in hydrolyzable tannins and gallate esters.
That reaction can convert complex tannin structures into smaller phenolic components, including gallic acid, depending on the substrate and process conditions. The result is often a cleaner flavor profile, improved liquor or extract handling, and more predictable behavior in finished systems.
Tannase is most relevant when tannin-rich raw materials are part of the process stream. Common application areas include:
Tannins are a broad class of plant polyphenols. They are responsible for much of the drying, puckering sensation associated with tea, wine skins, oak, some fruit extracts, and many botanicals.
Tannase is especially associated with hydrolyzable tannins, including gallotannins and related esterified phenolics. In a process setting, this matters because tannins can:
Tannase gives formulators and processors a way to alter those tannin structures rather than simply masking or removing them.
Tannase can reduce aggressive, drying tannic impact in selected plant-derived systems. This is particularly useful where the goal is not to eliminate character, but to make a beverage or extract taste cleaner, rounder, and more premium.
Tannin-protein interactions can create turbidity, sediment, or instability. By changing tannin structure, tannase can support clearer liquids and more predictable clarification behavior.
In botanical and plant extract manufacturing, tannase may help release target phenolics, reduce binding effects, and improve the consistency of extract performance across variable raw materials.
High-tannin substrates can be challenging for microbial systems. Tannase can reduce inhibitory tannin effects in certain fermentations, helping teams improve conversion behavior and process reliability.
Tannase is widely recognized for its ability to help produce gallic acid from gallotannin-rich materials. This makes it valuable in specialty phenolic ingredient streams and selected chemical-biological conversion processes.
Tannase performance depends on the substrate, process matrix, temperature, pH range, contact time, and the desired sensory or chemical outcome. The same enzyme can be used differently in tea extraction, wine processing, botanical extraction, or fermentation support.
When evaluating tannase, buyers typically define:
A well-specified tannase trial should be built around the business result: cleaner taste, lower haze, higher usable extract, improved conversion, or a more controlled phenolic profile.
Tea is one of the most recognizable tannase applications. Black tea, green tea, instant tea, and RTD tea systems can develop bitterness, astringency, cream formation, or cold-storage haze due to polyphenol interactions.
Tannase can help beverage processors:
For premium beverage systems, the objective is balance: maintain tea identity while reducing instability and excessive bite.
Botanical extracts often contain complex phenolic matrices. Depending on the plant source, tannins may contribute useful character or create problems in solubility, taste, color, and stability.
Tannase is used to make these systems more manageable. It can support cleaner liquid extracts, improve downstream filtration, and help ingredient manufacturers standardize performance when raw botanical lots vary seasonally.
Some fermentation substrates contain tannins that bind nutrients, inhibit microbes, or reduce accessibility of fermentable components. In these systems, tannase may be used as a pretreatment or process aid to reduce tannin interference.
Typical goals include:
The fit depends heavily on the organism, substrate, and production target, so bench evaluation is essential.
Tannase is not a universal debittering solution, and it does not replace good raw material control. It is also not interchangeable with pectinase, cellulase, protease, or amylase. Those enzymes act on different substrates.
Tannase is best used when the limiting factor is tannin chemistry: astringency, haze, phenolic binding, gallate ester conversion, or polyphenol-driven process instability.
Before sourcing tannase, technical teams should prepare a concise application brief. Useful details include:
This allows the supplier and buyer to align on practical performance rather than broad claims.
