Thaumatin — E 957
Thaumatin is an intensely sweet, water-soluble protein preparation traditionally obtained from the arils surrounding the seeds of the West African katemfe plant, Thaumatococcus daniellii. It is used at very low levels for sweetness enhancement, flavor modification, bitterness masking and long-lasting taste effects.
Commercial Thaumatin is composed principally of closely related sweet proteins, especially Thaumatin I and Thaumatin II. These proteins have a compact, disulfide-bonded structure that supports useful stability under selected acidic and thermal processing conditions.
Thaumatin is not a polyol, humectant, bulking ingredient or direct one-for-one sugar replacement. Its industrial value lies in sensory intensity and flavor modification. Sugar-reduced products still require separate control of solids, texture, water activity, freezing point, browning and process behavior.

Primary technical functions
- High-intensity sweetness: provides substantial sweetness at a very low ingredient mass.
- Sweetness persistence: creates a longer-lasting sweetness finish than sucrose in many applications.
- Bitterness masking: may reduce the perception of selected bitter compounds in nutrition, botanical and reduced-sugar systems.
- Flavor modification: can change flavor balance, duration and perceived intensity.
- Aftertaste management: may help rebalance aftertastes associated with some high-intensity sweeteners.
- Flavor extension: can support prolonged mint, fruit, spice or confectionery flavor perception.
- Reduced-sugar formulation: can replace part of the sweetness lost when sugar is reduced.
- Sensory differentiation: can create a distinctive sweetness curve in chewing gum, lozenges and long-consumption products.
Sweetness intensity, onset and temporal profile
Thaumatin is often described as several thousand times sweeter than sucrose by weight. That comparison is only an approximate sensory reference because relative sweetness changes with concentration, product composition, temperature, pH, serving size and the time point at which sweetness is measured.
Sweetness onset
The sweetness of Thaumatin generally develops more slowly than sucrose. In products consumed quickly, this delayed onset may create a gap at the beginning of the taste experience.
A faster-onset sweetener or a small amount of sugar may be used to support the initial sweetness phase.
Sweetness duration
Thaumatin can remain perceptible after other sweeteners have declined. This persistence may be beneficial in chewing gum, lozenges, oral-care products and long-lasting flavor systems.
In beverages or delicate dairy products, excessive persistence may be perceived as artificial or unbalanced.
Concentration response
The sensory response is not necessarily linear. Doubling the ingredient dose does not guarantee twice the perceived sweetness or twice the bitterness-masking effect.
Development should use a closely spaced concentration ladder near the expected optimum.
Matrix dependence
Fat, protein, acids, salts, alcohol, hydrocolloids, flavor oils and other sweeteners can alter the apparent intensity and timing of Thaumatin.
Sensory conclusions from water solutions should not be transferred directly to the finished food.
Recommended temporal sensory assessment
| Sensory stage | Development question |
|---|---|
| Initial contact | Is sweetness present quickly enough for the product format? |
| Mid-palate | Does Thaumatin integrate with the primary flavor and other sweeteners? |
| Swallow | Is there a sudden increase or imbalance in sweetness? |
| Early aftertaste | Are bitterness, metallic notes or botanical off-notes reduced? |
| Late aftertaste | Is the lingering sweetness pleasant, excessive or licorice-like? |
| Repeat consumption | Does sweetness accumulate over multiple sips, bites or chews? |
Protein structure, sweetness and stability
Thaumatin's sweet taste depends on its three-dimensional protein structure and the presentation of charged and polar regions to the human sweet-taste receptor. Chemical or physical denaturation can therefore reduce sweetness even when the protein remains present analytically.
Disulfide-bonded structure
Multiple internal disulfide bonds help maintain the compact protein conformation. This contributes to useful stability compared with many less tightly folded proteins.
Strong reducing conditions, severe heat or incompatible chemical environments may disrupt the structure and reduce sweetness.
Protein denaturation
Denaturation can result from temperature, pH, alcohol, interfaces, proteolysis, agitation and interactions with other ingredients.
A clear solution does not necessarily prove that sweetness has been fully retained; sensory or activity-related evaluation may still be required.
Technical purchasing specification framework
Thaumatin specifications should distinguish regulatory identity, protein composition, functional potency and the composition of any standardized carrier system.
| Parameter | Purchasing requirement | Industrial significance |
|---|---|---|
| Product identity | Thaumatin / E 957 / INS 957 | Confirms the intended sweet-protein additive. |
| Biological source | Exact plant, extraction or alternative production source declared by the supplier | Source can affect regulatory status, claims, traceability and composition. |

Dissolution, premixing and low-dose distribution
Thaumatin's high sensory potency means that poor weighing or mixing can create significant batch variation. Directly adding a few grams of concentrated powder into a large batch is rarely the most robust industrial method.
Recommended liquid-premix sequence
- Confirm the active assay. Calculate the required product amount using the lot-specific potency.
- Select compatible water. Control pH, minerals, oxidants, microbiology and temperature.
- Establish gentle agitation. Avoid excessive foam and air-protein interfaces.
- Add gradually. Prevent local clumping and powder adhering above the liquid line.
- Mix until dissolved. Confirm absence of visible particles or sediment.
- Add sensitive ingredients carefully. Evaluate alcohol, tannins, polyphenols, salts and reducing agents.
- Verify pH and active concentration. Use actual batch mass rather than nominal tank volume alone.
- Use promptly or validate the hold period. Define temperature, light protection, hygiene and maximum storage time.
Dry premixing
- Use an approved carrier with compatible particle size.
- Apply geometric dilution.
- Control electrostatic charging.
- Avoid segregation during conveying.
- Verify premix homogeneity analytically or by a validated marker.
- Protect the premix from humidity.
Liquid premixing
- Provides accurate distribution at very low dosage.
- Can simplify addition to beverages and syrups.
- Requires microbiological control.
- Requires validated pH and hold time.
- May foam under excessive agitation.
- Must be protected from incompatible ingredients.
pH, heat, salts, alcohol and ingredient interactions
| Condition | Potential effect | Development action |
|---|---|---|
| Acidic pH | Thaumatin often retains useful solubility and sweetness under acidic conditions | Confirm the actual acid system, heat process and shelf life |
| Neutral or alkaline pH | Can increase susceptibility to heat-related structural change | Minimize severe heating and validate sweetness retention |
| Short heat process | May retain acceptable performance in a suitable acidic matrix | Measure before and after the actual pasteurization or hot-fill cycle |
| Prolonged high heat | Can denature or aggregate the protein and reduce sweetness | Evaluate late addition, protected grades or process redesign |
| Reducing agents | May affect disulfide bonds and protein conformation | Test the complete formulation and storage conditions |
| Proteolytic enzymes | Can hydrolyze the sweet protein and reduce activity | Review enzyme addition, native proteases and heat inactivation |
| Polyphenols and tannins | May bind proteins, create haze or alter flavor perception | Test tea, coffee, cocoa, botanical and fruit extracts directly |
| Alcohol | Can alter protein solubility and flavor release at higher concentrations | Evaluate the final alcohol level and addition sequence |
| High salt or ionic strength | May affect protein solubility and sensory perception | Use the final mineral and salt composition during testing |
| Freeze-thaw cycling | Can concentrate solutes and change protein interactions | Test frozen products through multiple realistic cycles |
| Long storage | Can change potency, solution clarity or sensory profile | Complete real-time packaged shelf-life testing |
Blending Thaumatin with sugars and other sweeteners
| Sweetener partner | Potential role of Thaumatin | Critical evaluation |
|---|---|---|
| Sucrose | Extend sweetness and permit partial sugar reduction | Bulk, texture, browning, preservation and temporal balance |
| Glucose or glucose syrup | Increase perceived sweetness without adding substantial solids | Flavor, browning, viscosity and crystallization |
| Polyols | Increase sweetness and potentially improve lingering profile | Cooling effect, digestive tolerance, laxative labeling and texture |
| Steviol glycosides | Modify bitterness and extend sweetness | Licorice-like overlap, delayed sweetness and total aftertaste |
| Sucralose | Add persistence or modify the sweetness curve | Excessive lingering and market-specific permissions |
| Acesulfame potassium | Support bitterness masking and temporal balance | Metallic or bitter notes and combined legal limits |
| Aspartame | Modify sweetness duration and flavor profile | Heat stability, pH, phenylalanine labeling and market authorization |
| Saccharin | Potentially reduce bitter or metallic perception | Aftertaste, intensity and destination-market restrictions |
| Fruit concentrates | Enhance fruit sweetness perception at low added solids | Acidity, tannins, natural sugar contribution and flavor authenticity |
Functions Thaumatin cannot replace
| Sugar function | Effect of sugar reduction | Separate formulation response |
|---|---|---|
| Bulk and solids | Reduced weight, body and solids content | Use permitted fibers, polyols, starches, proteins or other bulking systems |
| Water activity | Potentially shorter microbial shelf life | Redesign preservation, moisture and packaging controls |
| Viscosity | Thinner syrups, fillings and beverages | Optimize hydrocolloids, solids and process conditions |
| Freezing-point depression | Harder frozen products and larger ice crystals | Use appropriate soluble solids and freezing-point modifiers |
| Browning | Reduced caramelization and Maillard color | Adjust sugar profile, heat process or permitted color system |
| Fermentation substrate | Reduced yeast or culture activity | Maintain the required fermentable carbohydrate separately |
| Crystallization | Changed confectionery and coating structure | Redesign the carbohydrate and fat system |
| Mouthfeel | Reduced body and increased perception of acidity or bitterness | Rebalance solids, fat, protein, hydrocolloid and flavor |
Active-Thaumatin and batch-addition calculations
Thaumatin use levels are application-specific and should not be selected from a universal table. Sensory response, flavor masking, active content and local regulation determine the final dose.
Active-product calculation
Required product, mg/kg = target active Thaumatin, mg/kg ÷ product active fraction
A standardized product containing 10% active Thaumatin has an active fraction of 0.10.
Active contribution
Active Thaumatin, mg/kg = product addition, mg/kg × active fraction
The calculation should be based on the certified active basis used in the supplier specification.
Batch addition
Product mass, kg = batch mass, kg × product addition, mg/kg ÷ 1,000,000
Liquid concentrate
Concentrate mass = required active Thaumatin mass ÷ active fraction in concentrate
Correct volumetric dosing for concentrate density and temperature.
Recommended sensory dose-response study
- Prepare an untreated control.
- Prepare several closely spaced active-Thaumatin levels.
- Keep all other sweeteners and flavors constant.
- Evaluate initial sweetness, peak intensity and persistence.
- Score bitterness, metallic notes and licorice-like aftertaste.
- Repeat after the full heat process.
- Repeat after storage in the final package.
- Confirm the selected level against applicable legislation.
Potential food and flavor applications
The following are technical evaluation areas rather than universal permissions or fixed use levels. Suitability depends on the exact food category, function, grade and destination-market legislation.
| Application | Potential purpose | Critical validation points |
|---|---|---|
| Chewing gum | Long-lasting sweetness and flavor extension | Gum-base compatibility, release rate, aftertaste and legal use |
| Lozenges and compressed products | Persistent sweetness and bitterness masking | Premix uniformity, compression, dissolution and repeated-consumption profile |

Bitterness masking and off-note management
Thaumatin does not chemically remove bitter compounds. It changes the overall sensory balance and may reduce the perceived dominance of bitterness, astringency or metallic notes.
| Challenging component | Potential sensory issue | Development approach |
|---|---|---|
| Plant proteins | Beany, earthy, bitter or astringent notes | Combine Thaumatin with aroma correction, salt, fat and acidity control |
| Hydrolyzed proteins and peptides | Strong peptide bitterness | Use a dose-response study and evaluate protease activity |
| Mineral salts | Metallic, bitter or drying sensation | Optimize mineral form, chelation, acids, flavors and sweetener blend |
| Botanical extracts | Bitter, medicinal, woody or tannic character | Evaluate precipitation, haze, polyphenol binding and aftertaste |
| Caffeine | Persistent bitterness | Balance onset and late sweetness without creating excessive lingering |
| Cocoa | Bitterness and astringency | Test with the actual cocoa solids, alkalization level and fat system |
| High-intensity sweeteners | Metallic, licorice-like or delayed aftertaste | Optimize total temporal profile rather than only peak sweetness |

- Botanical sourcing: fruit is collected from approved and traceable plant sources.
- Aril separation: the sweet aril material is separated from seeds, skin and other plant matter.
- Cleaning: foreign material and unsuitable botanical matter are removed.
- Aqueous extraction: sweet proteins are transferred into a controlled water phase.
- Solid separation: insoluble plant material is removed through filtration or centrifugation.
- Protein purification: supplier-specific membrane, precipitation, adsorption or chromatographic operations may be used.
- Concentration: the purified protein solution is concentrated under controlled conditions.
- Microbial control: a validated process may be applied while protecting protein functionality.
- Drying: the concentrate is converted into a stable powder using a supplier-specific drying process.
- Milling and classification: particle size is adjusted for the intended grade.
- Standardization: a declared carrier may be added to achieve a target potency.
- Quality release: identity, assay, sensory quality, microbiology and purity are reviewed before packaging.
Food-allergen, occupational and cross-contact considerations
Food-product assessment
Thaumatin is a protein preparation. Its labeling and allergen status should be reviewed according to the destination market, production source, carrier ingredients and supplier evidence.
- Exact biological source
- Protein composition
- Carrier and processing-aid composition
- Shared-equipment cross-contact statement
- Destination-market allergen rules
- Customer allergen policies
Occupational exposure
Fine protein powder can pose an inhalation and sensitization risk to exposed workers. Food safety for oral use does not remove the need for workplace dust controls.
- Use enclosed transfer where practical.
- Provide local exhaust ventilation.
- Use low-dust or liquid grades where appropriate.
- Follow respiratory-protection requirements in the SDS.
- Avoid compressed-air cleaning.
- Use approved industrial vacuum equipment.
Microbiological quality and liquid-premix hygiene
Plant-derived raw materials and carrier-containing formulations require defined microbiological controls. Pure dry Thaumatin does not preserve an aqueous premix.
Supplier controls
- Botanical collection hygiene
- Raw-material cleaning
- Controlled extraction water
- Hygienic filtration and concentration
- Validated microbial-reduction process
- Post-process environmental control
- Drying and packaging hygiene
- Pathogen and indicator testing
Customer controls
- Use microbiologically suitable premix water.
- Prepare only the quantity required.
- Control liquid-premix temperature.
- Define maximum hold time.
- Validate any preservative system.
- Clean tanks, lines and dosing equipment.
- Prevent return of unused solution to the original package.
- Monitor finished-product shelf life.
Regulatory and labeling considerations
European Union
Thaumatin is identified as E 957. Its authorized function, permitted food categories, maximum levels or quantum-satis conditions and label declaration must be checked in the current European Union food-additive legislation.
- Regulation (EC) No 1333/2008 — authorized food-additive uses
- Commission Regulation (EU) No 231/2012 — food-additive specifications
A permitted use as a sweetener in one food category does not automatically authorize use as a flavor enhancer in another.
JECFA and Codex references
International buyers should consult the current JECFA specification and the Codex General Standard for Food Additives for the latest identity, purity, functional-class and category provisions.
United States
U.S. use should be supported by the supplier's exact legal basis, intended technical function and conditions of use. A European sweetener authorization or E number should not be treated as a U.S. authorization.
- Request the exact GRAS, FEMA or other regulatory basis.
- Confirm the permitted function and food categories.
- Confirm the maximum intended level.
- Confirm the required ingredient or flavor declaration.
- Confirm whether the source and production method match the cited basis.
Reference: U.S. FDA GRAS Notice Inventory
Other destination markets
- Confirm the recognized additive or flavor identity.
- Confirm whether the function is sweetener, flavor modifier or flavoring.
- Confirm the permitted food category.
- Confirm the maximum level or GMP condition.
- Confirm botanical-source and production-route requirements.
- Confirm ingredient-list wording.
- Confirm allergen, GMO and natural-claim requirements.
- Confirm import registration and certificate requirements.

Frequently asked questions
What is Thaumatin?
Thaumatin is an intensely sweet protein preparation traditionally extracted from the arils surrounding the seeds of Thaumatococcus daniellii fruit. Its food-additive identity is E 957 or INS 957.
Is Thaumatin a polyol?
No. It is a protein-based high-intensity sweetener and flavor modifier. It does not provide polyol bulk, humectancy or freezing-point effects.
How sweet is Thaumatin?
It is often described as several thousand times sweeter than sucrose by weight, but the ratio varies with dose, matrix and sensory method.
Does Thaumatin taste exactly like sugar?
No. It normally has slower onset and longer persistence. Excess use can create a lingering or licorice-like aftertaste.
Can it replace all the sugar in a product?
It can replace sweetness but not sugar's bulk, texture, browning, preservation, fermentation and freezing-point functions.
Is Thaumatin soluble in water?
Yes. It is water soluble, although dissolution and stability depend on grade, pH, salts, alcohol and other ingredients.
Is Thaumatin heat stable?
It can retain useful sweetness through selected heat processes, particularly in acidic systems. Prolonged severe heating can still denature the protein.
Can it mask bitterness?
It is frequently evaluated for bitterness masking and flavor modification, but the result depends on the bitter compound and full formulation.
Can it be combined with stevia?
Yes. Thaumatin may modify bitterness and sweetness persistence, but the combination can also create excessive lingering if poorly balanced.
Can it be combined with polyols?
Yes. Polyols can provide bulk while Thaumatin adds sweetness and flavor modification. Cooling effect and digestive-tolerance labeling still require evaluation.
Why is a premix recommended?
The required dose can be extremely low. A standardized dry premix or liquid concentrate improves weighing accuracy and batch uniformity.
Can Thaumatin be added directly to a beverage?
It can be dissolved in water, but pH, heat, polyphenols, minerals, clarity and premix holding time should be validated.
Can tea or botanical extracts affect it?
Tannins and polyphenols can interact with proteins and may cause haze, precipitation or changes in flavor performance.
Does Thaumatin provide calories?
It is a protein, but its caloric contribution is normally negligible because the ingredient is used at very low levels. Label claims must follow local rules.
Is Thaumatin allergen-free?
A universal allergen-free statement should not be assumed. Review its protein source, carrier, manufacturing facility and destination-market requirements.
Why is dust control important?
Fine protein dust may pose an occupational inhalation or sensitization risk. Follow the supplier SDS and use appropriate engineering controls.
Which COA values should buyers compare?
Review identity, active or protein assay, moisture, ash, pH, solubility, microbiology, elemental impurities and any application-specific sensory test.
Can Global Food Additives compare an existing grade?
Yes. Buyers can provide a specification, COA, approved sample, formulation, sensory target or competitor grade for technical and commercial comparison.
