A butyrate-producing probiotic powder is a powdered dietary-supplement ingredient built around bacterial strains whose fermentation activity generates butyrate in the gut. Clostridium Butyricum CCFM1299 is a defined example of that ingredient class: a Clostridium butyricum strain supplied by Shanghai Unibio Lab Co., Ltd as a butyrate-producing probiotic raw powder with a viable count of 10B CFU/g, a 24-month shelf life under recommended storage, and a composition of probiotic strain, maltodextrin carrier, and VPro® 5-layer encapsulation material.

Production line at Shanghai Unibio Lab Co., Ltd, where butyrate-producing probiotic raw powders are fermented, freeze-dried and encapsulated.

This explainer answers a narrow set of questions that formulators, brand owners and procurement teams actually ask when they encounter the term: what the classification means, how Clostridium butyricum differs from the more familiar Lactobacillus and Bifidobacterium strains, what sits inside a CCFM1299 powder, and where the verified specifications end and the marketing language usually begins.

What “Butyrate-Producing” Means in a Probiotic Powder

Butyrate is a short-chain fatty acid (SCFA) formed when gut bacteria ferment dietary fibre and related substrates in the colon. It is generally recognised as a principal energy source for the epithelial cells lining the colon, and it sits alongside acetate and propionate as one of the three main SCFAs produced by the gut microbiota.

When a raw material is labelled a “butyrate-producing probiotic powder,” the term describes the metabolic behaviour of the strain inside the formula — its capacity to generate butyrate through fermentation — rather than a finished-product health claim. That distinction matters commercially: an ingredient can be correctly described as butyrate-producing while the claim on a finished retail pack is governed separately by the regulatory framework of the market where it is sold.

Why the strain name has to appear in full

Clostridium butyricum is a spore-forming, Gram-positive anaerobic bacterium and is a recognised butyrate producer. Because it forms spores, it behaves differently from many vegetative Lactobacillus and Bifidobacterium strains during blending, tabletting and storage — a difference that directly affects how a supplier should build the powder.

Genus and species alone, however, are not a specification. ISAPP guidance on reading a probiotic label states that a compliant product label should identify the genus, species and strain designation, the viable count at the end of shelf life, and the storage conditions; the same guidance notes that products disclosing a strain designation are more likely to have evidence behind them. On that basis, “Clostridium butyricum” is a category, while Clostridium Butyricum CCFM1299 is a specification.

Why This Ingredient Class Is Moving (Industry Background)

The commercial backdrop is large and still expanding. MarketsandMarkets reports the global probiotics market at USD 76.59 billion in 2025, projected to reach USD 114.95 billion by 2030, a compound annual growth rate of 8.5%. Within that market, the bacterial probiotics segment accounts for the largest share, driven by widespread use in dietary supplements.

Format matters as much as strain. In the animal feed segment — a useful proxy for how buyers treat stability — the dry form led with an 84.7% revenue share in 2023. Powder is the dominant delivery format precisely because dry material tolerates long-distance shipping and ambient retail conditions better than liquid cultures.

That preference creates a technical obligation for butyrate producers. Clostridium butyricum is anaerobic, and oxygen and moisture exposure during blending and storage are the practical constraints on viability. The International Probiotics Association manufacturing guideline recommends keeping dosage-form manufacturing below 25 °C and below 60% relative humidity where acceptable, and moving to tighter refrigerated conditions if the delay between blending and dosage manufacturing exceeds 48 hours. For an export-oriented raw powder, that guideline has to be engineered into the material itself — which is what encapsulation layers are for.

Clostridium Butyricum CCFM1299: Identity, Classification and Specifications

The product is classified by its manufacturer as a Clostridium butyricum butyrate-producing probiotic powder, positioned for dietary supplement, metabolic management and health product applications. Its declared specification is as follows.

Two points in that table deserve attention during evaluation. First, the declared viable count is 10B CFU/g — buyers should confirm in writing whether the quoted figure is measured at the point of manufacture or at the end of the 24-month shelf life, because ISAPP recommends label disclosure at end of shelf life. Second, the storage statement is room temperature, not frozen. That is a deliberate formulation choice, not a default, and it is the result of the encapsulation system described below.

What Is Actually Inside the Powder

The composition lists three components, and each does a distinct job.

1. The probiotic strain — CCFM1299

The active ingredient is the Clostridium butyricum CCFM1299 strain itself. In a spore-forming species, the viable unit delivered to the blender is the spore, which is one reason C. butyricum raw powders can be standardised into ambient-stable formats more readily than strictly vegetative strains.

2. The maltodextrin carrier

Maltodextrin acts as the carrier matrix. It provides bulk so that a high-potency concentrate can be standardised to a declared CFU per gram, keeps the powder free-flowing during blending and filling, and reduces localised moisture migration around the cells.

3. The VPro® 5-layer encapsulation material

The coating matrix is a food-grade polysaccharide and protein composite. It is the component that separates a plain freeze-dried culture from a powder engineered for ambient storage and gastric transit.

Blending and encapsulation area. Environmental control during blending is a decisive variable for anaerobic butyrate-producing strains.

How VPro® 5-Layer Microencapsulation Supports a Butyrate Producer

Shanghai Unibio Lab developed the VPro® five-layer embedding system to address four industrial failure points for probiotics: acid damage, bile damage, oxygen exposure, and freezing stress. Each layer has a defined function.

For a butyrate-producing powder specifically, the oxygen and moisture barrier layer carries the most commercial weight: anaerobic strains are the most sensitive to oxidative stress during transport and retail display. The acid and enzyme resistant layer addresses the other half of the problem — delivering the strain through the stomach so that it reaches the colon, where butyrate fermentation actually takes place.

The manufacturer reports the following process outcomes for the VPro® system:

• Freeze-drying survival rate lifted by 40%
• Shelf life extended to 24 months
• Fermentation density above 3.5×10¹⁰ CFU/mL
• Lyophilised powder concentration up to 8.0×10¹¹ CFU/g

Step-by-Step: From Strain Bank to Finished Butyrate-Producing Powder

Understanding the production sequence helps buyers identify which stage to question when a sample behaves unexpectedly. The manufacturer’s process runs as follows.

1. Strain selection and banking. CCFM1299 is drawn from a proprietary strain bank of more than 30,000 microbial strains. The strain originates from independent lab culture, and the single-strain identity is fixed at this stage — once the strain designation is agreed in the specification, it should not change between sample and bulk.
2. Fermentation. Production uses high-density ion-exchange culture combined with automatic feedback feeding and biofilm stabilisation techniques. This is the stage that determines cell density going into the freeze dryer, and it is where the reported fermentation density above 3.5×10¹⁰ CFU/mL is achieved.
3. Freeze-drying. The culture is lyophilised. For an anaerobic, spore-forming species this step is also a stress event, which is why the micromolecular protective layer is relevant here.
4. VPro® 5-layer encapsulation. The dried cells are coated with the food-grade polysaccharide and protein composite matrix described above.
5. Blending and standardisation. Encapsulated cells are blended with the maltodextrin carrier to reach the declared 10B CFU/g and a consistent particle size.
6. Quality control. Every batch is tested in-house for viable count, microbial safety and heavy metals. Third-party inspection by SGS or Intertek is available at the buyer’s request, and a batch quality report is issued with the shipment.
7. Dosage form and packaging. Depending on the project, the material ships as bulk raw powder or is further processed into powder sachets, capsules, tablets or gummies under the manufacturer’s OEM, ODM, private label or custom-formula services.

Use Cases: Where a Butyrate-Producing Powder Fits

Clostridium Butyricum CCFM1299 is declared for dietary supplement, metabolic management product and health product applications. In practice that translates into four recurring project types.

Adult gut-health lines and bowel-regulating formats

Because butyrate is a fermentation product of the colonic microbiota, the most direct application is in adult digestive and gut-health formulations — typically capsules or stick-pack powders, where the strain contributes a non-Lactobacillus, spore-forming component to an otherwise conventional blend.

Metabolic management positioning

The strain is classified by the manufacturer under metabolic management products. Brands building a metabolic or weight-management range often use a butyrate producer as the spore-forming anchor alongside other strains targeted at metabolic endpoints.

Multi-strain blends

A spore-forming strain can be combined with Lactobacillus and Bifidobacterium strains in a single powder. Compound-blend projects are supported by custom strain combination and formulation optimisation services, with a minimum order quantity of 5 kg for multi-strain compound powder.

Ambient-stable retail formats

Because the declared storage condition is room temperature with a 24-month shelf life, the powder suits retail channels where cold chain is impractical. That is the point of pairing it with VPro® encapsulation rather than selling a naked freeze-dried culture.

Regional fit matters too. The HALAL certification held by the manufacturer explicitly covers Clostridium Butyricum CCFM1299, which removes one of the most common documentation obstacles for supplement brands selling into Southeast Asia and the Middle East.

Comparison: CCFM1299 Alongside Other Probiotic Raw Powders

Butyrate-producing powder is one option inside a broader raw-material portfolio. The table below compares CCFM1299 with three other single-strain powders from the same manufacturer, using only declared product data.

The comparison is not a ranking. It shows where CCFM1299 sits technically: it is the only butyrate-producing, spore-forming Clostridium option in the group, and its declared concentration is fixed at 10B CFU/g rather than offered across a wide potency band. A brand needing a higher declared CFU per gram in the finished blend would typically increase the inclusion rate in the formula or ask the supplier whether a custom concentration can be produced, rather than assume the standard spec is adjustable.

Specification and Sourcing Checklist for Buyers

When evaluating any butyrate-producing probiotic powder, the same qualification logic applies. The points below are the ones that most often separate a compliant purchase from a costly resupply.

• Strain designation in writing. Confirm the full strain code (CCFM1299) on the specification sheet, the Certificate of Analysis and the commercial invoice — not only on the marketing page.
• End-of-shelf-life count. State in the purchase specification whether the declared viable count is at manufacture or at end of shelf life. ISAPP recommends end-of-shelf-life disclosure, and the gap between the two can be significant.
• Encapsulation on the CoA. If the material is priced as encapsulated, the coating should be identifiable in the product documentation. Confirm that the VPro® 5-layer encapsulation material is part of the delivered composition, not an optional extra.
• Batch-level safety testing. Viable count, microbial safety and heavy metals should be tested per batch. Third-party inspection by SGS or Intertek should be available on request.
• Storage validation for your route. Room-temperature stability is a claim that has to survive your warehouse, your co-packer and your distribution channel. Test the material under your own conditions before committing to a full run.
• Documentation pack for the destination market. Request the certificates relevant to the market of sale at quotation stage, not after the order is placed.
• Ask vendors for scientific support. The Council for Responsible Nutrition recommends asking suppliers for scientific support linking the specific strains, in their labelled amounts, to the benefits claimed. That question is as valid for a raw-material supplier as for a finished-goods vendor.

Frequently Asked Questions

Conclusion: Butyrate-Producing Powder Is a Specification, Not a Slogan

Butyrate-producing probiotic powder describes an ingredient class defined by metabolic output: strains whose fermentation activity generates butyrate in the colon. The category is commercially meaningful because dry powder dominates probiotic delivery, because buyers increasingly demand strain-level specification, and because anaerobic butyrate producers place unusual demands on encapsulation and storage.

Clostridium Butyricum CCFM1299 sits precisely at that intersection. It is a spore-forming Clostridium butyricum strain, declared at 10B CFU/g with a 24-month shelf life under room-temperature storage, built on probiotic strain, maltodextrin carrier and VPro® 5-layer encapsulation material, and classified for dietary supplement, metabolic management and health product applications. The verified facts stop there — and for a buyer, knowing exactly where the facts stop is what makes the specification usable.
