Probiotics powder is not one ingredient. It is a material system: viable microbial strains, a carrier such as maltodextrin, and often a protective encapsulation layer. A different product category, postbiotic powder, replaces live cells with heat-inactivated biomass or postbiotic lysate. Understanding which materials are present — and why — is the first step in evaluating any probiotics powder specification.

This explainer breaks down the core composition of live probiotics powder, the role of carriers and the VPro® 5-layer micro-encapsulation material, and the alternative postbiotic forms represented by heat-inactivated Postbiotics Powder and ProLipo® Postbiotics. It uses named strains from the Shanghai Unibio Lab Co., Ltd portfolio — Bifidobacterium longum CCFM1195, Lactobacillus rhamnosus GG, and Lactobacillus plantarum HP59 — as concrete examples. Shanghai Unibio Lab Co., Ltd is a probiotic R&D, manufacturing, and CDMO enterprise based in Shanghai, China, founded in 2021.

Why Composition Matters Before You Compare Suppliers

The phrase "probiotics powder" is used across live cultures, heat-inactivated biomass, and blended formulations. On a specification sheet, a CFU figure alone does not tell a buyer which of these material systems is being offered. That ambiguity creates three practical problems.

First, live probiotics and postbiotics carry different storage, stability, and labeling implications. A powder that contains no live cells cannot support a viable-count claim at end of shelf life. Second, carriers are frequently listed without explaining their function, which makes it hard to judge whether the CFU figure has been standardized using a food-grade diluent or left as a concentrated culture. Third, encapsulation systems are often described with proprietary terms rather than with the actual material composition, which limits technical comparison.

Composition literacy changes the questions a buyer asks: Is the powder live or inactivated? Which strain, at which viable count, in which carrier? Is a protective coating applied, and what is it made of? Is the storage condition compatible with the intended distribution channel? These questions sit upstream of supplier selection and are answered by the material list, not by marketing language.

Industry Background: The Powder Format in Context

The global probiotics market was valued at USD 76.59 billion in 2025 and is projected to reach USD 114.95 billion by 2030, according to MarketsandMarkets (SRC-0001). The bacterial probiotics segment accounts for the largest share of that market (SRC-0001). Within application-specific segments, dry formats are dominant: in the animal feed probiotics market, the dry segment held an 84.7% revenue share in 2023 (SRC-0003).

The powder format's advantage is practical. Dry material is easier to store, transport, blend, and dose than liquid cultures. That advantage comes with a compositional cost: viable cells are sensitive to moisture, oxygen, heat, and gastric fluid, so the powder has to be engineered around those sensitivities.

Two guidance documents frame the manufacturing and labeling context. The International Probiotics Association manufacturing guideline recommends keeping probiotic dosage-form manufacturing below 25°C and below 60% relative humidity, with tighter refrigerated conditions if the delay between blending and dosage manufacturing exceeds 48 hours (SRC-0007). ISAPP's label guidance states that a probiotic product label should identify genus, species, strain designation, viable count at end of shelf life, and storage conditions (SRC-0005).

Those two documents point to the same conclusion: composition transparency is a technical requirement, not a marketing preference. A powder that does not disclose its strain identity, carrier, and viable-count basis is harder to verify and harder to formulate with.

What Probiotics Powder Is Made Of: Four Core Components

A live probiotics raw powder is built from four functional components. Each one can be described in material terms.

1. Live Probiotic Strains

The microbial component is the reason the product exists. Strains are identified at genus, species, and strain level, and the strain designation is what connects a powder to its supporting evidence.

Three examples illustrate how strain identity translates into a specification:

• Bifidobacterium longum CCFM1195 — viable count 10B–200B CFU/g; storage in a well-closed container away from moisture and direct sunlight at room temperature; shelf life 24 months under recommended storage; strain origin independent lab culture; listed for food & beverage, dietary supplement, and health product applications.
• Lactobacillus rhamnosus GG — viable count 10B–300B CFU/g; storage in a sealed package at -18°C or below; shelf life 24 months under recommended storage; strain origin independent lab culture; listed for food & beverage, dietary supplement, health product, and infant food.
• Lactobacillus plantarum HP59 — viable count 10B–200B CFU/g; storage at 2°C–8°C sealed cold storage; shelf life 24 months under recommended storage; strain origin independent lab culture; listed for food & beverage, dietary supplement, and fermented food.

The three examples also show that "room-temperature stable" is a strain-specific property, not a category-wide one. CCFM1195 is specified for room-temperature storage, GG for -18°C or below, and HP59 for 2°C–8°C. A buyer comparing powders without checking the storage line is comparing incomplete specifications.

2. Carriers Such as Maltodextrin

The carrier is the second material in the powder. In the Shanghai Unibio Lab product specifications, maltodextrin appears consistently as the carrier for both live probiotic raw powders and heat-inactivated postbiotic powder.

A carrier performs four functions in a powder system:

1. Dilution and standardization. A concentrated fermentation or freeze-dried culture is blended down to a target viable count per gram. The carrier makes a 10B CFU/g or 200B CFU/g specification reproducible.
2. Moisture management. A food-grade carrier reduces moisture migration within the powder matrix and helps protect viable cells during storage.
3. Flow and handling. Carrier-blended powders flow more consistently through filling, blending, and dosing equipment.
4. Blend consistency. In multi-strain formulas, the carrier provides a common base that helps distribute each strain evenly.

Carrier selection is not a neutral detail. The carrier type and ratio determine how much of the powder mass is active material versus diluent, and therefore how the CFU specification translates into a finished dose.

3. VPro® 5-Layer Micro-Encapsulation Material

Encapsulation is the third component in a protected live probiotics powder. Shanghai Unibio Lab's VPro® technology applies five functional layers to the strain:

1. Micromolecular protective layer — anti-freezing and anti-stress protection during freeze-drying and handling.
2. Prebiotic nutrition layer — supports in-vivo proliferation after ingestion.
3. Liposome enteric adhesion layer — supports intestinal colonization.
4. Acid and enzyme resistant layer — helps the strain survive gastric digestion.
5. Oxygen and moisture barrier layer — extends shelf stability.

In material terms, the VPro®-5L-COAT coating is described as a food-grade polysaccharide and protein composite coating matrix. The company reports that the technology lifts the freeze-drying survival rate by 40% and extends shelf life to 24 months. Those are company-reported performance figures and should be confirmed against batch-level data during qualification.

The reason encapsulation matters is mechanical. A bare freeze-dried cell has limited protection against acid, bile, oxygen, and moisture. The coating adds a physical barrier, but it also adds mass and process complexity. The trade-off is explicit: better survival and shelf stability in exchange for a more involved manufacturing step.

4. Postbiotic Forms: Heat-Inactivated Powder and ProLipo®

The fourth component category is not an additive to live probiotics powder but a different product form. Two postbiotic materials illustrate the distinction.

The structural difference is the wall material. Heat-inactivated Postbiotics Powder uses inactivated biomass plus maltodextrin. ProLipo® Postbiotics uses postbiotic lysate enclosed in a phospholipid liposome wall with a food-grade carrier. Both contain no live cells, which means neither supports a viable-count claim; their specifications are expressed in terms of active postbiotic content rather than CFU.

From Strain to Finished Powder: A Step-by-Step Breakdown

The composition list becomes clearer when mapped to the production sequence. For a live microencapsulated powder, the typical order is:

1. Strain selection. A strain with documented identity, origin, and application fit is chosen. Strain-level designation is the anchor for later claims.
2. Fermentation. The strain is cultured under controlled conditions. Shanghai Unibio Lab reports fermentation density above 3.5×10¹⁰ CFU/mL and lyophilized powder concentration up to 8.0×10¹¹ CFU/g under its process conditions.
3. Concentration and biomass separation. Cells are separated from the fermentation medium using equipment such as aseptic disc centrifuges.
4. Freeze-drying. Viable cells are stabilized by low-temperature vacuum drying.
5. Encapsulation. The VPro® 5-layer coating is applied where the specification calls for it.
6. Carrier blending. The concentrated material is blended with maltodextrin to reach the target CFU/g.
7. Quality testing. In-house viable count, microbial safety, and heavy metal testing are performed. Third-party inspection by SGS or Intertek can be requested.
8. Packaging. The powder is filled into moisture-barrier packaging for storage and shipment.

Each step changes the material that ends up in the bag. A buyer reading a specification is reading the output of this sequence, which is why the carrier line and the storage line are as informative as the CFU line.

How CFU/g Viability Ranges Are Expressed

Colony-forming units per gram (CFU/g) is the standard expression of viable count in a live probiotics powder. The range matters because the same strain can be supplied at different concentrations, and the chosen concentration affects dosage, cost, and stability.

Within the Shanghai Unibio Lab portfolio, common ranges include:

• 10B–200B CFU/g for many single strains, including Bifidobacterium longum CCFM1195 and Lactobacillus plantarum HP59.
• 10B–300B CFU/g for Lactobacillus rhamnosus GG and Bacillus coagulans CCFM1041 (-39).
• 10B–600B CFU/g for Bifidobacterium animalis subsp. lactis BL03.
• 10B CFU/g for Clostridium Butyricum CCFM1299.

Three conventions matter when reading these figures. First, the count should be tied to a defined point in the product lifecycle. ISAPP guidance recommends stating viable count at end of shelf life rather than only at production (SRC-0005). Second, the storage condition should be stated alongside the count, because a 200B CFU/g powder stored at -18°C and a 200B CFU/g powder stored at room temperature do not carry the same stability risk. Third, the CFU figure is not the same as total cell count; some specifications, such as Lactobacillus rhamnosus CCFM1219, are expressed as total cell count (10B–200B cells/g) rather than CFU/g.

A fourth convention is labeling. ISAPP guidance lists genus, species, strain designation, viable count at end of shelf life, and storage conditions as the core label elements (SRC-0005). A specification that omits the strain designation or the end-of-shelf-life basis is harder to verify against the label.

When to Choose Live Probiotics vs Postbiotics

The choice between live probiotics powder and postbiotic powder is a formulation decision, not a quality hierarchy. Each form has a defined role.

Live probiotics powder is the appropriate choice when:

• The finished product needs viable cells at the point of consumption, and the label will carry a CFU claim.
• The target application has strain-specific evidence that depends on live cells.
• Storage and distribution can maintain the required condition — room temperature for a strain like CCFM1195, -18°C or below for GG, or 2°C–8°C for HP59.

Postbiotic powder is the appropriate choice when:

• The formulation or distribution channel cannot reliably maintain live-cell viability.
• The product concept is built around non-viable postbiotic material rather than a CFU claim.
• The application calls for the specific material system — inactivated biomass plus maltodextrin for Postbiotics Powder, or postbiotic lysate in a phospholipid liposome wall for ProLipo® Postbiotics.

The main trade-off is straightforward. Live probiotics offer viable-cell functionality but carry tighter storage and handling requirements. Postbiotics remove the live-cell variable but do not support CFU claims. Encapsulation can narrow the gap for live strains, at the cost of an additional manufacturing step.

Frequently Asked Questions

Conclusion

Probiotics powder composition comes down to four material categories: live probiotic strains, a carrier such as maltodextrin, an encapsulation material such as the VPro® 5-layer coating, and — in the postbiotic form — inactivated biomass or postbiotic lysate with its own carrier and wall material. The strain provides the viable component; the carrier standardizes and stabilizes it; the coating protects it; the postbiotic route removes viable cells entirely.

For a buyer in the evaluation stage, the practical test is whether a specification answers five questions: which strain, at which viable count, in which carrier, with which protective material, and under which storage condition. A powder that answers all five is comparable. A powder that answers only the CFU question is not.
