What Is FOS Powder?
Fructooligosaccharides, abbreviated as FOS, are short-chain carbohydrates consisting mainly of fructose units.
FOS is used in food and nutrition formulations where manufacturers want to add a soluble prebiotic fiber component without significantly changing the basic format of the product.
From a formulation perspective, FOS offers several practical characteristics:
Water solubility
Mild sweetness
Powder form for dry blending
Compatibility with a range of nutrition ingredients
Use in both food and dietary supplement formats
The appropriate amount depends on the finished product, serving size, formulation design, and applicable regulations.

FOS 95% for Supplement Formulation
For B2B buyers, the 95% specification provides a defined basis for raw-material selection and formulation calculations.
FOS powder can be considered for:
Prebiotic powder blends
Fiber supplements
Nutrition powders
Capsule formulations
Tablet formulations
Sachets and stick packs
Functional drink mixes
Synbiotic formulas
Before a production order, R&D teams can evaluate the sample for taste, solubility, blending performance, and compatibility with other ingredients.

FOS Powder Applications
Dietary Supplements
FOS is used as a functional ingredient in fiber and prebiotic products. It can be incorporated into single-ingredient products or combined with other nutritional ingredients.
Nutrition Powders
The powder format makes FOS convenient for dry formulations such as sachets, drink mixes, and powdered nutrition products.
Functional Beverages
Because FOS dissolves in water, it can be considered for powdered beverage mixes and other liquid nutrition applications.
Functional Foods
Potential formats include nutrition bars, dairy-based products, dairy alternatives, and other food products formulated with added fiber.

Quality Control for Bulk FOS
When purchasing FOS on a commercial scale, the specification should be established before the order is placed.
Relevant quality checks may include:
FOS content
Confirms the active specification of the supplied material.
Moisture
Important for powder stability, storage, and handling.
Microbiological testing
Used to evaluate compliance with agreed microbiological limits.
Heavy metals and contaminants
Testing can be arranged according to the applicable product specification and destination-market requirements.
Appearance
The finished powder is checked against the agreed physical specification.
For commercial orders, the corresponding COA can be supplied for batch review.
Documentation for Supplier Evaluation
FOS buyers may require different documents during qualification and purchasing.
Gold Herb can provide applicable technical documentation, including:
Certificate of Analysis (COA)
Product Specification
Technical Data Sheet (TDS)
Safety Data Sheet (SDS)
Additional documentation should be confirmed according to the customer's market and project requirements.

Bulk Fructooligosaccharides Powder Supply
Commercial purchasing is normally based on more than the ingredient name.
When requesting a quotation, buyers can specify:
FOS percentage
Estimated order quantity
Packaging requirement
Destination country
Application
Required documentation
Sample requirement
This information allows the specification and quotation to be matched to the actual project rather than using a generic product offer.
For repeat purchases, keeping the same agreed specification and packaging format can also make raw-material management easier.
FOS Powder vs. Other Prebiotic Ingredients
FOS and other prebiotic ingredients are not interchangeable in every formulation.
The selection may depend on:
| Consideration | FOS Powder |
|---|---|
| Ingredient type | Fructooligosaccharides |
| Form | Powder |
| Solubility | Good water solubility |
| Taste | Mild sweetness |
| Main formulation role | Prebiotic / soluble fiber ingredient |
| Common formats | Powders, beverages, supplements, functional foods |
For a new product, the best ingredient should be selected according to the target formulation rather than simply comparing the headline percentage.
Storage & Handling
Keep FOS powder in a sealed package and store it in a cool, dry environment away from excessive moisture and direct sunlight.
After opening, reseal the package properly to limit moisture exposure.
The stated shelf life is 24 months when stored under recommended conditions.

Dietary supplement manufacturers
Functional food manufacturers
Nutrition brands
Ingredient distributors
Formulation and R&D projects
Before shipment, the order specification can be confirmed with the customer so that the required product grade, packaging, and documentation are clear.
