Fructooligosaccharides

Fructooligosaccharides are the plural form of the prebiotic carbohydrate class commonly abbreviated FOS, covering a distribution of glucose-terminated short-chain fructans with two to nine fructose units linked by β-2,1 bonds.

The plural label is the form commonly used on ingredient declarations and in clinical literature, because commercial preparations are always mixtures of GF2, GF3, and GF4 species rather than a single pure compound.

The material is partly sweet, freely soluble, non-digestible by human small intestine enzymes, and selectively fermented by bifidobacteria and lactobacilli in the colon.

We source bulk Fructooligosaccharides from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Shandong, Guangdong and Shanghai. A smaller requirement can ship in a combined container with other ingredients.

Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades

Fructooligosaccharides are graded by purity, source, and physical form.

Standard commercial grade declares 95 percent FOS on a dry basis, sold as either spray-dried powder or 75 percent solids syrup.

Chromatographically separated grade declares 97 to 99 percent FOS for high-purity supplement and infant nutrition use.

Inulin-derived oligofructose grade is produced from chicory and carries a slightly wider DP distribution (DP 2 to 7) than sucrose-source FOS.

Organic and non-GMO certified grades exist from both chicory and sucrose sources.

Brand names, product names and logos are the property of their owners. They appear here as published evidence that the ingredient is used, taken from the brand's own label or website. Their appearance is not an endorsement, and it does not mean the brand buys from us or from any manufacturer listed on this site.

How We Help Source Fructooligosaccharides

Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Fructooligosaccharides out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Fructooligosaccharides together with other ingredients such as Dextrose, Dextrose Monohydrate and L-Arabinose into one 20' FCL. If your quantity is small, we can also ship LCL.

Regulatory Status

Fructooligosaccharides are recognised as a food ingredient and dietary fibre in most major markets, generally without an E number.

The U.S. FDA accepts FOS as a self-affirmed GRAS ingredient and lists short-chain FOS as a dietary fibre under the revised Nutrition Facts panel.

EFSA has reviewed FOS for infant nutrition. Japan recognises FOS under the Foods for Specified Health Use framework.

The Codex Alimentarius covers FOS within the general dietary fibre definition based on the AOAC analytical methods.

Manufacturing Process

Fructooligosaccharides Manufacturing Process

Loading process diagram…

Commercial fructooligosaccharides are produced by two parallel routes.

The sucrose-substrate route uses immobilized fructosyltransferase enzymes (commonly from Aspergillus or Aureobasidium) that transfer fructose units between sucrose molecules to build short-chain fructans.

The chicory-inulin route uses endo-inulinase to partially hydrolyse the long-chain inulin from chicory root into shorter oligofructose fragments.

Both reaction streams are purified through carbon treatment and ion exchange. Chromatographic polishing separates residual mono- and disaccharides for high-purity grades.

The final solutions are concentrated and dried into white free-flowing powders or kept as clear syrups for liquid dosing.
