Stachyose
Stachyose is a tetrasaccharide of the raffinose family, composed of two galactose units, one glucose unit, and one fructose unit linked α-1,6 and α,β-1,2.
It occurs naturally in legumes, particularly soybeans, lupins, and Stachys tubers, which give the molecule its name.
Stachyose is non-digestible in the human small intestine and reaches the colon intact, where it is fermented by gut bacteria to short-chain fatty acids. This makes it a recognised prebiotic that selectively stimulates bifidobacteria and lactobacilli.
We source bulk Stachyose from top China manufacturers for our partners. The manufacturers are in Hebei and Shandong. 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
Stachyose is produced mainly as a high-purity dietary supplement ingredient and as part of soybean oligosaccharide concentrates.
Pure stachyose grade typically declares 70 to 95 percent stachyose with the balance being raffinose, verbascose, and minor sugars. It is a white to off-white powder.
Soybean oligosaccharide grade is a less refined product declaring around 70 percent oligosaccharides (stachyose plus raffinose) and is used as a bulk prebiotic.
Pharmaceutical-style grade exists for clinical trial and infant nutrition research use, with tighter limits on residual protein and lectin.

How We Help Source Stachyose
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 Stachyose 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 Stachyose together with other ingredients such as Fructooligosaccharides, Dextrose and Dextrose Monohydrate into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Stachyose is treated as a food ingredient or dietary supplement ingredient in most major markets, with no specific E number.
The U.S. FDA accepts it as a self-affirmed GRAS ingredient based on its long history of consumption in legumes.
Japan recognises soybean oligosaccharides (containing stachyose and raffinose) under the Foods for Specified Health Use framework with approved gut-health claims.
China lists stachyose as a permitted novel food ingredient with defined intake limits.
Manufacturing Process
Stachyose is recovered from soybean whey, a coproduct of soy protein concentrate manufacture.
Defatted soybean meal is extracted with aqueous ethanol to dissolve the soluble oligosaccharides. The extract is concentrated and decolorised.
The crude oligosaccharide solution is fractionated by chromatography on a calcium-form ion-exchange resin to separate stachyose from raffinose, verbascose, sucrose, and minor sugars.
The stachyose-enriched fraction is decolorised, demineralized, concentrated, and either spray-dried or crystallised.
An alternative source is Stachys tubers (Chinese artichoke), where stachyose is the dominant storage carbohydrate and can be extracted with water and purified by similar means.
