Larch arabinogalactan

Larch arabinogalactan suppliers and sourcing guide

Larch arabinogalactan is a water-soluble, highly branched polysaccharide made of galactose and arabinose units, extracted from the wood of larch trees. Wood chips of western larch (Larix occidentalis) or eastern larch (Larix laricina) are extracted with water, and the extract is filtered, purified, concentrated and spray-dried. Buyers get a fine, off-white to light tan powder with little taste that dissolves readily and gives solutions of low viscosity.

Forms and grades of larch arabinogalactan

Suppliers sell different products under the same name. Specify the one you need.

  • Spray-dried powder

    The standard form; fine powder that dissolves quickly in water and mixes into dry blends.

  • Agglomerated (instantized) powder

    Granulated grade that disperses with less clumping and dust in drink mixes.

  • Organic

    Made from larch wood under organic certification, offered by some producers.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Arabinogalactan content
Polysaccharide content by HPLC or size-exclusion chromatography, or calculated by difference, on a dry basis.
Sugar composition
Galactose and arabinose ratio by HPLC or GC after acid hydrolysis, which confirms identity.
Moisture and ash
Loss on drying and residue on ignition; the powder is hygroscopic.
Solution color and clarity
Color of a standard solution, which shows how well wood extractives were removed.
Heavy metals
Lead, arsenic, cadmium and mercury by ICP-MS.
Microbiology
Total plate count, yeast and mold, coliforms or Enterobacteriaceae, E. coli and Salmonella.

Storage, lots and expiry

Storage and shelf life

Arabinogalactan powder takes up moisture and can cake, so keep it in sealed, moisture-barrier bags or lined drums in a cool, dry place. Re-seal opened containers promptly. Shelf life is set by the supplier's best-before or retest date for unopened packaging.

Lots and expiry dates

Color, moisture and polysaccharide content can vary by lot, so compare them on each COA. Record the larch species and the producer, since the GRAS notices are specific to their notifiers' products.
