Beetroot powder

Beetroot powder suppliers and sourcing guide

Beetroot powder is red beet (Beta vulgaris) root that is washed, sliced or pureed, dried (air-dried, drum-dried or spray-dried) and milled. Its red-purple color comes from betalain pigments, which are sensitive to heat, light and oxygen. Brands use it for color in foods and cosmetics and as a vegetable ingredient in drink mixes and bars; beet juice powder, made by spray-drying juice with or without a carrier, is a finer, more soluble form.

Forms and grades of beetroot powder

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

  • Air-dried root powder

    Sliced root dried and milled, 100 percent beet, with some fiber and an earthy flavor.

  • Spray-dried juice powder

    Beet juice dried, often with maltodextrin, for soluble drink mixes and color use.

  • Color-standardized

    Powder or juice concentrate sold for coloring with a stated betanin or color value.

  • Organic

    Certified organic root and juice powders.

What to check on the COA

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

Color strength
Betanin content or color value by spectrophotometry (absorbance near 535 nm).
Moisture and volatile matter
Loss on drying, also the volatile matter limit in the color additive specification.
Acid-insoluble ash
A measure of soil and sand carried over from the roots.
Heavy metals
Lead, arsenic and mercury by ICP-MS, compared with the limits in 21 CFR 73.40.
Nitrate
Nitrate by ion chromatography or HPLC when the buyer's specification or label sets a level.
Microbiology
Total plate count, yeast and mold, coliforms or Enterobacteriaceae, E. coli and Salmonella; low-moisture foods that are eaten without a cooking step need a negative Salmonella result per lot.

Storage, lots and expiry

Storage and shelf life

Keep in sealed light- and moisture-barrier packaging in a cool, dry place; heat, light, oxygen and moisture all fade the betalain color. Shelf life is set by the supplier's specification, and older lots are retested for color value and moisture before use.

Lots and expiry dates

Color strength, nitrate and sugar vary with beet variety, harvest and drying method, so record color value per lot. Rotate first in, first out and match lots when color consistency matters.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.
