Spinach powder

Spinach powder suppliers and sourcing guide

Spinach powder is spinach (Spinacia oleracea) leaf that is washed, blanched or not, dried (air-dried, drum-dried or freeze-dried) and milled to a green powder. It is used to add green color and vegetable content to pasta, breads, smoothie and greens blends, sauces and snacks. Drying method and particle size set the shade of green and how easily the powder disperses.

What to check on the COA

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

Color and identity
Color by colorimeter or a visual match to a standard, with microscopy or sensory checks for identity.
Moisture
Loss on drying, kept low to slow browning and caking.
Heavy metals
Lead, cadmium and arsenic by ICP-MS; leafy greens can take up cadmium and lead from soil.
Nitrate
Nitrate by ion chromatography or HPLC, since spinach accumulates nitrate.
Microbiology
Total plate count, yeast and mold, coliforms, E. coli and Salmonella, and Listeria for some buyers; leafy greens are a known source of pathogens.
Pesticides
Multi-residue pesticide screen by GC-MS/MS and LC-MS/MS.
