Potassium Malate

Potassium malate is the potassium salt of malic acid, a dicarboxylic acid that occurs naturally in fruit such as apples. Nustras supplies it as a white crystalline powder, used as a source of the mineral potassium in dietary supplements and as the food additive E351, an acidity regulator, in food and beverage manufacture.

It is formulated into mineral and electrolyte tablets, capsules and powders, sports and electrolyte beverages, functional foods and nutrient premixes. In food processing it is used as an acidity regulator and as a potassium salt in sodium-reduced products.

The material is a white crystalline powder, freely soluble in water; CAS 585-09-1, molecular formula C4H4K2O5, molecular weight 210.27. Content is standardised to specification, with identity confirmed by tests for potassium and malate and assay by titration or ICP. Heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies potassium malate in bulk commercial quantities, in sealed moisture-barrier packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Potassium malate is a permitted food additive and potassium source in major food and supplement markets; buyers confirm the elemental-potassium contribution, grade and permitted level for their application.
