PURAC’s calcium, potassium and magnesium salts have a very neutral flavor profile, which makes them extremely suitable for powder formulations. PURAC’s iron and zinc salts have a relatively neutral taste, with less metallic flavor impact on the formulation than most alternative iron and zinc salts. The impact of mineral lactates and gluconates on pH when the powder formulation is added to water or food products is relatively small compared to some alternative sources such as certain carbonates, citrates, sulphates, oxides and hydroxides.
