Potassium Chloride - Food Grade

INCI: Potassium Chloride

Potassium Chloride (KCl) is a white, odourless crystalline salt used as a sodium-free source of potassium. In formulation it is valued as a salt replacer for reduced-sodium foods, a potassium source in electrolyte and mineral blends, and a nutrient for brewing and feed applications.

Specification

• Chemical formula: KCl
• CAS No: 7447-40-7
• EC/EINECS: 231-211-8
• E number: E508
• Molecular weight: 74.55 g/mol
• Potassium content: approx. 52% by weight
• Appearance: white, free-flowing crystalline powder
• Solubility: approx. 34 g per 100 mL water at 20°C
• pH (5% solution): approx. 5.0–8.0

Formulation notes

• Has a salty taste with a slightly bitter or metallic edge at higher inclusion; it is commonly blended with sodium chloride and flavour maskers to balance this.
• Dissolves readily and is slightly endothermic on dissolving, so solutions cool as the powder goes in.
• Blends well with other mineral salts in dry mixes. For clear liquid stocks, make separate single-salt solutions and combine at final dilution.

Common uses

• Reduced-sodium food manufacture - partial replacement for sodium chloride in baked goods, sauces, soups, snacks and processed foods
• Electrolyte and sports drink powders - potassium source alongside sodium, magnesium and calcium salts
• Mineral and supplement blends - powder, capsule and tablet formulations
• Animal and equine feed supplements - potassium source in custom mineral mixes
• Home brewing and winemaking - brewing water mineral adjustment and yeast nutrient

Storage

Store in a cool, dry place in a sealed container. Potassium chloride can take up moisture from humid air and will cake if left open, so reseal the bag immediately after use.
