Description

Monopotassium glutamate (CAS 19473-49-5 ), also known by its food additive designation E622 , is the potassium salt of glutamic acid used as a flavor enhancer in food manufacturing. It delivers umami taste reinforcement while offering a sodium-free alternative to monosodium glutamate for sodium-reduction formulations. In processed food manufacturing, it is used to enhance savory flavor profiles. This ingredient is commonly found in soups, sauces, seasonings, and snack coatings without contributing sodium load. Meat processors and ready-meal producers incorporate it into spice blends and marinades. It is ideal where umami depth is required alongside clean-label or reduced-sodium claims. In dietary and functional food formulations, it serves as a potassium source combined with flavor functionality. This ingredient supports dual-purpose ingredient strategies for modern food science. Pharmaceutical manufacturers use potassium glutamate as an excipient and electrolyte component in certain oral preparations. It is also utilized in parenteral preparations for specific healthcare needs. Monopotassium glutamate is supplied as a white crystalline powder, with the monohydrate form being the most commercially prevalent. Food-grade material conforming to FCC specifications is standard for food and flavoring applications. Pharmaceutical-grade material meeting USP or Ph.Eur. standards is available for healthcare use. These high-purity grades ensure safety and efficacy for parenteral use cases. The material is highly soluble and stable under standard processing conditions for various industrial applications.
