Description

L-Glutamic Acid Monopotassium Salt is a high-purity, water-soluble salt of glutamic acid, serving as a key source of the umami flavor and a vital biochemical intermediate. This compound is valued for its stability and compatibility in formulations requiring precise pH control and flavor enhancement. It is essential for manufacturers in the food, pharmaceutical, and biotechnology sectors seeking reliable, high-quality ingredients for nutritional supplements, flavor potentiators, and cell culture media.

Application

• Flavor Potentiator & Seasoning Agent: A primary component in monosodium glutamate (MSG) alternatives and low-sodium seasoning blends to enhance savory umami taste profiles.
• Pharmaceutical Excipient & Nutrient: Used in parenteral nutrition solutions, electrolyte replenishers, and as a buffering agent in various medicinal formulations.
• Cell Culture & Fermentation Media: Serves as a critical nitrogen source and growth factor in microbial fermentation processes and mammalian cell culture applications.
• Dietary Supplement & Sports Nutrition: Incorporated into amino acid supplements, protein powders, and recovery drinks for its role in protein synthesis and neurotransmitter function.
• Biochemical Research & Diagnostic Reagents: Utilized as a standard or substrate in enzymatic assays, clinical diagnostics, and life science research.
• Cosmetic & Personal Care Formulations: Acts as a skin-conditioning agent and pH adjuster in creams, lotions, and hair care products.
