Description

Calcium Glutamate is a calcium salt of the amino acid glutamic acid, serving as a vital source of both bioavailable calcium and flavor-enhancing glutamate. This dual functionality makes it a valuable ingredient for applications where nutritional fortification and taste modulation are required simultaneously. It is primarily utilized by manufacturers in the food and nutraceutical industries seeking to enhance product profiles.

Application

• Food Additive & Flavor Enhancer: Used as a source of umami taste and a calcium supplement in processed foods, soups, sauces, and seasonings.
• Nutraceutical & Dietary Supplements: Incorporated into calcium supplement formulations and functional foods for bone health support.
• Pharmaceutical Excipient: Acts as a stabilizer, flavor masker, or source of calcium in certain medicinal preparations and tablets.
• Animal Feed Supplement: Utilized in feed premixes to provide essential calcium and potentially improve palatability for livestock and poultry.
• Biochemical Research: Employed as a reagent or buffer component in various laboratory and microbiological culture media.
