General Description

L-Glutamic Acid Monopotassium Salt is a chemical compound that is derived from L-glutamic acid, a commonly found amino acid, combined with a single potassium atom. This salt form is often used in research and various biochemical applications, given its role as a key molecule in cellular metabolism. Additionally, it is considered a popular food additive because it provides umami, the savory taste from foods such as meats and mushrooms, and is usually used to intensify these flavors. Also, L-glutamic acid is essential in the human body since it enables metabolic processes for the neurotransmitters, helping maintain proper brain function. L-GLUTAMIC ACID MONOPOTASSIUM SALT is generally considered safe, but large quantities might lead to minor side effects, such as headaches and digestive upset.

Method for preparing L-glutamic acid chelated potassium monohydrate

The invention discloses a method for preparing L-glutamic acid chelated potassium monohydrate. The method comprises the following steps of performing a reaction by using potassium carbonate or potassium hydroxide, and L-glutamic acid as raw materials, and by using water of which the temperature is 70-80 DEG C as a solvent, clarifying a solution, adjusting the pH value of reaction liquid to 7.5-8.5, continuing a reaction at 80-85 DEG C for 2-4 hours, decoloring reaction liquid, performing filtration, performing concentration to a Baume degree of 36-38 degree Be, and then performing cooling to 15-20 DEG C; and adding L-glutamic acid chelated potassium monohydrate crystals as seed crystals to concentrated liquid, maintaining the temperature to be 15-20 DEG C, performing stirring for crystallization, performing discharging, performing centrifugation so as to obtain crude products, rinsing every 100 kg of the crude products with 5-10 L of deionized water, and drying solids so as to obtain products of which the chelating degree is 95% or above. According to the method disclosed by the invention, an organic solvent is not used, so that the safety coefficient of production environment is increased, and the cost of the raw materials is substantially reduced; the products are free from solvent residues, and moisture is easy to control; and besides, investment on equipment and sites can be reduced.
