글루탐산나트륨 (MSG) (MSG) is the sodium salt of glutamic acid, one of the most abundant naturally occurring amino acids found in foods such as tomatoes, parmesan cheese, and soy sauce. Commercially, MSG is produced through bacterial fermentation of carbohydrate feedstocks such as sugarcane or corn starch.
It delivers a clean, pure umami taste that enhances and deepens savory flavors while allowing manufacturers to reduce sodium chloride content by up to 30-40% without sacrificing palatability. MSG is supplied as uniform white crystals that dissolve readily in water and perform consistently across diverse food systems. It has been extensively studied and affirmed as safe by major food safety authorities worldwide.
