Glutamate flavoring

Glutamate flavoring uses glutamate, commonly monosodium glutamate (MSG), to intensify savory taste. It enhances umami, a taste also produced by naturally occurring glutamate in foods.

Umami: Umami is the savory taste associated with glutamate and some other compounds. Glutamate flavoring works by strengthening this basic taste.
Kikunae Ikeda: Kikunae Ikeda was a Japanese chemist who identified glutamate as a source of savory taste. His research established glutamate as the basis of kombu’s distinctive taste.
Food additive: A food additive is a substance deliberately added to food for a technological or sensory purpose. Glutamate is added to enhance flavor rather than provide a primary nutrient.
Sodium chloride: Sodium chloride is the chemical compound commonly known as table salt. Salt mainly produces salty taste, while glutamate enhances savory taste.
MSG symptom complex: MSG symptom complex is a name for short-lived symptoms reported after consuming foods containing MSG. Reports of these symptoms shaped public discussion of glutamate flavoring.
Glutamate receptor: A glutamate receptor is a protein that detects glutamate by binding to it. Taste-cell receptors detect glutamate and help produce umami perception.
Kombu: Kombu is an edible kelp widely used in Japanese cooking and broth-making. Ikeda studied its glutamate-rich broth while investigating savory taste.
Seasoning: Seasoning is the addition of ingredients that alter or strengthen a food’s flavor. MSG is used as a seasoning in home and commercial cooking.
Salt substitute: A salt substitute is an ingredient used to reduce or replace sodium chloride in food. Glutamate can add savory intensity but does not reproduce salt’s taste.
Food labeling: Food labeling is the presentation of ingredient, nutrition, and other required information on food packaging. Ingredient rules determine how added MSG and glutamate-containing ingredients appear on labels.
