Umami is recognized as the fifth basic taste, alongside sweet, sour, salty, and bitter. It is often described as a savory flavor, primarily associated with foods high in glutamate, such as meats, cheeses, and broths. This taste plays a crucial role in enhancing the overall flavor profile of various dishes and is vital for detecting certain amino acids that are important for nutrition.

Umami was first identified as a distinct taste in the early 20th century by Japanese chemist Kikunae Ikeda when he isolated glutamate from seaweed.
The umami taste is detected by specific receptors on taste buds that respond to glutamate and other related compounds like inosinate and guanylate.
Foods that are naturally rich in umami include tomatoes, mushrooms, soy sauce, and aged cheeses, making them popular ingredients in many cuisines.
