Taste First Identified by Japanese Chemist Kikunae Ikeda in 1908

The Discovery of Umami
In 1908, Japanese chemist Kikunae Ikeda made a groundbreaking discovery in the field of taste perception by identifying the fifth basic taste, which he named umami. Prior to this discovery, it was commonly believed that there were only four basic tastes: sweet, sour, salty, and bitter. Ikeda’s work revealed that umami was a distinct taste, fundamentally different from the other four.

What is Umami?
Umami, which translates to “savory” or “delicious” in Japanese, is a taste sensation typically associated with the flavor of glutamates. It is often described as a rich, brothy, or meaty taste. This taste is a fundamental component in the culinary world, influencing how food flavors are perceived and enjoyed.

  1. Umami in Foods
    Natural sources of umami include a variety of foods rich in glutamates and nucleotides:

    • Seaweed: Ikeda identified glutamic acid as the source of umami taste while studying the properties of kombu, a type of seaweed used in Japanese cuisine.
    • Fermented Foods: Foods such as soy sauce and fish sauce are high in umami.
    • Aged Products: Cheeses, like parmesan, are also rich in umami due to the aging process that concentrates glutamic acids.
    • Protein-Rich Foods: Meats and broths, especially those that have been cooked for long periods, release glutamates that enhance umami taste.
    • Vegetables: Tomatoes, mushrooms, and green tea also contribute to umami flavor due to naturally occurring glutamates.

  2. Physiology of Umami Perception
    The ability to perceive umami is universal and intrinsic to the human sense of taste. On a physiological level, umami is detected by specific taste receptors in the mouth known as metabotropic glutamate receptors (mGluRs) and T1R1 + T1R3 receptors, which respond to the presence of glutamates.

  3. Umami and Nutrition
    Umami plays an essential role in signaling the presence of proteins in food, which are crucial for survival. This makes umami not just a taste but a signal of nutritional value, encouraging the intake of protein-rich foods necessary for maintaining a healthy diet.

  4. Umami in Culinary Applications

    • Asian Cuisine: Umami is a vital taste element in Asian cuisines, particularly Japanese, Chinese, and Thai dishes.
    • Western Cuisine: Many chefs incorporate umami elements through ingredients like tomatoes, cheese, and broth reductions to enhance flavor profiles.
    • Flavor Enhancement: Umami is often used to reduce sodium content in foods while maintaining a satisfying taste experience, as it enhances and balances the overall flavor.

  5. Umami in Science and Food Industry
    The recognition of umami has had significant implications in both the scientific study of taste and the food industry:

    • Research: Ongoing studies continue to explore the role of umami in diet, nutrition, and the neurological mechanisms of taste.
    • Industry: The discovery led to the commercial production of monosodium glutamate (MSG), a flavor enhancer that mimics the natural umami taste.

  6. Criticism and Misunderstanding
    Despite its widespread use and acceptance, umami and MSG have sometimes been met with skepticism and criticism over health concerns, known as “Chinese restaurant syndrome.” However, extensive scientific research has largely debunked these myths, confirming the safety of MSG consumption for the general population.
