Discovering Umami: The Fifth Taste in Cooking

RRegina September 2, 2023 11:21 AM

You've probably heard of the four basic tastes—sweet, sour, salty, and bitter. But did you know there's a fifth one that's just as important? It’s called umami, often described as the savory, meaty taste found in foods like cooked meat, cheese, and ripe tomatoes. This mysterious fifth taste has been long recognized in Asian cultures, and is now making its way into the culinary lexicon of cooks and gourmets across the globe. So, let's embark on a sensory journey to discover umami, shall we?

What is Umami?

Umami is a Japanese word that translates to 'pleasant savory taste' and was identified in 1908 by a Japanese scientist named Kikunae Ikeda. According to him, umami is a taste distinct from the traditional four tastes and is associated with a mouth-filling, savory, and complex flavor that deepens the taste of foods.

Ikeda discovered that the key component responsible for umami is an amino acid called glutamate, which is naturally present in many foods. Later, it was found that nucleotides like inosinate and guanylate also contribute to umami and increase the intensity when combined with glutamate.

Umami Flavor Profile

Unlike the sharpness of sour, the sweetness of sugar, the bitterness of coffee, or the saltiness of sea water, umami is a subtle taste. It's often described as a savory, broth-like, or meaty flavor. However, rather than being a standalone taste, umami works to enhance and deepen the flavor of other ingredients, creating a more satisfying and rounded taste.

Foods Rich in Umami

Umami is present in a wide range of foods and can be naturally occurring or developed through cooking and fermentation processes. Here are some of the most umami-rich foods:

  1. Seaweed
  2. Soy Sauce
  3. Aged cheeses like Parmesan
  4. Tomatoes
  5. Mushrooms
  6. Meat
  7. Fish
  8. Fermented foods like miso and kimchi

Cooking Techniques to Enhance Umami

Understanding umami can significantly elevate your cooking. Here are some techniques to enhance the umami flavor in your dishes:

  • Browning and Roasting: The Maillard reaction that occurs during roasting or browning can increase umami.

  • Fermentation: Fermented foods like soy sauce, kimchi, and miso are loaded with umami due to the breakdown of proteins into amino acids during fermentation.

  • Using Stocks and Broths: Stocks made from meat, fish, or vegetables are rich in umami. They can be used as a base for soups, sauces, and stews.

  • Adding Umami-rich ingredients: Adding ingredients like tomatoes, mushrooms, and cheese to your dishes can significantly boost their umami flavor.

Umami in International Cuisines

Umami is a universal taste and is present in various international cuisines. In Italy, umami is found in sundried tomatoes and aged parmesan used in their pasta. In the United States, the classic burger achieves its allure from the umami of the beef patty, cheese, and ketchup. In Japan, dashi, a seaweed and bonito flake broth, is a staple umami-rich ingredient used in many dishes.

Health Aspects of Umami

Umami not only enhances the flavor but also has several health benefits.

  1. Increases Saliva and Helps Digestion: Umami increases saliva production, which helps in digestion and absorption of nutrients.

  2. Enhances Satiety: Umami has been linked to satiety and a feeling of fullness, which can help in portion control and weight management.

  3. Improves Palatability for Elderly: With age, the sense of taste decreases. Umami can improve the palatability of meals for the elderly, making it easier for them to maintain a healthy diet.

The Science Behind Umami

Umami taste is perceived by the taste receptors on our tongue and palate. These receptors are sensitive to the amino acid glutamate and nucleotides inosinate and guanylate. When these compounds interact with our taste receptors, they signal our brain to register the umami taste.

So, next time you're in the kitchen, try to incorporate some umami-rich ingredients into your dishes. You'll be amazed at the depth of flavor you can achieve by harnessing the power of this fifth taste.
