The Fifth Taste: Discovering the Savory Benefits of Umami

When chef Auguste Escoffier invented veal stock, he gave the world much more than just another starter for soups and sauces. Neither sweet, sour, salty nor bitter, its earthy savoriness changed cuisine forever.

He gave us the fifth, but yet to be named taste, umami. A century later, umami led to scientific intrigue. Perplexed about the defining flavor of dashi, a traditional broth, Japanese scientist Kikunae Ikeda took to his lab. There he isolated the chemical compound and ground zero of the fifth taste - glutamate. He then mass-produced it as Ajinomoto or essence of taste. We know it as monosodium glutamate, abbreviated by those three scary letters MSG. Today, the term umami - translated as ‘pleasant savory taste’ - is both official and universal. With the discovery of glutamate in breast milk and receptors on the tongue and stomach, its scientific legitimacy is no longer questioned. Further, revered by foodies more than ever, umami-dedicated cookbooks and even restaurants highlight its overdue place in the spotlight.

So, if the concept of umami is well established, where does all the confusion and controversy over glutamate come from? Why is it demonized in some circles while revered in others? Likely, the answer lies in the difference between natural forms of glutamate versus the manufactured forms. How are they different?

  • First, glutamate is found in most living things. The amount of glutamate and the presence of a few other specific food chemicals determine a food's umami.
  • Second, as food is cooked, aged, fermented or dried, glutamate breaks down and becomes more concentrated.
  • Third, the glutamate found in whole foods is chemically the same as the glutamate in powdered MSG. However, mass production generates impurities, which may explain the undesirable side effects experienced by some people. In contrast, the glutamate in whole foods comes packed with fiber, slowing its metabolism.

As for the reverence, multifaceted umami enhances the other flavor siblings. It can boost salty and sweet as well as subdue bitter and sour. But, as a fifth taste, it also elevates food, providing richness and complexity while increasing satiety. Coating the tongue, it helps flavors linger. Health-supportive chefs embrace umami-rich foods as they bring a meaty and salty essence to vegan and or low sodium dishes. Umami even enhances digestion, stimulating saliva and digestive juices. Following is a partial list of umami-rich foods. If you are new to this concept, take notice of these items' 'umami-ness'. Play with them in the kitchen and you’ll see how just a small amount can transform a dish. You’ll thank Escoffier.
