What is umami? Deep dive into the fifth flavour

Sweet, salty, sour, bitter — everyone knows these flavour profiles. But did you know there is a fifth dimension to flavour that is often overlooked? We’re talking about the umami flavor. We’ll not only explain the science behind the umami taste, but also show you how to take your pantry to the next umami level with real high-protein and high-fiber heroes. Spoiler: Your taste buds will be amazed.

What is the umami flavour?

So what exactly is the umami flavor? Translated from Japanese, it roughly means “meaty,” “hearty,” or simply “delicious.” But what exactly does umami taste like? It’s not a localized sensation, like “sweet” on the tip of the tongue. Instead, the umami taste fills your mouth, lingers, and really gets your mouth watering. Imagine the savory depth of a long-simmered sauce or the intense character of fermented foods… mmm—that’s exactly what umami is! It’s that deep, full-bodied kick that makes you want a second (and third) spoonful right after the first.

Umami flavour sense: the science behind it

The science nerd in you might be curious: What triggers the umami taste? For a long time, classifying umami within the world of the five basic tastes was a culinary mystery. But today we know: The answer lies in chemistry, more specifically in the interaction between amino acids (the building blocks of proteins) and our taste receptors. Above all, the salts of glutamic acid, which occur naturally in high protein foods, trigger that typical umami “Mmm.” Your sense of umami acts as your internal compass: your palate recognizes the savory depth of your meal and rewards you with that characteristic, full-bodied aroma.

Real flavor doesn’t actually need any artificial shortcuts. Instead of tricking your taste buds with lab tricks, we at KoRo prioritize transparency. You can read exactly what we mean by that in our blog article on clean label.

Which foods are umami: our favourites – from high protein to rich in fibre

Want to know how to create umami flavor without spending hours searching or resorting to MSG? It’s simple: rely on the right ingredients straight from your pantry. Here are our umami favorites packed with protein and fiber. We call this the culinary “yum-win” situation.

  • Soy & mushrooms: When we talk about umami, there’s no getting around soy — after all, it’s the basis for classics like miso and soy sauce. Our organic soy strips literally soak up sauces and, as a base for your creations, provide a solid 52g of protein and 17g of fiber per 100 grams. Planning a burger night or barbecue? The vegan organic tofu and wakame burger combines soy and algae as sources of umami, while the vegane organic shiitake burger clearly shows why mushrooms are umami kings.

  • Tomatoes: Tomatoes are packed with natural glutamate—especially when they’re dried. Our sun dried tomatoes bring intense flavour to any dish. In the organic protein mix with tomato flakes this umami power is combined with high quality plant-based protein from soya beans and almonds. . 
  • Fermented foods: Fermentation is a real umami turbo. Products such as our vegan kimchi develop a complex, tangy-spicy aroma through the ripening process that instantly elevates any bowl. Our organic tempeh is also a real highlight: the fermented soybeans offer a nutty note and, with 18g of protein per 100 grams, are a source of protein.

The "umami spice": A Secret weapon

The truth is: You don’t need some synthetic miracle powder to take your dishes to the next level. While MSG is often linked to myths like “Chinese restaurant syndrome,” we prefer to rely on the natural depth of flavor found in food. Our personal holy grail of the umami spice experience? Without a doubt: nutritional yeast! It brings a cheesy aroma, protein, and fiber straight to your pasta or bowls—and it’s completely plant-based.

So what do we mean by all this? If you have the right basics in your cupboard, you can skip the culinary gimmicks. Umami isn’t just a fleeting food trend, but your body’s signal for pure enjoyment. Once you know how to combine this savory kick with protein- and fiber-rich ingredients, your cooking will become not only more flavorful but also smarter. Are you ready for the fifth flavour dimension? Your palate is already waiting for it.
