Oh, carbs, how we like you. From pasta and pizza to potatoes and polenta, much of the world can't get enough of them, and they form a rich variety of dishes that delight our taste buds. It's long been believed that we've only had the ability to register five main tastes on our tongue-- salty, sweet, sour, bitter, and the tasty "Umami"-- however a brand-new research study recommends that we may have a carb-based sixth.
Writing in the journal Chemical Senses, a team of researchers note that the 5 primary tastes miss out a major, carbohydrate-focused section of our diet. "Every culture has a significant source of intricate carb. The concept that we can't taste exactly what we're consuming doesn't make good sense," coordinating author Juyun Lim, an associate teacher of food science and technology at Oregon State University, told New Scientist.
The proposed new taste would be a "starchy" one. Starch is a complicated carbohydrate, one that takes the type of many little sugar particles connected to each other in a large chain. Our bodies have the ability to break down these long polymer chains into smaller sugar ones that our cells use for energy. Starch is, without a shadow of a doubt, vital for our survival, and Lim's team recommends we can taste it, too.
Previously, food researchers have actually presumed that we find the existence of starch when our mastication-accompanying, enzyme-filled saliva breaks the polymers down into sugars, which we sign up as sweet tastes. In order to check how accurate this concept was, a range of combined carb options were provided to volunteers to taste while observers asked them to explain what they were tasting.
As it turns out, a significant variety of them were able to explain something along the lines of a "starchy" flavor, which seemed to suggest they might pick up on the long-chain starches as well as the sugary products of the enzyme breakdown. Those from an Asian origins described it as rice-like, and Caucasians described they found a bread or pasta-like taste.
