I didn't know that

Do you know what are the basic tastes that our tongue can recognize? As far as I knew there were only 4: bitterness, saltiness, sourness, and sweetness. But did you know there was a fifth basic taste. It's umami or savoryness. Umami is the name for the taste sensation produced by compounds such as glutamate, and are commonly found in fermented and aged foods. In English, it is also described as "meatiness", "relish", or "savoriness". The term comes from the Japanese word 'umai' for yummy, keen, or nice. Apparently, humans have taste receptors for the detection of amino acids (which are the building blocks of protein). So yea...now you know!
