Research by running, craig, and mattes (2015) suggests that there may be a sixth basic taste, "oleogustus", which is distinct from the five primary taste sensations

Researchers say they have separated the capacity of the human sense of taste to recognize fat as an unmistakable taste from  sweet, salty, bitter, sour and umami.

The essence of fat may join sweet, salty, bitter, sour and umami as an official feeling of the human sense of taste after researchers said they discovered individuals have a particular and fundamental capacity to identify it.  

Yet, it's no place close as delectable as it may appear, either in name or nature – they propose calling the new taste oleogustus, after Latin for fat taste, and say that in its crude shape it makes individuals gag.
