Researchers determine existence of 'fat' flavour

In a paper published in the latest issue of Flavour Journal, the researchers with Deakin's newly formed Centre of Advanced Sensory Science have detailed the evidence for fat taste from diverse fields of science including molecular biology, neurobiology and sensory science. They found there is overwhelming evidence for the tongue's ability to detect fat, making it the sixth taste alongside sweet, salt, sour, bitter and umami.

But of course.
