Umami may be defined as a pleasant savoury, meaty taste representative of the amino acid L-glutamate and 5’-ribonucleotides (Yamaguchi & Ninomiya, 2000).

Taste buds send information about the food to the brain. The brain then breaks down this information, recognising the nature of the taste, whether it is sweet, salty, sour, bitter or savoury. However, it is not this simple, a vital factor on our perception of taste is the sensitivity of smell. Smell is 20,000 times more sensitive than taste

within the taste buds are taste receptor cells. Children have more taste receptors than adults and the number of taste receptors declines with age. The taste receptor cells detect the five different types of tastes, sweet, sour, salty, bitter, and umami/savory [1]. Everybody's preference for sweet taste may be because sweet foods are able to provide a quick source of energy.

Our ability to taste begins at the taste receptors on the tongue. The tongue detects six different taste sensations, known respectively as sweet, salty, sour, bitter, piquancy (spicy), and umami (savory). As shown in the How Smell Works section of the site, upon detecting a smell the olfactory neurones in the upper part of the nose generate an impulse which is passed to the brain along the olfactory nerve.Smell and Memory: The sense of smell

The conscious mind is the small part of the iceberg above the surface. It's linked with thinking, analysing and taking decisions. The conscious mind is actively arranging and filtering
