Abstract: Taste is a sensation of the gustatory system . Taste sensation along with olfaction is carried out by the trigeminal nerve. Taste receptors are present in the taste buds .Human tongues have papillae mostly on the anterior two-third of the tongue . The taste cells present on the tongue are responsible for the perception of taste.Around 50 years of age taste sensation tends to disappear slowly .the study aims to find and analyse about the effect of age on taste perception.To undergo this review, articles from PUBMED and Google scholar were collected and many other articles were collected from the reference section of other articles.It is found that many factors are responsible for loss of taste sensation like reduction of taste buds , poor oral hygiene ,salivary flow, systemic diseases, smoking, and medication. After referring to many articles it is evident that perception of bitter taste is lost with age. From the current study it is evident that many techniques have been used to detect the taste perception in old age people and the most effective method was threshold perception.
