Abstract:The “active perception” of mammalian taste system for food flavor, nutrition and poison has a positive significance to guarantee their survival. Mammals have five basic tastes, such as sweet, fresh, bitter, salty and sour. Recent researches have made great progress on human taste system along with the rapid development of microelectronics, molecular biology and other subjects. Tastant binding with gustatory receptor causes cell depolarization and release of neurotransmitters, which are accepted by nerve fibers to generate never signals. The signals are conveyed to the area of taste perception in brain and then taste recognition process is completed. In this paper, the progress of the composition of taste receptors, taste receptor mediated signaling pathways and gustatory information as well as the nerve conduction are briefly reviewed.
