Q. What do you mean by sensory perception?
The appearance of a food can be evaluated in terms of colour, surface characteristics such as smoothness of a surface, dry surface, glossy surface or the exterior appearance such as lump formation, thickness or thinness, layering etc.
Taste
Individuals respond to a product on the basis of their sensory perception and judge the product quality differently. The auditory sense is the least used in appreciation of food quality, however, the senses for taste stimulation has a strong influence on the acceptability of food quality.
Taste is sensed by taste buds, which you may already know by now, are located in the papillae on the tongue. Taste buds are located in the epithelium and on the parts of the tongue where the food contacts the most during chewing and swallowing. Taste sensations which the taste buds register are sweet, salt, sour and bitter.
