Sensory testing places worth on a product and helps to determine its acceptability in the marketplace. There are many kinds of tests that are given to evaluate sensory perceptions of a product. Difference testing is one of the tests that are used in sensory evaluation. There are many varieties of Difference Tests. Triangle or Duo-trio Tests can measure the overall difference between two products.
People go through a particular process during a sensory experience.
First there needs to be some type of stimulus which creates some kind of sensory sensation. After a sensation has occurred, the nerves in that area of the body send signals to the brain creating a perception of the experience. Another response would have been that they perceived the cheese to be hot, but not hot enough to spit it out, and they respond by chewing and swallowing the bite of pizza. Since the main focus of food preparation is for consumption purposes, it must create an acceptable sensory experience. As new food products are created and put on the market, it is important to know what the consumers desires.
