Sensory Intelligence Analysis System (Electronic Nose / Electronic Tongue)
Sensory Intelligence Analysis System (Electronic Nose / Electronic Tongue) With the development of food sensory theory and the application of modern multidisciplinary methods, food sensory science has gradually formed a complete set of scientific systems and become the most distinctive discipline in modern food science. , With its theoretical, practical and technical characteristics, it has become an important part of the development of modern food science and technology and food industry.
Using instruments to replace people and using sensory evaluations of human senses (ears, eyes, nose, tongue, and brain) with smart senses has always been a human dream and a goal to fight for.
The sensor technology that simulates human sensory organs is a new technology developed in the 1980s. For example, an electronic nose that simulates a person's sense of smell, an electronic tongue that simulates a person's taste, and the like.
Electronic nose is different from chemical analysis instruments such as chromatographs. What it gets is not the qualitative or quantitative result of the odor component of the measured substance, but the overall information of the volatile component in the substance, that is, the “fingerprint data” of the odor. It shows the odor characteristics of the substance, thus achieving the objective detection of the odor of the substance. , identification and analysis. For example, for the detection of dairy products, the classification of vegetable oils, etc.
Although electronic tongue technology has shown better application prospects in food and medicine, it still needs further maturation and improvement. Electronic tongue is an instrument developed to imitate the taste system of mammals, especially humans. It mainly consists of three parts: taste sensor array, signal collector and pattern recognition system. The sensory sensor array corresponds to the tongue of a mammal. There are several electrodes that have different taste sensitivity. The signal collector is like a neurosensory system. It collects the excited electrical signals and transmits them to the computer. Pattern recognition technology is equivalent to the brain, the data processing and pattern recognition of the signals transmitted to the computer, and finally get the taste characteristics of the material.
