Abstract: In this work, a gas chamber which is of a bionic functionality was designed based on the special structure and the olfactory principle of an adult nasal. The smell sensor is appropriately selected based on the smell of pork and sensor experiments. The support vector machine (SVM) serves as the method for pattern recognition. It has been demonstrated that the accuracy of the system for pork freshness detection is up to 96.45% by means of physico-chemical examination. The experimental results indicate the feasibility of using bionic electronic nose system for pork freshness detection.

Key words: bionic engineering, pork, freshness, bionic electronic nose, support vector machine
