Honey from different nectar sources was analyzed by electronic nose (e-nose), including litchi honey, rape honey, acacia honey, linden honey and vitex honey. Orthogonal experiments were done to optimize the measuring factors including weight of samples, head-space temperature, and incubation time so that a better performance can be obtained. Besides, combined with soft independent modelling of class analogy (SIMCA), genetic algorithm (GA) was applied in the selection of sensors to improve the quality of classifier and the accuracy of pattern recognition. The result indicated that the e-nose acquired a better performance of repeatability and discrimination at 60 C, with incubation time of 120 s and quantity of 6 g. With No. 2, 10, 14, 15, and 16 sensors selected, e-nose had better ability to classify different kinds of honey. The accuracy of SIMCA is 80% after the optimization.
