Application of Electronic Nose Equipment on Identification of Natural Apple Essence

Abstract

Abstract: In this paper,the natural apple essence samples known only for the production date were identified by using electronic nose. Then, the acquired data were analyzed by principal component analysis(PCA) and discriminant factor analysis(DFA). The results indicated: the product quality is closely related to its production date. The samples of Mouping Corporation were divided into two groups with Oct 31, 2004, and Baishui Corporation samples of the year 2005 can be obviously differentiated from samples of the year 2004.

Key words: electronic nose, natural apple essence, PCA, DFA
