Comparison of Volatile Components in Ginkgo Fruits Stored in Different Conditions by Electronic Nose

Abstract

Abstract: In order to analyze the properties of volatile components in ginkgo fruits stored in different conditions, an electronic nose FOX4000 was used to detect the volatile odors of ginkgo fruits treated with different preservatives and packaged with different materials after 140 days of storage at 4 ℃. The results indicated that the cumulative contribution rates of the fist and second principal components and discrimination index for ginkgo fruits with different material packaging treatments were 99.44% and 94, respectively, while those for ginkgo fruits with different preservative treatments were 99.48% and 86, respectively. Electronic nose allowed sensitive distinguishing among the significantly different volatile odors of ginkgo fruits due to the different preservation and packaging treatments.

Key words: ginkgo seeds, preservative, packaging material, electronic nose, principle component analysis (PCA)
