Abstract:

The aroma composition in jucy peaches was detected by an electronic nose during diferent storage time.The aroma composition emanating from the Jucy peaches was sampled by PEN3 systems,and the response values of PEN3 was obtained,The data was analyzed using principal component analysis (PCA) and linear diserimination analysis (LDA),respectively.The results showed that electronic nose was able to better classify the jucy peaches by LDA method,and a clear distinction was available among jucy peaches on 0day,day1～day3 and day4～day6.Moreover,The changes of aroma composition reflected the regularity of physiological and quality change in jucy peaches during the storage time.The sensor 6,sensor8 and sensor5 played important roles in the quality detection of Jucy peaches by using loadings analysis.
