We have developed an electronic sensor (“sniffer”) that measures fruit ripeness rapidly and nondestructively by measuring the aromatic volatiles that are naturally emitted by ripening fruit. In this study, we evaluated the potential of using the fruit ripeness sniffer in the quality sorting of blueberries. Blueberries were first visually classified into four distinct ripeness classes: unripe; half-ripe; ripe; and over-ripe and quantitatively measured for color, firmness, TSS, and sugar acid ratio. Ripeness classification accuracy with the sniffer matched or exceeded that of all other ripeness indices. The sniffer differentiated unripe, ripe and over-ripe berries within one second, but could not distinguish between the unripe and half-ripe class. Detection of l-2 damaged or 1-2 soft fruit spiked within a large container of 24-37 high quality ripe fruit was also achieved, but required a response time of 10 seconds. Electronic sensing of aromatic volatiles may be a useful new technique in the grading and sorting of blueberries.

the ripeness index was ≈4.2 and 2.2 in 2007 and 2008, respectively ( Uceda and Frias, 1975 ). Environmental conditions are summarized in Table 1 . Temperatures during the trial were cooler in 2007 than in 2008, but similar environmental conditions

Fruit splitting and cracking occurs in rabbiteye and southern highbush blueberries if they receive preharvest rainfall when fully ripe or approaching full ripeness. The splitting can be particularly severe if the rain follows a long period of dry
