The aim of this study was to determine the optimum harvest time of ‘Jinhong’ plums. In 2013, differences in fruit quality and volatile components of ‘Jinhong’ plum at different harvest dates were studied in a field experiment in a plum orchard at Shandong Institute of Pomology. The results showed that fruit weight and soluble sugars, vitamin C, tannin, anthocyanin, and calcium content of the fruit increased with delay in harvest time. The soluble solids and total acid and total flavonoids content first increased and then decreased with delay in harvest time, and the firmness decreased with delay in harvest time. Plums could release unique volatile compounds at different harvest dates, but the rates of volatile compound synthesis decreased as the delay in harvest time increased; an electronic nose was sensitive to changes in volatile compounds in plums harvested at different times. The optimal harvest time of ‘Jinhong’ plums in central Shandong was 20-25 July.
