Zusammenfassung:	The invention provides a post-harvest treatment method for improving the whole fruit flavor quality of fresh tomatoes, which comprises the following steps: storing picked fresh tomatoes at 10-20 DEG C for 30-50 hours; the stored tomato fruits are taken out and placed in a bath type ultrasonic processor for ultrasonic treatment; the frequency of the ultrasonic treatment is 60-80 KHz, the sound density is 15-40 W/L, the time is 1-3 min, and the temperature is 10-20 DEG C; and after the ultrasonic treatment is finished, taking out the tomato fruits, wiping the tomato fruits, and storing the tomato fruits at 4-10 DEG C for 24-168 hours. According to the method disclosed by the invention, short-time ultrasonic treatment and low-temperature storage are carried out on the picked tomatoes during the storage period, so that the content of characteristic volatile flavor substances in the tomato fruits can be effectively increased; and the content of p-phenylethanol, n-hexanal, trans-2-hexenal, trans-2-heptenal, phenyla
