Abstract EN
The effect of thermal treatments on the quality and aroma of watermelon juice was evaluated.
Watermelon juice was pasteurized via ultrahigh temperature (UHT, pasteurized at 135°C for 2 s), low temperature long time (LTLT, pasteurized at 60°C for 30 min), and high temperature short time (HTST, pasteurized at 100°C for 5 min), respectively.
UHT and LTLT reduced the total flora count and maintained the color of the pasteurized juice, while the HTST led to a significant color difference.
A total of 27, 21, 22, and 21 volatiles were identified in the unpasteurized juice, UHT, LTLT, and HTST, respectively.
The typical watermelon aroma, including (3Z)-3-nonen-1-ol, (E)-2-nonen-1-ol, 1-nonanal, (2E)-2-nonenal, and (E,Z)-2,6-nonadienal, was abundant in the LTLT.
Consequently, the aroma of the LTLT was similar to that of unpasteurized juice.
Moreover, the shelf life of the LTLT reached 101 and 14 days at 4 and 25°C, respectively.
Hence, the LTLT was the best way to maintain the quality and aroma of watermelon juice.
