Effects of transport fresh-keeping modes on quality of litchi in shelf-life

In order to study the effects of different fresh-keeping transportation modes on the changes of litchi quality during shelf-life，‘Guiwei’ litchi fruit was stored in the display cabinet at low temperature for 30 h after being stored under 3 different storage environments for 10 d，including controlled atmosphere，controlled both temperature and humidity，and controlled temperature，and its qualities were tested every 6 h. The results showed that the marketable fruit rate，L* value and b* value of the litchi fruits under controlled temperature decreased faster than the litchi fruits under another two fresh-keeping modes；there was no significant difference between the litchi fruits under controlled atmosphere and that under controlled both temperature and humidity environment in the shelf-life qualities； no significant effects of different fresh-keeping modes on the litchi fruits’ TSS and TA content was found. The TSS content maintained at 19.5~20°Brix，while TA content maintained at 1.1~1.3 g/100mL.
