Experiment on Different Storage Temperature Impact on Litchi's Quality Change

Experiments were conducted to investigate the close to freezing point (CFP) storage effect of litchis. The litchis are stored under two different kinds of storage conditions with different temperature. One part of the litchis is stored under CFP condition of which the temperature is -1.2 °C and the humidity is 87%, and the other part is stored under ordinary cold condition of which the temperature is 3 °C and the humidity is 87%. The quality of the litchis is detected periodically. The research results show that, after 35 days of CFP storage, litchi's amino acids content, has significantly increase, meanwhile VC, reducing sugar, acidity, water content and soluble solids content of litchi decreased much less than ordinary storage's. Therefore, the storage effect of litchi in CFP storage is more superior to that of ordinary cold storage.
