Abstract

The work aims to study the relationship between the active fresh-keeping packaging way integrated with double functions and the preservation quality of the wax apple. With active functional films A and E as the raw material for the covering film (the area ratio of film A to film E was 4∶1) and in coordination with a common fruit tray, a double function integrated fresh-keeping package was designed, which was compared with the bare set in the air (O2 with volume fraction of 21% + CO2 with volume fraction of 0.03%). During the 5 days storage, in the environment at the room temperature of (20±2)℃ and relative air humidity of 30%~40%, the designed double function integrated active fresh-keeping package could maintain good sensory evaluation of wax apple, and the sensory evaluation was still over 8 points after five days of storage. The package could greatly delay the decline of the content of TSS and vitamin C of wax apple. After 5 days of storage, the mass fraction of TSS was about 8.2%, and vitamin C content was 5.4 mg/(100 g). Double function integrated active fresh-keeping package can significantly maintain the storage quality of wax apple.
