Abstract

The work aims to obtain the most suitable packaging solution for juicy peach through researching the effect of different film packaging on the quality of juicy peach at 0 ℃. Juicy peaches were packaged with 0.035 mm anti-fogging CPP film (CPP), 0.025 mm polyvinyl chloride film (PVC), 0.03 mm micro porous film (MF) and 0.03 mm polyethylene film (PE) respectively, and stored at 0 ℃ for 48 days. After 48 days stored at 0 ℃, the quality of juicy peaches with CPP film package was the best. The sensory evaluation was 6.83; weight loss, firmness and relative electric conductivity were 2.16%, 56.33 N and 38.11% respectively; soluble solid, titratable acid and soluble sugar content were 10.2%, 0.16% and 6.05% respectively; and 8.11 mg vitamin C is contained in 100 g juicy peach. In conclusion, film packaging can effectively restrain the increase of weight loss ratio and relative electric conductivity, and delay the decrease of soluble solid, titratable acid, vitamin C and soluble sugar content and keep high sensory evaluation of juicy peaches during cold storage. CPP film is the best to keep the quality of juicy peaches.
