Abstract:

To meet the needs of fresh-cut rape packaging, this paper adopted the combination of the packaging bags with the modified atmosphere (MA) windows of different permeability and different areas to conduct the tests, and through the analysis of the sensory quality and gas composition in the packaging bags of fresh-cut rape, developed the optimum modified atmosphere packaging (MAP) of fresh-cut rape. The results showed that the suitable MA window for fresh-cut rape was: the transmittance rates of O2 and CO2 were 4×105 and 1.6×106 cm3/(m2·d·atm), respectively; the area of rape needed was 2~6 cm2/kg. Comparing the permeability of modified atmosphere window and film, the permeability amount of O2 and CO2 in packaging bags suitable for fresh-cut rape should be 2.08×103-2.99×103 and 0.96×104-1.32×104cm3/(kg·d·atm) respectively, which could solve the problem of odor and maintain shelf quality for more than 5 days. When the appropriate gas concentration of fresh-cut rape was reached, O2 was 6.50%-9.69% and CO2 was 6.46%-7.10%. The MAP bag can not only improve the storage quality of fresh-cut rape and make fresh-cut rape in the appropriate gas state, but also solve the odor problem caused by anaerobic breathing, and retain the original smell of fresh-cut rape and prolong the shelf life.
