Evaluation of active and passive systems of modified atmosphere for preservation of minimally processed collard green (Brassica Oleraceae, var. Acephala)
Different systems of atmosphere modification were evaluated for preservation of minimally processed collard green. Vitamin C content of the produce and O 2 and CO 2 concentration in the package were determined during storage in low density polyethylene (LDPE) film of 30 or 60 mm with active or passi...

| Sumario: | Different systems of atmosphere modification were evaluated for preservation of minimally processed collard green. Vitamin C content of the produce and O 2 and CO 2 concentration in the package were determined during storage in low density polyethylene (LDPE) film of 30 or 60 mm with active or passive atmosphere modification or in 30 or 60 mm films, with or without perforations and with actively modified atmosphere. None of the systems provided adequate atmosphere modification due to low gas permeability of the films. The resulting anaerobic atmosphere inside the packages led to physiological disturbances and rapid loss of vitamin C content. Although perforations prevented anaerobiosis, the gas concentrations in the package remained unsatisfactory. |
