摘要: Abstract Gas transfer properties of wheat gluten (WG) coated paper and their ability to fulfil the requirements in eMAP fresh parsley were studied. Permeation gases through WG-paper was demonstrated be RH-dependent closely related structural modification WG layer. Formation micro-cracks evidenced dry conditions; but when increasing RH, plasticisation occurs within protein layer micro-fractures reduced until disappearance. This reversible phenomenon allowed WG-layer recover its integrity at RH higher than 70%, character expressed such conditions. When used 20 °C 80% as part packaging parsley, modified atmosphere created a steady state 11 kPa O 2 4.5 kPa CO reached after 45 h. In conditions, overall quality leaves remained acceptable during 8 days, with only 28% loss chlorophyll.
