- We used silicon gum film as window on MAP for storing green asparagus for 30days.
- Silicon gum film was high permeability for gases and kept optimal atmosphere.
- Green asparagus stored in MAP without silicon gum film windows had poor quality.
- To decrease the ethylene concentration in atmosphere was effect for green asparagus.
- Initial atmosphere also had some effects on the quality of stored green asparagus.
Packages of green asparagus (Asparagus officinalis L.) spears with or without silicon gum film windows were flushed in two different modified systems (50 mL Lâ1 O2 with 100 mL Lâ1 CO2 and 100 mL Lâ1 O2 with 100 mL Lâ1 CO2, with N2 as a balance gas) and stored at 2 ± 1 °C for 30 days. The changes in gas headspace, sensory, respiration rate, ascorbic acid content, soluble solid content and chlorophyll content were investigated. The results showed that green asparagus spears stored in MAP with silicon gum film windows, the gas exchange between packages and surrounding atmosphere through the silicon gum film windows induced an in-package optimum atmosphere for green asparagus spears stored at O2 above 21 mL Lâ1, CO2 below 157 mL Lâ1 and ethylene below 15.84 μL Lâ1. These packages prevented anaerobic respiration to get good odour score, and were able to keep a relatively low respiration rate and reduce loss of ascorbic acid. A low concentration of ethylene atmosphere was effective for inhibiting chlorophyll degradation, which resulted in a high appearance score. The initial atmosphere in packs also affect the quality attributes, where 50 mL Lâ1 O2 and 100 mL Lâ1 CO2 initial atmosphere was preferred.
