Modified Atmosphere Packaging Extends Freshness of Grapes 'Campbell Early' and 'Kyoho'

摘要

To investigate the effects of modified atmosphere packaging (MAP) on freshness of 'Kyoho' and 'Campbell Early' grapes, changes of fruit physiological attributes and respiration and berry abscission in the abscission zone were examined during 60 days of cold storage at 0 deg C with 90% relative humidity. Grapes packaged with 0.03 mm polyethylene film maintained berry firmness, soluble solid content, titratable acidity, and peel L value compared with control treatment. MAP with 0.03 mm polyethylene film also reduced respiration rate, decay and weight loss. In contrast, antifogging and perforation film (0.20 and 3.14%) accelerated the production of grape respiration, development of decay and berry abscission resulting in loss of marketability after 60days of cold storage.
