Modified atmosphere packaging affects the incidence of cold storage disorders and keeps 'flat' peach quality.

Firm-breaker and firm-mature flat peaches (Prunus persica cv. Paraguayo), harvested from a commercial orchard in Spain, were stored in air for 10 days at 20 deg C, or precooled and sealed in 1 of 2 unperforated films or 1 macroperforated polypropylene film for 14 or 21 days at 2 deg C. The atmosphere inside the macroperforated film bags remained close to the composition of air during storage. In unperforated bags, steady state atmospheres were reached within 6 and 9 days: firm-breaker fruits (12% CO2 and 4% O2 in standard type polypropylene, 23% CO2 and 2% O2 in oriented-type polypropylene); firm-mature fruits (22% CO2 and 3% O2 in standard polypropylene, and 21% CO2 and 2% O2 in oriented polypropylene). After 14 days storage plus a 3-day shelf-life test, woolliness and slight internal browning developed in fruits stored in macroperforated polypropylene. Ethanol and acetaldehyde accumulated to higher levels in oriented polypropylene bags for both firm-breaker and firm-mature fruits. Modified atm

ospheres in both unperforated bags were associated with lower weight loss, less senescence and chilling injury, absence of decay, and delayed ripening after a shelf-life period.
