Effect of high-carbon dioxide and low-oxygen controlled atmospheres on postharvest decays of apples.

Type of article: Article

Summary

Controlled atmosphere storage with CO2 concentration higher than 2.8% reduced the development of lesions caused by Botrytis cinerea, Penicillium expansum and Pezicula malicorticis on McIntosh, Delicious and Golden Delicious apples stored for 61 days at 0 deg C. Low-oxygen atmospheres were less effective for decay control. Older apples stored in air for 8 months at 0 deg C prior to the CO2 treatment had a higher incidence of brown skin discoloration (scald) when exposed to CO2 concentration higher than 8% than younger fruit stored in air at 0 deg C for 7 weeks before receiving controlled atmosphere treatments. Apple firmness, soluble solids, and titratable acidity were not adversely affected by the high-CO2 or low-O2 treatments.
