EFFECT OF MODIFIED ATMOSPHERE PACKAGING (MAP) WITH INCREASED LEVELS OF O₂ ON POSTHARVEST QUALITY OF IRANIAN ‘SHAHROODI’ TABLE GRAPE

Table grape as a non-climacteric fruit with low physiological activity is sensitive to water loss and fungal infection mainly caused by Botrytis cinerea during postharvest handling, storage and marketing.
In the present study a factorial experiment was conducted in a randomized design with three replications using two gas combinations, 10% CO₂+15% O₂ and 10% CO₂+60% O₂, to evaluate the efficacy of modified atmosphere packaging to control decay and keeping postharvest quality in Iranian table grapes compared to controls.
Fruits were stored at 1°C and 80-90% RH for 60 days.
Samplings were carried out every 15 days and measurements were made following the placing of fruit for 1 day at room temperature.
Our results showed that decay incidence for control bunches and those kept in MAP of 10% CO₂+15% O₂ began at day 30. We observed that increasing O2 level from 15 to 60% could delay decay incidence until day 60. In addition both fruit browning and pedicle desiccation decreased for the latter treatment.
