Abstract
The effects of retail-size modified atmosphere packaging bags on postharvest quality and physiology of 0900 Ziraat sweet cherries (Prunus avium L.) were investigated.
Fruit were harvested at an ideal harvest maturity (18.8% SSC, hue° 63.06) in Ulukisla.
Within a few hours after harvest, the cherries were immediately transported to Narpak Packinghouse in Mersin.
Upon arrival, they were hydrocooled to a 2°C pit temperature, then dumped onto a GP Grader packing line to be sorted and sized.
Cherries were packed in Xtend CH-49 modified atmosphere packaging bags.
In the experiments, three retail-size MAP bags were used (500 g, 700 g and 1000 g). MAP bags were compared to polyethylene bags of the same sizes.
All cherries were stored at 0°C for 7, 10, 14 and 21 days to simulate market conditions.
After these storage periods at 0°C, half of the cherries were analyzed immediately and the other half was transferred to 20°C (shelf-life) for 3 d.
Cherries were analyzed for fruit elasticity (shore), SSC (%), titratable acidity, color (hue angle), respiration, weight loss (%), stem chlorophyll content and waste (%). Cherries from all three types of retail-size MAP bags benefited from modified atmospheres, especially in terms of firmness, color and taste.
MAP drastically increased fruit shelf-life and appearance compared to the control. 0900 Ziraat cherries can be packed in retail-type Xtend MAP bags, stored up to 21 days and still maintain their quality, even after additional 3 d shelf-life at 20°C.
