“…The reduction in FWL % with MA treatments is in agreement with results of Pereira et al, (2004) on guava; Rocha et al, (2004) Harb et al, (2006) on cherries; Mortazavi et Al., (2007) on date fruits and Kudachikar et al, (2011) on 'Robusta' banana. The tested MA treatments effect during shelf life period caused significant increases in FWL %.…”

“…Storing fruits of horticultural crops under modified atmosphere decreased fresh weight loss of table grapes (Martines-Romero et al, 2003); guavas (Pereira et al, 2004); apples (Rocha et al, 2004); cherries (Harb et al, 2006); date fruits (Mortazavi et al, 2007) and banana (Kudachikar et al, 2011). While fresh weight loss was higher with MA treatments than control after 2 or 3 days shelf life of guavas (Gad, 2008).…”

Five passive and active modified atmosphere (MA) treatments; i.e., 1-Non MA as control (packing in plastic nits as traditional practice), 2-Passive MA without additions, 3-Passive MA with adding 25g wetted Ca(OH) 2 per sealed package, 4-Active MA 10% O 2 + 3% CO 2 and 5-Active MA 10% O 2 + 6% CO 2 were applied prior to cold storage of Balady lime fruits for periods of 30, 60, 90 or 105 days at 12±1°C and 90-95% relative humidity. Fruits were subjected to active and passive MA in tightly sealed carton boxes. After cold storage, fruits of all treatments were hold for 5 days at 20 °C and 60-70 % relative humidity as shelf period. The target of such research was to clarify effects of modified atmosphere treatments, cold storage periods and their interactions on fruit storability and its quality after cold storage periods and after shelf life during 2010 and 2011 seasons. Fruit samples taken after the tested cold storage and after 5 day's shelf life period exhibited that advancing storage period caused progressive increments in chilling injury index (CII), fruit decay % (FD%), fruit weight loss percentage (FWL %); peel color index (PCI), juice TSS %, Juice % as well as technological index (TI) and TSS / acid ratio. While, juice contents of vitamin C and acidity % as well as pulp firmness after cold storage and after shelf life period were gradually decreased with prolonging the cold storage period. Generally, all tested modified atmosphere treatments reduced chilling injury index, fruit weight loss percentage, fruit firmness, juice %, juice TSS, juice acidity % and TI. Simultaneously, they increased fruit decay%, peel color index as well as TSS/ acid ratio, but, did no significantly affect vitamin C content in fruit juice. Generally, make possible to recommend storage Balady lime fruits (in tight sealed carton boxes at rate of 190± 10 g fruits/ liter) under passive MA with adding 25g wetted Ca (OH) 2 per package treatment for 60 days at 12±1°C and 90-95% relative humidity. This 436 ZAGZOG et al. combination treatment minimized CII and FD % after storage and kept fruits in good quality during the subsequent 5 days shelf period at 20°C and 60-70 % RH.

“…Al-Jasim & Al-Delaimy (1972) reported an increase in pectinesterase activity during the khalal stage of date ripening, which subsequently lead to the breakdown of pectin or softening of fruit. However, dates flushed with 10% or 20% CO 2 in air did not show a significant softening of the fruit compared with other MAP treatments packaged at the same time; this may have been owing to the changed atmospheric conditions slowing enzymatic reactions relating to softening (Kader et al, 1989;Mortazavi et al, 2007). Interestingly, fruit firmness displayed by the MAP dates stored in 10% and 20% CO 2 in air was considerably lower than controlpackaged dates, but unlike control dates, firmness was not caused by dehydration as MAP treatments displayed minimal weight loss over the 27-day storage Figure 1 Effect of different packaging types, (e) control, (D) modified atmosphere packaging (MAP) with air, (m) MAP with 10% CO 2 in air, (X) MAP with 20% CO 2 in air (n) MAP with 30% CO 2 in air (•) MAP with 20% CO 2 in nitrogen on Khalas date firmness (mm) when stored at 0°C for 9, 18 and 27 days.…”

Summary Completely matured tamr stage dates are widely available and consumed throughout the year. However, for some date varieties, the earlier khalal stage crunchy fruit is considered a premium product. This work examines the use of modified atmosphere packaging to extend the shelf life of khalal dates under refrigerated conditions. Modified atmosphere packaging with 10% or 20% CO2 in air was successful in reducing the rate of the ripening processes while control‐packaged dates showed signs of ripening development such as significant weight loss and darkening in date colour (identified visually and as low lactic acid bacteria measurements at 18 and 27 days after packaging), similar to that observed in tamr stage fruit.

“…In this regard, the enzymatic activity of pectin (pectin esterase and polygalacturonate) were the most important factors involved in softening of the fruit firmness. It should be noted that each factor may lead to the maintenance of the fruit firmness so delaying enzymatic activity (Mortazavi, Arzani & Barzegar, 2007).…”

Barhi Dates are an important food and often consumed and sold in the market during the stage Khalal, when the colour is yellow and their taste is sweet with the disappearance of their astringent taste. During the Khalal stage, these dates become physiologically mature with gives the sweet taste. For this reason, they are sold and consumed in a short period of time before these fruits turn into Rutab, a stage at which they lose that distinguishing characteristic. The high moisture, rapid ripening, and delays in transportation or improper storage conditions quickly result in Rutab stage. Thus The Khalal stage lasts for a short time until the fruits get ripe. In the present study, Barhi Khalals were packaged in air (control) and by two types of modified atmosphere packaging: MAP A (5% O2+ 20% CO2 and 75% N2) and MAP B (40% O2+ 20% CO2 and 40% N2). Afterwards, all samples were stored at 5°C for 30 days. On days zero, 10, 20 and 30 of storage, the fruits were evaluated in terms of the changes in the quality indices of weight loss, colour, Total Soluble Solids (TSS), and firmness of the fruits and sensory features. The results showed that the minimum weight loss was 0.45% in modified atmosphere packaging, especially with MAP A and the minimum increase in the TSS was 37.35 Brix° after 30 days of the storage. On the other hand, the results for firmness, colour, and sensory evaluation were better with control packaging.
