Alternatives to sulfur dioxide to maintain quality of table grapes, including various combinations of rachis removal, chlorinated wash, hot water treatment, and modified atmosphere packaging, were explored in this study. Grapes were prepared by cutting off the rachis 1 to 2 mm from the fruit or by keeping the clusters intact. After initial preparation, short-stem and cluster grapes were subjected to chlorinated wash and/or hot water (45 °C, 8 min) treatment and packaged in plastic trays sealed with a gas-permeable film. The treated grapes as well as the commercially packed grapes (COM) in their original packages were stored at 5 °C for up to 4 weeks. Hot water treatment resulted in significantly (P < 0.05) higher oxygen retention and lower carbon dioxide accumulation in package headspaces, maintained a firmer texture, higher overall visual quality, lower decay rate, and lower microbial populations than other treatments or COM during the entire storage period. Grapes that were cut from the rachis and treated with hot water and chlorine maintained the highest quality for 4 weeks with the least decay among all treatments. A chlorine prewash treatment significantly (P < 0.05) reduced microbial populations on cluster grapes and maintained better overall quality. Conventional COM grapes developed dark decay and lost turgidity and were of unacceptable quality at 28 days of storage.

Pomegranate Fruit

“Wonderful” pomegranates can be stored under modified atmosphere (MA) conditions for up to 3–4 months after harvest. Until recently, the harvested fruit first needed to be transferred to the packing house and packed in MA bags in cartons or plastic boxes before cooling to the desired temperature and subsequent cold storage. During the last few years, together with StePac Ltd, we have developed a new methodology in which “Wonderful” pomegranate fruit are directly harvested into large 80 kg or even 320 kg bulk Xtend® MA bags in harvest bins, and then immediately transferred from the field to commercial cold storage rooms without the necessity of repacking the fruit at the packing house. In this study, we evaluated the postharvest storage performance and fruit quality of “Wonderful” pomegranates stored in bulk 80 kg Xtend® MA bags in harvest bins for various periods of 4, 8, 12, and 16 weeks at 7 °C followed by 1 week in shelf life conditions at 20 °C. The results show that “Wonderful” pomegranates can be maintained in bulk Xtend® MA bags in harvest bins at excellent quality with minimal losses for at least 12 weeks after harvest. Overall, this new suggested procedure allows direct transfer of large volumes of fruit from the field to cold storage rooms without intermediate transferring to the packing house, thus saving precious time and extra packaging and labor costs, and ensuring better maintenance of the cold storage chain.

A field trial was established in the Mildura district, to compare the effects of trellis type (single T, double T, Y and sloping T) on the yield and fruit quality of 5 table grape varieties (Cardinal, Waltham Cross, Italia, Ruby Seedless and Emperor). Over a 3-year period (1978-80), berry yield proved insensitive to trellis type for most varieties and also as the mean of all varieties in 2 years out of 3; however, the 3 larger trellises led to significantly (P<0.05) increased berry Brix levels, improved red colour levels on Cardinal, Ruby Seedless and Emperor grapes, and higher mean berry weights for Cardinal, Waltham Cross and Italia varieties, compared with grapes grown on the single T trellis. Since differences in Brix, red colour levels and berry size were, generally, not significantly different between the 3 large trellises tested, and the sloping T trellis is simpler and easier to erect, it is concluded that the sloping T trellis is a suitable, cost-effective trellis to use for the production of table grapes in the Murray Valley.

Modified atmosphere packaging (MAP) technology is gaining popularity worldwide for its potential of extending shelf life of fresh produce with better fruit quality. Effect of MAP (using Xtend® bags), was investigated on postharvest storage life and quality of mango cvs Sindhri and Sufaid Chaunsa stored at 11°C with 80-85% RH for 4 and 5 weeks respectively, in comparison with un-bagged (control) fruit. Uniform physiological mature fruit of Sindhri and Sufaid Chaunsa were harvested from a commercial mango orchard along with 4-5 cm long pedicel and were de-sapped in 0.5% lime solution (to avoid sap burn injury). Later on fruit were given cold water fungicidal dip (Sportak @ 0.5ml/L, Active Ingredient: Prochloraz) followed by hot water treatment (52°C; 5 min). After shade drying and pre-cooling (11°C; 10-12 hours), fruit were packed according to the treatment combination and stored at 11°C. Fruit of both varieties were removed after 2, 3 and 4 weeks of storage followed by ripening at 24±2°C with an additional removal after 5 weeks for Sufaid Chaunsa only. Fruit quality was evaluated for various bio-chemical, organoleptic and physical parameters at two stages of ripening (at removal day and at final ripening day). Fruit of both varieties stored in MAP exhibited better firmness and retained green colour as compared to un-bagged fruit. Quality of fruit subjected to postharvest fungicidal application and hot water treatments and stored under MAP at 11°C showed better peel colour development and less disease development. Moreover, storage durations and post storage ripening stages significantly affected fruit peel colour, textural softness and disease development. Further, cv. Sindhri showed better storage potential with lower disease incidence as compared to cv. Sufaid Chaunsa which warrants further studies on disease control aspects.

The effects of combinations of modified atmosphere packaging (MAP) with potassium permanganate (KMnO4) based ethylene scrubbers on the storage life and fruit quality of nectarine (Prunus persica cv. Bayramiç Beyazı) were investigated. Three different types of ethylene sachets (contained 3, 7 and 10 g KMnO4) were used and placed beside fruits in polypropylene baskets then lined with MAP. Fruits were stored at 0-1°C and 90% relative humidity throughout 40 day. During the cooling storage period, O2 and CO2 percentage in MAP, fruit firmness, total soluble solids, titratable acidity, ascorbic acid, total flavonoid content, total phenolic content, total antioxidant content and chilling injury (CI) were determined at 10 day interval. KMnO4 treated fruits had shown delayed ripening, reduced respiration and retained of higher firmness. As the dose of KMnO4 treatment increased, it was determined more positive effect on fruit quality. 10 g KMnO4 treatment was most effective in the retention of higher biochemical compounds and inhibition of CI symptoms. The results indicate that KMnO4 treatment, as well as MAP application, should be highly recommended for retaining the fruit quality of cold-stored ‘Bayramiç Beyazı’ nectarines and fruits treated with 10 g doses of KMnO4 could be stored for 40 days with good quality.
