Gray Mold Rot

Hedelfingen sweet cherries (Prunus avium L.) were inoculated with spores of Botrytis cinerea and then fumigated with 30 mg L−1.of thymol, acetic acid, or ethanol for 25 min before sealing in modified atmosphere packages and placing into cold storage. After 10 wk of storage, thymol or acetic acid reduced gray mold rot of B. cinerea inoculated cherries from 36 to 0.5% or 6%, respectively. Ethanol was not effective in controlling gray mold rot. Sweet cherries inoculated with B. cinerea and fumigated with thymol had lower total soluble solids, higher titratable acidity and higher stem browning than other treated or non-treated cherries. Key words: Cherry, fumigation, modified atmosphere packaging, storage, Botrytis cinerea

Modified Atmosphere Packaging (MAP) in combination with temperature control were investigated for qualify enhancement of sweet cherries (Prunus avium L.). `Bing', `Lambert' and `Rainier' cherries (1 kg/pkg/rep) were wrapped in 1 of 3 different MAP films (5,303; 8,900 and 11,286 cc/sq M/24 hrs of O2 and stored at 0 or 4 C for 3 weeks. Post-storage evaluations included both fruit and stem color, fruit firmness, weight loss, soluble solids, titratable acidity, bruising and pitting valuations, respiration rates and visual assessment. MAP films helped maintain fruit and stem color, and fruit firmness, Whereas weight loss and bruising were reduced. Visual assessment was best with fruit in MAP film packages, There was little change in soluble solids and titratable acidity among fruit in the different MAP films. Control (unwrapped) fruit had considerably higher soluble solids and titratable acidity than wrapped fruit. This difference in soluble solids and titratable acidity between control and MAP fruit was associated with a considerable weight loss in the control fruit. Respiration rates of the fruit varied among the different MAP films and was cuitivar dependent. Fruit stored at 0 C had better quality after 3 weeks of storage than fruit stored at 4 C.

The effect of CO2 concentrations on the preservation of sweet cherries in modified atmosphere packaging was greatly different. In the present paper, an accurate gas-regulating storage device was used to set the concentrations of CO2 at 0%, 5%, 10%, 15%, 20% and 25%, respectively (O2 was set at 5% and the remaining parts were filled with N2) to store sweet cherries. Then the quality change of sweet cherries was determined aproximately from –1 to +1 °C and from 80 to 85% relative humidity. The results showed that all six air treatments had a certain inhibitory effect on deterioration of sweet cherries. In particular, the 10% CO2 group could reduce rotting rate, maintain firmness, delay the change of soluble solids and vitamin C, reduce the activity of polyphenol oxidase and peroxidase. This group always had good firmness, nutrition and taste after 120 days of storage. So the 10% CO2 concentration provides suitable gas storage conditions of sweet cherries in modified atmosphere packaging.<br /><br />

Noni fruit (Morinda citrifolia L.) is a herbal remedy known for its therapeutic and nutritional value. However, it is perishable and subject to rapid postharvest deterioration that shortens its shelf life during storage. Therefore, this study investigated whether hot water dipping (HWD; 60°C, 1 min) and Modified Atmosphere Packaging (MAP; carbon dioxide and nitrogen) could prolong noni's shelf life. The noni physicochemical properties such as colour, firmness, weight loss, total soluble solids, titratable acidity and scopoletin content were monitored during six days of storage at room temperature. During storage, the noni skin colour changed from greenish-yellow to translucent yellow, but HWD storage was stopped on day 2 due to black spots' formation. The reduction of weight loss was significantly lowest in both MAP treatments (1.39–1.74%). Among these, N2-based had a significantly higher scopoletin content (27.12 mg/g) and firmness (0.8 N) compared to CO2-based, suggesting that it was the most effective postharvest treatment to efficiently prolong the shelf life and retained the quality and stability of noni during storage.

Testing Performance

The performance of three relatively new nondestructive cherry firmness devices and a penetrometer were evaluated and compared with the firmness testing performance of an Instron Universal Testing Machine. The inherent variability of the nondestructive devices was estimated by repeated measurement of a uniform, symmetrical, and resilient rubber ball. Analysis of residuals from correlations between each device and the Instron from firmness testing on common samples of sweet cherries (Prunus avium L.) confirmed the relative variability of the nondestructive devices, and estimated measurement reliability of the penetrometer. Subjective firmness sensing by compression of cherries between the fingers of human evaluators proved to be less reliable than the devices tested. Sweet cherry firmness correlated reasonably well with skin color, with the strength of the correlations from each device agreeing with device ranking in terms of firmness measurement reliability. Firmness correlated poorly with soluble solids, titratable acidity, and specific gravity; soluble solids correlated well with specific gravity; and skin color correlated reasonably well with both soluble solids and specific gravity. Fruit surface pit volume, induced by a specific impact force from a ball bearing, correlated relatively well with fruit firmness measured by the penetrometer, but poorly or inconsistently with measurements from the remaining firmness devices.

The influence of modified atmosphere packaging (MAP) on quality attributes and shelf life performance of ‘Friar’ plums (Prunus salicina) was studied. Plums were stored at 0 °C and 85% relative humidity for a 60-day period in five different box liners (LifeSpan L316, FF-602, FF-504, 2.0% vented area perforated, and Hefty liner) and untreated (control). Flesh firmness, soluble solids concentration, titratable acidity, and pH were unaffected by the box liners. Fruit skin color changes were repressed on plums packed in box liners that modified gas levels and weight loss was reduced by the use of any of the box liners. Plums packed without box liners (bulk-packed) had ≈6% weight loss. High carbon dioxide (CO2) and low oxygen (O2) levels were measured in boxes with MAP box liners (LifeSpan L316, FF-602, and FF-504). Percentage of healthy fruit was unaffected by any of the treatments during the ripening period (shelf life) after 45 days of cold storage. However, after 60 days of cold storage, fruit from the MAP box liners with higher CO2 and lower O2 levels had a higher incidence of chilling injury (CI) symptoms, evident as flesh translucency, gel breakdown, and “off flavor” than fruit from the other treatments. Overall, results indicate that the use of MAP box liners is recommended to improve market life of ‘Friar’ plums up to 45 days cold storage. However, the use of box liners without gas control capability may lead to CI symptoms in fruit cold-stored for longer periods.

`Hedelfingen' and `Lapins' sweet cherries (Prunus avium) were stored in air or in two types of modified atmosphere (MA) bags (LifeSpan 204 and 208) at 3 °C (37.4 °F) and 90% relative humidity for 4 weeks. Various analytical and quality measurements were conducted weekly on `Hedelfingen' cherries, whereas on `Lapins' these were done initially and at the end of 4 weeks. For `Hedelfingen' cherries, there were differences in carbon dioxide (CO2) and oxygen (O2) composition within the MA bags, depending on the bag used. This resulted in slightly better cherry quality for the bag with lower O2 permeability (L204), which equilibrated at 4% to 5% O2 and 7% to 8% CO2. For `Lapins', the two MA bags showed concentrations of 9% to 10% O2 and 8% to 9% CO2 and similar final fruit quality. There was a significant weight loss for the control treatments over time (6% to 13%), whereas the MA treatments showed minimal losses. A higher incidence of cracking and decay was observed in MA treatments of `Hedelfingen' but not in `Lapins'. Control cherries had significant shriveling and browning of stems; MA-stored cherries had green and healthy stems after 4 weeks. No significant differences were observed in pH, acidity, soluble solids, firmness, and hue angle among the storage treatments. MA packaged cherries seemed to maintain better color than control cherries over time. Similarly, MA cherries had better appearance and eating quality after 4 weeks when compared to control cherries.

Aims: The objectives of the present study were to evaluate effects of aqueous 1-methylcyclopropene (1-MCP) on quality of cucumber fruit, and to compare with/to gaseous 1-MCP and modified atmosphere packaging (MAP) applications. Study Design: A randomized complete block design (RCBD) was set up for the experiment. Place and Duration of Study: Department of Horticulture, Bingol University, Turkey; between September - December 2017.  Methodology: Cucumber fruits (ErdemliF1) were either treated with aqueous or gaseous 1-MCP (1 ppm), or left untreated for MAP storage or controls. The fruits were afterwards put into PET clamshell containers except for MAP application and stored 23 ± 1°C for 10 days for simulating retail shelf-life conditions. Samples of cucumbers were then tested periodically to record changes in quality as determined by weight loss, firmness, color, gas composition (O2, CO2 and N2), total soluble solids, pH, titratable acidity, chlorophyll content, and decay during the storage time. Results: Neither aqueous nor gaseous 1-MCP application had a significant effect on weight or firmness loss. According to peel color values recording during the storage period, there were no significant differences among the treatments. Total soluble solids, pH or titratable acidity did not show a significant change or variation among treatments during the storage. Fruits stored in modified atmosphere packages showed higher chlorophyll a amount than fruit treated with 1-MCP.   Conclusion: The study revealed that neither aqueous 1-MCP application nor gaseous 1-MCP application is effective for retaining quality loses and consequently for extending shelf life of the cucumbers kept at 23°C.

Spondias mombim L. fruit, commonly known in the Brazilian Northeast as “caj,” has increased its acceptance locally and abroad in recent years due to its exotic and delicious pulp. Spondias mombim fruit can be eaten raw or as juice, jellies, and sweet. Trade in S. mombim, however, has been limited by the highly perishable nature of the fruit. Comprehensive studies on proper postharvest technologies for its storage and enhanced shelflife are required to improve its commercial performance. The determination of proper storage temperature allows reducing the rate of metabolism without causing chilling injury. In addition, modified atmosphere packaging, by using low-density polyethylene (LDPE), may delay fruit ripening. Combination of proper temperature and film O2 and CO2 permeabilities, therefore, may enhance the postharvest shelflife of S. mombim fruits. Ripened fruits were stored with and without film, at temperatures varying from 16 °C to 5 °C, at 0.5 °C steps, in order to set proper storage temperature and shelflife. Changes in fruit weight loss, firmness, soluble solids, pH, titratable acidity, sugars, CO2 production, ascorbic acid, and carotenoids contents were measured during storage. Storage of S. mombim, wrapped with LDPE, at 8 °C allowed quality maintenance and increased the fruit postharvest shelflife by 12 days, without causing chilling injury.

Postharvest Treatments

In this article, effect of modified atmosphere packaging (MAP) and different postharvest treatments on quality of litchi (Litchi chinensis Sonn.) fruit was investigated. Quality indexes of litchi during cold storage at 4 ± 1 oC were measured in terms of decay, total soluble solids, titratable acidity, color, anthocyanin content and incidence of microbiological infection. These indexes were determined at harvest and 7, 14, 21, 28 and 35 days after storage. The results suggested that after 35 days of storage, the pericarp browning and fruit quality deterioration can be improved compared to the control by dipping fruit is hot water at 47 oC in 7 min., followed by oxalic acid solution (pH = 3 in 6 min.) and finally packed in MAP bag (LDPE, thickness of 30 µm incorporated 3-5 % silica additive) and stored at 4 ± 10C and relative humidity of 90 %.
