Storage Characteristics

In 1987, 1988, and 1989, the behavior of four different table grape varieties including Alden, Concord, Himrod, and Vanessa were studied during storage at 0°C.The first objective of our study was to determine the behavior of table grapes in modified atmosphere packages in terms of general acceptance. After three years of experimenting with these three films we were able to obtain a modified atmosphere of about 3% O2 and 10-15% CO2 at 0°C using a 3 mil thickness LDPE.Our second objective was to use moisture absorbents as a means of reducing the relative humidity inside the void volume of a package by the inclusion of different desiccants in the package to establish a desirable relative humidity.Examining different storage characteristics, our data showed that `Himrod', `Vanessa', and `Concord' grape clusters stored in the presence of KNO3 and KCl had better quality compared to grape clusters stored in the presence of other sorption compounds or controls with no sorbants.

Table grape is a non-climacteric fruit, very sensitive to water loss and gray mold during postharvest handling and storage. The aim of this work was to evaluate the effects of modified atmosphere packaging and chitosan treatment on quality and sensorial parameters of minimally processed cv. ‘Italia’ table grape during cold storage (14 days at 5 °C) and shelf-life (7 and 14 days of cold storage plus 5 days at 20 °C), reproducing a retail sales condition. Our data showed a significant effect of high CO2-modified atmosphere in combination with chitosan and alone on preserving quality, sensorial parameters, and delaying decay of minimally processed table grape. The most effective treatment in terms of preservation of quality, sensory, and nutritional quality was high-CO2 modified atmosphere packaging plus chitosan treatment. The overall results showed that when a proper modified atmosphere packaging is combined with a postharvest chitosan treatment, gray mold growth can effectively be controlled in ready-to-eat cv. ‘Italia’ table grape and that modified atmosphere packaging (MAP) with high levels of CO2 and reduced concentration of O2 in combination with chitosan treatment could prevent the negative effect of high-CO2 in-packages level, like berry browning and rachis browning and dehydration.

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.

Table Grapes

Grape (Vitis vinifera) storage requires stringent control of gray mold caused by Botrytis cinerea. The commercial practice is dependent on sulfur dioxide (SO2) as a fumigant, which is applied by various means with well-known advantages and disadvantages. Many alternative technologies were developed over the years, most of them with limited efficacy or applicability. Modified atmosphere of table grapes suffers from a narrow threshold between control of gray mold and damage to the berries and stems due to high level of carbon dioxide (CO2) within the film-enclosed package. We demonstrated in the past that dipping table grapes in ethanol after harvest has a very pronounced effect on prevention of decay. However, ethanol does not leave a protective residue within the grapes, so it is not expected to prevent latent infections from developing decay nests during prolonged storage. However, if grapes of cultivar Superior were treated with ethanol and then subjected to a modified atmosphere using plastic films (Xtend), we achieved an additive effect and observed persistent control of gray mold without injury to the grapes. The advantage of this plastic film was mainly in its water conductance, which prevented accumulation of free water that is often the limiting factor in modified atmosphere packaging. This combination results in greater decay control, which is a prerequisite for commercial applicability. If undesired aftertaste did develop within the fruit due to the modified atmosphere, 1 day of exposure to ambient air was sufficient to dissipate it.

Modified atmosphere packaging, Transpiration, Weight loss, Apple Abstract. In the article the modified atmosphere packaging (MAP) of post-harvest apples are developed and evaluated. Firstly, the comparison package box with MAP and without package is developed and applied to make comparison experiments of post-harvest apples during storage of 30 days, 60 days and 90 days. Secondly, the influence of MAP on the transpiration of post-harvest apples is evaluated by comparison experimental studies, the respiration model and the change of water loss for post-harvest apples is analyzed. These results show that, within the initial storage of 20 days the change of water loss of apples with MAP or without package is approximate and almost linear. After 20 days of storage duration, the two cases of water loss have obvious difference, the water loss by transpiration for apples without package still shows linearity and maintain constant transpiration rate, yet the transpiration rate of apples with MAP would gradually decrease. In addition the transpiration of post-harvest apples with MAP can be effectively retarded at high relative humidity, and the post-harvest may maintain better quality and 90 days shelf life at storage condition of constant temperature 5°C and relative humidity 60%.
