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.

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%.

The effect of film perforation on gas content during modified atmosphere packaging of strawberry fruit was studied. Camarosa strawberries were refrigerated at 2 °C, and wrapped with polypropy lene (PP) film with perforations of 1 and 2 mm diameter. Fruits were held at 2 °C during three days, simulating refrigerated transport, and then at 20 °C for four days to simulate retail display tempera tures. Perforation degree affected final gas contents inside the packages, ranging from 5.68-25.96% CO2 and from 4.84-15.69% O2 on day 7. Different gas content profiles were found among packages with similar perforated surface but distinct diameter perforations, which could infer a perforation edge effect on gas exchange. Neither a CO, stratification effect nor a gas exchange site effect were observed for this kind of perforation-mediated modified atmosphere packaging of strawberries.
