Abstract:
Grapes intended for storage of a few weeks or longer are stored at 0 °C in boxes with a dual release SO2 generating pad (quick release plus a slow release phase). This method can prevent decay caused by Botrytis cinerea for a number of weeks, but the level of SO2 surrounding the grapes falls to below 1 μL L-1 after 60-80 d [Lichter, A., Zutahy, Y., Kaplunov, T., Lurie, S., 2008]. Evaluation of table grape storage in boxes with sulfur dioxide releasing pads with either an internal plastic liner or external wrap. HortTechnology]. Therefore, other methods are needed for grapes, such as 'Red Globe' that can withstand storage for 4 months or longer without losing eating quality. The SO2 generating pad was enclosed in a plastic laminate with macro-perforation. This additional barrier to water vapor penetration into the pad and SO2 diffusion out of the pad decreased the initial SO2 peak released by the pad and extended the lifetime of the pad threefold. The effect of different diameter of macro-perforation was examined from 3 to 9 mm, and the effect of varying the number of holes in the laminate. Grapes were stored for 3 and 6 months and their quality assessed after 3 d of shelf-life. The optimum laminate was found to be 32 perforations of 6 mm diameter. This pad was tested under commercial storage conditions and the quality of the grapes after storage from 92 to 116 d was assessed compared to storage with regular dual release SO2 pads. Decay as well as SO2 damage was greater in the grapes with dual release pads than the macro-perforated laminated pads. This modification of the SO2 generating pad shows promise as a means of maintaining quality of grapes in extended storage. © 2008 Elsevier B.V. All rights reserved.
