✦ Synopsis
Perforations or polymeric membranes are n o t capable of simultaneously providing optimum O2 and C02 levels f o r many fruits and vegetables contained i n modified atmosphere packaging. However, combining these t w o gas transfer devices, either in series or in parallel, can provide t h e required gas selectivities t o create optimal modified atmosphere conditions. A methodology f o r determining t h e perforation and membrane surface areas f o r individual and combined systems is described. Gradient diagrams are used to calculate t h e optimum system selectivity, Ap02 and ApC02. These values can be used t o select the appropriate gas exchange devices and t o determine the appropriate perforation and membrane surface area.
