The specification for the package to control the shelf-life was based on the water vapour permeability rate of the polyethylene film and hygroscopicity of the product. The selected film, with a water vapour permeability rate of 1 .50gmd2 day-’ and a thickness of 64pm, was adequate to guarantee a shelf-life of 6 months under the conditions of storage employed (low light exposure at 23”C), without any indication of deteriorative processes. High peroxide content and sensory quality deterioration, without any change in the nutritional quality of the protein, was detected at 240 days of storage.  aPackaging  aMilho Doce  aProduto desidratado  aShelf-life  aVida-de-prateleira  aWater vapour permeability1 aSGARBIERI, V.
