Abstract: The shelf-life of drum-dried high lysine sweet corn pulp (flakes) was investigated by chemical analysis (peroxide and acidity index), nutritional evaluation (PER and apparent digestibility of protein) and sensory evaluation (quantitative descriptive analysis) at 0, 60, 120, 180, 240 and 300 days of storage. 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 1.50 g m-2 day-1 and a thickness of 64 μm, 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. © 1991.
