Almacenamiento de Trozos de ？ame (Dioscorea rotundata Poir) en Atmósferas Modificadas

in this work storage conditions of chunks yam packed in polymer films with modified atmosphere are analyzed. respiration rate of chunks yam at refrigeration temperature (5 ± 1°c) and room temperature (27 ± 1°c) and different films with modified atmosphere were evaluated. respiration rate at refrigeration temperature was 2.9 ± 0.9 mlc02/kg-h (graphically) and 3.2 ± 1.0 mlc02/kg-h (analytically), and room temperature of 20.1 ± 0.8 mlco2/kg-h (graphically) and 22.4 ± 0.9 mlc02/kg-h (analytically). modified atmosphere packaging of minimally processed chunks yam is not a good alternative. this because the product quality is affected, with shelf life between 6 and10 days.
