ANDRADE, Ricardo D; PALACIO, Juan C; PACHECO, Waldir A  y  BETIN, Robert A. Modified Atmosphere Packaging of Chunks Yam (Dioscorea rotundata Poir). Inf. tecnol. [online]. 2012, vol.23, n.4, pp. 65-72. ISSN 0718-0764.  doi: 10.4067/S0718-07642012000400008.

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.
