Efficiency of oxygen: absorbing sachets in different relative humidities and temperatures Ciência e Agrotecnologia
Cruz,Renato Souza; Soares,Nilda de Fátima Ferreira; Andrade,Nélio José de.
The main objective of this work was to evaluate the efficiency of oxygen - absorbing sachets at relative humidity of 75%, 80% and 85% and different temperatures, 10±2 ºC and 25±2 ºC. The experiment consisted in determining the O2 absorption under these conditions. A sachet was placed in desiccators with an internal air homogenization system. Aliquots of air were removed at pre-established time intervals and analyzed for oxygen content. The results showed that oxygen absorption by the sachet increased as the relative humidity increased for both temperature. Therefore the oxygen - absorbing sachets were most active under 25±2ºC and 85% relative humidity. At ambient condition (25±2ºC/75%RH) the rate of oxygen absorbed was 50 mL/day and 18,5 mL/day for 10±2ºC....
