Abstract: Bananas sealed in Low Density Polyethylene(LDPE) bags with known p er meability coefficient were incubated at different temperatures(10,15,20,25,30℃) until O2 and CO2 levels in the packages reached a steady state. Bananas respira t ion rate was determinded by two methods. One was the Numeral method (NM)and th e other was the traditional sealed container method(TSCM).In addition, the resu lts determined with two methods were compared. The results showed that banana r espi ration rate determined with the TSCM was lower than the one determined with the NM. The difference could be deciphered through respective principles of th e dete rmination method.
