Question

A certain spice is known to have the oxygen tolerance limit of 50 ppm. Estimate the shelf life of the vacuum packed spice. Product weight is 250 g and initial oxygen concentration inside the package is assumed as zero. The package surface area is 444 cm2. The package film has structure of 40 um PET/10 um PVDC/15 um LDPE. 02 permeability coefficient of PET, PVDC and LDPE are 0.144, 0.035 and 36.1 cm3(STP)umcm-2day latm-1 respectively. Assumption: Changes in partial pressure between inside and outside of film is 0.21 atm.
