Formulae for Predicting Gas Exchange of Fresh Produce in Polymeric Film Package

Use of a simple mathematical model to evaluate dipping and MAP effects on aerobic respiration of minimally processed apples

“…To describe the time course during storage of O 2 and CO 2 concentration inside the package during storage, modifying the equations previously derived by Hayakawa, Henig, and Gilbert (1975), the mass balance on these two substances in the package head space is written as follows:…”

The Development of a Model to Describe the Influence of Temperature and Relative Humidity on Respiration Rate of Prickly Pear Cactus Stems in Reduced O2 Conditions

“…Non-linearity in the decline of the atmospheric O 2 level can be indicative of developmentally-dependent changes in the aerobic respiratory rate or the suppression of respiratory activity due to limiting O 2 partial pressures. Several models have described O 2 uptake as a function of O 2 including partial pressures in the range capable of inhibiting the terminal oxidases in the electron transport pathway (Cameron et al, 1994;Hayakawa et al, 1975;Mannapperuma et al, 1989).…”

Modeling the effects of temperature and relative humidity on gas exchange of prickly pear cactus (Opuntia spp.) stems

“…The transport (flux) of gases (O 2 , CO 2 , H 2 O vapor and N 2 ) through the film was modeled based on their diffusion (Fick's first law). Since the diffusion is in solid medium, the application of Henry's law may describe this process as a function of the permeability coefficient and the partial pressure of the gas (Emond, Castaigne, Toupin, & Desilets, 1991;Hayakawa, Hening, & Gilber, 1975;Makino & Hirata, 1997;Zhu, Chu, Wang, & Lencky, 2002):…”
