“…Previously developed models (Equations ( 8), ( 9) and ( 11)) and a neural network-based model for estimating the ethylene permeance of perforated film are empirical models and would not apply comprehensively to the broad range of experimental data. 20 Thus, the dimensionless correlation is a novel way to determine the permeance of perforated packaging films. The empirical models do not obey the principle of dynamic similarity.…”

“…Techavises and Hikida 15 employed a similar model (Equation (8)) and experimental setup of a cylinder to characterise and model the mass transfer coefficients of O 2 , CO 2 , N 2 and water vapour for different MAP films. The transmission of ethylene gas has been determined using a lumped‐capacity model (Equation (8)) like the transmission of O 2 and CO 2 through perforated packaging materials considering there is no transfer of ethylene through intact films 20

“…It is inversely proportional to the diameter of the perforation. Sonawane et al 20 developed an empirical model (Equation (8)) for determining the ethylene permeance through needle‐perforated films at different temperatures and cooling air velocities over the package.

“…For the laser‐perforated packaging films, Sonawane et al 22 found that the ethylene transmission rate decreased linearly with an increase in film thickness from 20 to 30 μm whereas it increased exponentially with an increase in perforation diameter from 50 to 150 μm. Sonawane et al 20 studied the effect of temperature and cooling air velocity on ethylene permeance. The study suggested that storage temperature influenced ethylene permeance moderately whereas cooling air velocity over the package impacted the ethylene permeance to a little extent.…”

Ethylene accumulation is one of the main causes of rapid deterioration of climacteric fruit and vegetables in a package as ethylene accelerates the ripening process. Modelling the ethylene gas in a package headspace is a promising way to control the ripening process as it provides and optimises the methods to remove ethylene. In this review, the transmission of ethylene through a package, ethylene removal by a scavenger and ethylene accumulation inside the package are discussed with their models. The permeability of packaging material allows ethylene to escape from the package to a little extent. The perforation in packaging material also helps ethylene to depart rapidly from the fruit package which is explained and modelled using Fick's first law of diffusion. The pseudo‐first‐ and second‐order kinetics based on the adsorption phenomena have been used to model the removal of ethylene by a scavenger. The mass balance between the ethylene transmission rate through the package, ethylene production rate by fruit and ethylene removal by scavenger provides the ethylene accumulation which can be helpful for predicting the quality of the fruit inside a package. This study could lead to the development of an active fruit packaging system with the inclusion of ethylene along with oxygen and carbon dioxide for extending the shelf life of fresh commodities in postharvest storage.
