PLASTIC PACKAGING MODELING: INTERACTIONS WITH FOOD. MODEL AND METHOD TO ESTIMATE THE SHELF LIFE OF OXYGEN-SENSITIVE FOOD PRODUCTS

摘要

A model to estimate the shelf life in oxygen sensitive food products is proposed. The kinetics of oxygen consumption of the food product and the permeation properties of the package are considered. A novel method to characterize the oxygen consumption is discussed. Some results for an oxygen-sensitive product are presented. The model and method proposed are very useful for developing new products and for making decisions about the selection of film and packaging conditions according to the shelf life expectations.
