Özet:
Ongoing efforts to solve problems related to the quality of horticultural commodities "from farm to fork" offer opportunities for research and technological development in modified atmosphere packaging (MAP) of fresh produce. Physiology of fresh produce can be altered with optimum MAP conditions leading to prolonged shelf life. However, maintaining optimum gas conditions and package volume is challenging due to permeation of gases through packaging film and respiration activity of the produce. Innovative modified atmosphere components such as perforated films and active packaging were introduced commercially. With the current clean label trend, consideration of the active food contact materials as additives creates problems from the consumer perspective. To date, active and passive MAP has relied upon dynamics of gas exchange between atmosphere and product through the package. A pressurized polymer insert filled with gas mixture can help maintaining and modifying headspace gas concentrations by offering potentially low cost and effective solution. This work presents the introduction of a permeable insert package component for the packaged fresh produce to keep optimal gas concentrations throughout shelf life. The specific objectives of this work are: 1. Design and pressurize the package insert, 2. Develop a model to predict transient gas conditions within the package and the insert, 3. Validate the model using various fresh produce samples with respect to the respiration intensity. 4. Perform a global sensitivity analysis and uncertainty analysis based on the distribution of varying input parameters, and determine effects of system components and conditions to final package concentrations.
Results of this work can be used to improve the current technology, to find suitable applications under clean label regulations and to predict optimal concentrations when packages are designed with pressurized inserts, as well as to provide a basis for future applications in the packaging with modified conditions.
