Modeling for the Modified Atmosphere Packaging of Sapota Fruit
Keywords:Modified atmospheric packaging, extended shelf life, respiration rate, packaging films, permeability of packaging material,
Modified atmospheric packaging utilizes polymeric films with selective permeability for O2 & CO2 and modifies the storage environment by lowering O2 concentration and increasing CO2 concentration. Modeling and design of the Sapota fruit for modified atmosphere storage was done with different packaging materials for the higher shelf life. Based on the respiration rate and permeability of the packaging material the suitable packaging films obtained for the modified atmospheric packaging of Sapota fruit were low density Polyethylene, Polyvinyl chloride, Polypropylene and Polystyrene film. Saran and Polyester films were found to be unsuitable for MAP storage of the Sapota fruit. The developed model provides an effective way for selection of the proper packaging material for Sapota fruit and this model can also be employed for designing packaging films for other fruits and vegetables.
