Conceptual models are descriptions of our understanding of system that are used to shape the implementation of solutions to problems. 58 The quality and quantum of innovation that will occur in development of modified atmosphere packaging (MAP) strongly depends upon the insights gained from robust conceptual models of components of MAP. In this chapter, we outline a number of simple principles about modified atmosphere(MA) systems that we believe will assist industries that apply MA technology to move beyond the rather

The four basic stages in the PD Process are the same for all food product development, but there are significant differences in the activities, techniques and timings for new product development in the primary production, industrial food processing, and food manufacturing industries Primary production's product development is based on either a breeding process from cultivated varieties or capturing a new species from the wild. The development of new plants, animals and fish takes a great deal of time and depends on times of growing and harvesting There can be a general product concept based on perceived consumer or industrial wants and needs
