The colour stability of meat products is influenced by a large number of factors some of biochemical nature, some due to handling during slaughter and processing, and others due to packaging and storage conditions. This chapter focuses on modelling how colour shelf-life is affected by the external factors applied during packaging and storage. However, meat from different sources shows different tendencies to undergo colour deterioration and this variation in internal factors influences the developed models. Therefore some consideration will also be given to discussing how internal factors like

2.1 Introduction: the role of packaging in the food chain Packaging has a significant role in the food supply chain and it is an integral part both of the food processes and the whole food supply chain. Food packaging has to perform several tasks as well as fulfilling many demands and requirements. Traditionally, a food package makes distribution easier. It has protected food from environmental conditions, such as light, oxygen, moisture, microbes, mechanical stresses and dust. Other basic tasks have been to ensure adequate labelling for providing information e.g., to the customer, and a proper convenience to the consumer, e.g., easy opening, reclosable lids and a suitable dosing mechanism. Basic requirements are good marketing properties

The aim of this chapter is to identify the important factors in food product development to be studied in detail in the succeeding chapters. Firstly the different groups of food products are identified as a basis for organising product strategy. Then the published research on the factors in product failure and product success in all types of industries is used to identify the key factors in food product development. This leads into the management of product development at three different levels:
