Modified atmosphere packaging(map) is widely used for many food products and is now a commercial and economic reality. MAP is common in markets that have a well established and controlled cold chain and that can sustain a high- priced quality product. However, MAP is a mild preservation method and a major concern is that MAP storage may not provide a sufficient level of safety for the extended storage of fresh chilled food products with regard to pathogenic

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

Fresh fish products are usually more perishable than most other foodstuffs due to their high aw, neutral pH, and presence of autolytic enzymes. The spoilage of fish and shellfish results from changes caused by oxidation of lipids, reactions due to activities of the fishes'own enzymes, and the metabolic activities of microorganisms (Ashie et al., 1996). The rate of deterioration is highly temperature dependent and can be inhibited by the use of low storage

Consumer satisfaction is related to fresh product quality. This quality is generally associated with visual appearance, colour being one of the most important aspects in the consumer's purchase decision. The association of certain colours with the acceptance of fruits and vegetables begins early and is maintained through life. For instance, when the red colour of fruit is enhanced, the perceived sweetness level increases. Colour is normally used to determine

Major technological developments in food packaging can introduce many benefits to consumers and food and food-packaging industries, but at the same time they are liable to the introduction of new problems. Although active and intelligent packaging continues to broaden in scope and these new packaging systems are already being successfully applied in the USA, Japan and Australia its penetration in the European

24.1 Introduction: the problem of plastic packaging waste Polymers and plastics are typical materials of the last century and have made a tremendous growth of some hundreds of tons/year at the beginning of the 1930s to more than 150 million tons/year at the end of the 20th century with 220 million tons forecast by 2005. Western Europe will account for 19% of that amount. Today

26.1 Introduction: new packaging techniques and the consumer New packaging techniques promise consumers safe food products that keep their high quality throughout shelf-life. The improved quality has been achieved by applying tailored technological solutions that require highly specialised knowl- edge. From consumers'point of view these new techniques require explanations if food can keep fresh for an unexpected and thereby unnaturally long time

Modified atmosphere (MA)techniques for horticultural products are based on the principle that manipulating or controlling the composition of the surrounding atmosphere affects the metabolism of the packaged product. By creating favourable conditions, quality decay of the product can be inhibited. The different MA techniques come with different levels of control to realise and/or maintain the composition of the atmosphere around the product. Passive MA packaging(MAP)

All engineering, manufacturing, quality and sales efforts are wasted if your transport packaging fails and your customer receives a damaged product'(ISTA).! 25.1 Introduction: the supply chain for perishable foods Food is a perishable product. It is temperature-, moisture-, and time-sensitive, compared to books, automobile parts, and clothes, however they are shipped
