THE STATUE OF LIBERTY Give me your tired, your poor, Your huddled masses yearning to breathe free he wretched refuse of your teeming shore Send these, the homeless, tempest-tossed to me I lift my lamp beside the golden door

During recent years there has been an explosive growth in the market for fresh prepared fruit and vegetable (i.e. produceproducts. The main driving force for this market growth is the increasing consumer demand for fresh, healthy, convenient and additive-free prepared product items. However, fresh prepared produce items are highly perishable and prone to the major spoilage mechanisms of enzymic discoloration, moisture loss and microbial growth. Good manufacturing and handling practices along with the appropriate use of modified atmosphere packaging(mp)are relatively effective at inhibiting

As we know from the definition, intelligent or smart packaging monitors and gives information about the quality of the packed food. According to Huis in't give Veld (1996) the changes taking place in the fresh food product can be categorised as (i) microbiological growth and metabolism resulting in pH- changes, formation of toxic compounds off-odours, gas and slime formation

Part I Introduction 1 Keys to new product success and failure. 1.1 Food products-the basis of innovation 1.2 Measures of product success and failure 1.3 Key factors in product success . 1.4 Product development process: the basis for success

Product development has been a major activity in the food industry for over 40 years, but only gradually has it developed as a strategic business area and also as an advanced technology. For a long time it was essentially a craft, loosely related to the research and engineering areas in the company. The pressures for product development came very strongly from the needs of the growing supermarkets for a constantly changing, extensive mix of products and for continuous price promotions. So there was the drive for product difference
