The stability and shelf-life of a product is a critical factor in terms of economic feasibility and consumer acceptability. However, food manufacturers experience considerable difficulties in defining and understanding the factors that influence stability over the desired storage period.

This book brings together a range of international experts to assess such issues as the use of sensory, instrumental and accelerated tests to measure shelf-life, the complex range of factors which determine the stability of food, and how these can be used to extend the shelf-life of specific products.
