This book comprehensively covers all aspects of the migration of additives into food, giving detailed information on the analytical determination of the additives in various plastics. While the primary focus is practical and results-oriented, the chapter on additive migration theory is quite extensive, and offers a basic understanding of the principles and phenomena underlying the migration process.

From the Preface: “...The analysis of aqueous or fatty foods, beverages, food simulent liquids, pharmaceuticals and cosmetics which have been contacted with plastics either in extraction tests or during the shelf life of a packaged commodity presents many fascinating and all too difficult analytical problems. Thus, the substance to be determined usually occurs at extremely low concentrations and in complex matrix and several extracted substances may be present in the extraction liquid with mutually interfering effects on the analysis. For example, the extract of a polystyrene may contain an antioxidant, an ultraviolet stabiliser, antistatic agent, mineral oil and plasticiser...”

Target Audience: Scientists, technologists, toxicologists, product and packaging managers, and regulators concerned with food packaging.
