Description

Unique in its review of modern analytical approaches to vitamin fortification, this book emphasizes fast, sensitive, and accurate methods, along with assays enabling the detection of various isomers and multiple vitamins. The expert contributors describe the concepts as well as analytical and assay methods to study fortification, along with applications to create better and safer foods. Taking into consideration regulatory matters in the US and EU, they include data on sampling and extraction methods, and discuss the various pros and cons of each. As a result, readers are able to determine which type of analysis method is best suited for added vitamins. A practical guide for food chemists and technologists, as well as analytical laboratories and biochemists.
