Food is made of chemicals. To the food manufacturer, these chemicals are all potentially significant, as they determine the nutritional value, eating properties and suitability for use in particular products and processes. This book explains, to those without expertise in food chemistry, some of the basics of food chemical composition. Adopting a strong industrial slant, the book uses examples from food manufacturing and the industry-consumer interface to put food composition in context, considering how it relates to wider issues like safety assurance, traceability, product development and labelling. Selected examples are used to illustrate specific points that often get overlooked in discussions of the chemicals that are either natural to foods or used in preservation and processing. Industrialists and students alike will welcome this book as an aid to understanding the importance of food composition. This book is published in association with CCFRA.

Since the 1980s the bird life of the Cotswolds has seen significant changes, many of them subtle but some spectacular. This beautifully illustrated and extensively researched book, the product of five years' field work exposes these changes with the aid of simple and clear colour maps which give not only a detailed but easily understood picture of the breeding distributions of bird species in the area today, but also a comparison with 20 years ago. The maps are accompanied by descriptive accounts for each species, often containing fascinating local information. The book discusses the relative difficulties of surveying the different species, which will be of help to others undertaking the same task elsewhere. It is richly illustrated by colour photographs of the birds and their habitats. Its easy style and clarity will make this book of great interest not only to ornithologists, but to everyone with a concern for the natural environment of the Cotswolds, and to anyone planning a visit to this Area of Outstanding Natural Beauty.
