The publication of this book has been perfectly timed to serve the needs of a rapidly expanding industry. Frozen foods have shed their associations with low quality convenience food and freezing is now recognised as one of the safest and most nutritionally valuable ways to store food. Quality is a fundamental competitive advantage. However, the quality of frozen foods is dependent upon the strength or weakness of each link in the supply chain. This book examines the key quality factors at each stage in the frozen food supply chain, from raw material selection through processing and storage to retail display. Managing frozen foods is a unique overview of this entire industry and provides frozen food manufacturers, distributors and retailers with:
