Beschreibung

Sensory Profiling of Dairy Products In Sensory Profiling of Dairy Products, distinguished dairy technologist Dr John J. Tuohy delivers an expert discussion of advances in the sensory profiling of dairy products, including the physiology of sensory perception, sensory profiling methodology, statistical data analysis and consumer studies. The book covers the sensory profiling of dairy products like fluid milk, yoghurt, a wide range of internationally popular cheese varieties, ice cream, butter, and milkfat products. Beginning with a historical review of the sensory evaluation of dairy products, the book covers recent advances in the practice. The editor has also included resources that profile the sensory attributes of the products most important to the dairy industry: fluid milks, cream and milkfat products, frozen dairy desserts, and a variety of cheeses. Readers will also find: * A thorough introduction to sensory analysis and consumer mindsets and emotions regarding dairy products * Comprehensive explorations of the chemistry, biochemistry and physiology of sensory perception of the flavour and mouthfeel stimuli imparted by dairy products * Practical discussions of the sensory attributes of fat-rich dairy and ethnic Indian products * Fulsome treatments of the sensory profiles of natural and processed cheese varieties Perfect for dairy professionals, regulators, and lawmakers, Sensory Profiling of Dairy Products will also earn a place in the libraries of food marketing professionals, retailers, and culinary practitioners, as well as professors and students with an interest in dairy products.

Preface to the Technical Series

For more than 75 years, the Society of Dairy Technology (SDT) has sought to provide education and training in the dairy field, disseminating knowledge and fostering personal development through symposia, conferences, residential courses, publications and its journal, the International Journal of Dairy Technology (previously published as the Journal of the Society of Dairy Technology).

Recently, there have been significant advances in our understanding of milk systems, probably the most complex natural food available to man. At the same time, improvements in process technology have been accompanied by massive changes in the scale of many processing operations and the manufacture of a wide range of dairy and other related products.

Some years ago, the Society embarked on a project with Wiley to produce a Technical series of dairy‐related books to provide an invaluable source of information for practising dairy scientists and technologists covering the range from small enterprises to modern large‐scale operations. This latest, the sixteenth, volume in the series, on Sensory Profiling of Dairy Products, provides a link between the other titles in the series and covers an aspect of dairy science that is of great importance to all those who work in the industry.

Preface

Globalisation of the international food industry, more extensive foreign travel by the current generations of consumers and access to social media platforms have led to an unprecedented interest in and curiosity about dairy products and new dairy foods. In response, there has been significant diversification of the range of dairy products that consumers have access to, via the mainstream grocery trade, speciality or ethnic food stores, farmers' markets and increasingly online over the internet. The ambition is for this book to be a source of basic sensory information on some important traditional dairy products and new dairy foods from around the world, drawing on the latest scientific and technological knowledge and in a format that is accessible to dairy professionals from across the dairy supply chain including: manufacturing, product development, innovation and marketing, retailing, culinary as well as in regulatory affairs.

Among safe, natural foods, dairy products stand out for the diversity of characteristic sensory properties including: appearance, flavour, aroma, and texture and mouthfeel, found within the category. For centuries, these characteristic sensory attributes of dairy products have been the basis of quality assurance, product innovation and important criteria in the marketing and regulation of national and international trade in dairy products. Advances in biology, physiology, flavour chemistry, texture analysis sensory data analysis, process engineering, as well as a better understanding of the psychology of human behaviour, have all contributed to improvements in sensory methodology, the interpretation of sensory test data and a more objective understanding of the sensory preferences of consumers and strategies to address them.

After a brief historical synopsis of the sensory evaluation of dairy products, the opening chapter deals with a modern psychological approach to understanding consumer attitudes to dairy products and the interpretation of consumer feedback to inform commercial decision‐making. Advances in the physiology of sensory perception are covered in the second chapter with particular reference to dairy product applications. Chapters 3–5 deal essentially with sensory methodology and the analysis of sensory data concerning dairy products.

The core of the book comprises Chapters 6–16, which profile the sensory attributes of products among the most important dairy categories (fluid milks, cream and milkfat products and frozen dairy desserts) but with particular emphasis on representative cheese varieties such as: Cheddar (Chapter 10), Swiss (Chapter 11) and hard Italian cheeses (Chapter 12) while also featuring both well‐known and lesser‐known indigenous cheese varieties from the Middle East (Chapter 8), Pan‐America (Chapter 9) and Iberia (Chapter 13).
