Designed primarily for the non-Food Science major, this textbook presents principles of food science for the nutrition, dietetics, hospitality, and culinary arts student enrolled in an introductory food science course. For this second edition the authors have expanded the concepts relating to material in all chapters, including quality, gums, organic food, irradiation, biotechnology, sugar substitutes, fat replacers, packaging, health claims, and dietary guidelines. There is also a new chapter dedicated to a discussion on emulsification and foams. In addition, the index has been revamped.
