The first edition of this book proved to be of practical value both to food
manufacturers using natural colorants as important industrial ingredients, to
food colorant producers and to those at research and academic institutions requiring
a thorough treatment of the subject with extensive references.
Features of this second edition:
- The applied aspects have been enhanced with two new chapters on the role of
biotechnology in the production of colorants, and on safety aspects
- All the other chapters have been extensively revised and updated resulting in an
expansion of the text to incorporate much new material
- Color plates have been added to illustrate the major pigments of interest to the food industry
