Food and Drug Administration and many agencies in other countries. The Fifth Edition updates the field, incorporating the definitive monographs of previous editions with completely new material. Each monograph provides a physical description of the substance and its use in foods, lists its purity requirements, describes the appropriate tests to determine compliance, and provides packaging and storage guidelines.

Other features include. The Fifth Edition reflects many of the changes in science and manufacturing since the publication of the Fourth Edition. The FCC receives international recognition by manufacturers, vendors, and users of food chemicals. The Fifth Edition will be a welcome update to food technologists, quality control specialists, research investigators, teachers, students, and others involved in the technical aspects of food safety.
