Citrus Processing : Quality Control and Technology

Citrus juices constitute the majority of the fruit juices consumed in the United States and around the world. Along with the rest of the fruit juice industry, they playa major role in the entire food industry as well. In spite of this prominence, few texts have been written on quality control technology; and most of the texts have been written by researchers who may possess great technical skill but generally are less familiar with daily routine quality control problems and con­ cerns than quality control technologists are. On the other hand, quality control technologists and managers generally do not have the time and/or the talent to write books or communicate through scientific literature. The author recognized the need for an updated, comprehensive, and easily understood text on citrus quality control. This text has been designed to be used not only by processors, bottlers, canners, and others involved in the citrus in­ dustry, but it can be of value to instructors and students of citrus technology. Researchers also can find value in the foundations laid down by the text, es­ pecially in regard to the needs and concerns of the processing industry. Also, consultants and marketing personnel will be greatly helped by understanding the concepts of this volume. Persons in related industries also will find many applications that can be easily adapted to their needs.
