In the later part of the 20th century, the United States experienced a remarkable surge in public interest toward medicinal and aromatic crops and this trend continues. This consumer interest helped create a significant demand for plants with culinary and medicinal applications as the public
discovers their benefits for a wide range of applications. Consequently, this consumer call has generated a huge demand on farmers, but has also provided opportunities for new agricultural crops to support both fresh and dry raw material markets. Processing raw materials for end use by consumers
introduces even more variables at all levels from harvesting to final desired product. Maintaining quality and authenticity throughout this process has inspired farmers, processing facilities, and regulatory agencies to adopt new practices and new laws to maintain safety and quality. Maintaining
this quality and authenticity is often made possible using analytical methods for quality control, which subsequently triggered a demand for both regulatory agencies and scientists throughout the world. For aforementioned reasons, it is imperative that scientists continue to explore related topics
from the field to the final consumer product. This book touches on many of the issues currently being addressed by scientists working to produce the desired consumer product while maintaining authenticity and quality and environmental stewardship.
