For more than a century, national and international governing bodies have had some involvement in regulating the quality and safety of food during production and delivery. Since the beginnings of this modern food regulation in the early 20th century, the way that food is produced, packaged
and distributed has changed drastically. It is difficult to determine if technological advances in the areas of polymer science, refrigeration, and transportation have driven the globalization of the food supply or if the food industry has drawn from these technologies to satisfy consumer's desire
and need.

Ensuring the safety of food requires a complex and ever-changing set of interactions between producers, distributors, consumers and regulators. As advances are made in packaging and food additives, as food distributions systems evolve to meet consumer needs, or as these respond to environmental and
population changes, adjustments to regulatory systems may become necessary. Analytical, environmental and materials chemistry can often play important roles in responding to these changes and in continuing to help with the improvement of food safety and security. These five co-editors bring their
respective expertise to the subject of the food system and the chemical advancements behind it.
