About This Volume
Fermentation is one of humanity’s oldest technologies, yet it remains surprisingly misunderstood. Long before bacteria, yeasts and fungi could be observed beneath a microscope, people had already learned to work with them.
Volume I establishes the foundations of The Food Caravan. It explores fermentation as the controlled transformation of food through the activity of microorganisms and the enzymes they produce — a process that favours particular organisms while making the environment increasingly unsuitable for many associated with spoilage.
It provides the framework for understanding the foods and traditions encountered throughout the rest of the collection: how microorganisms and enzymes transform food, how the major fermentation pathways differ and overlap, how processing affects whether a ferment remains biologically active, how salt guides microbial conditions, and what current evidence allows us to say about fermentation and human health.
In these pages
What You’ll Explore
- What fermentation actually is — controlled transformation rather than decay
- Ancient knowledge that long preceded modern science
- Microorganisms as the living workforce, and enzymes as the drivers of transformation
- Fermentation as a living ecosystem
- The six families of fermentation, from lactic acid to mixed and boundary ferments
- Living, spent and never-fermented foods — and how to read a food label critically
- Salt as the invisible architect of fermentation
- Fermentation and human health: what the evidence supports, and where caution is appropriate

About the author
Marcia George
Marcia George is an independent researcher, educator and writer whose work explores the science, history, culture and living traditions of fermentation.
Her research encompasses microbial ecology, traditional food preservation, culinary heritage, fermentation science, global food cultures, and the relationships between food, health and human civilisation. Drawing together knowledge from different cultures and disciplines, she seeks to present fermentation simultaneously as a biological process and a shared human story.
