Nanotechnology is a field of science and engineering that deals with the manipulation of matter at the very minute scale. At this scale, materials and devices exhibit unique physical, chemical, and biological properties that differ from those at larger scales. Nanotechnology comprises a broad range of disciplines, including physics, chemistry, biology, materials science, and engineering. It involves the design, fabrication, characterization, and application of nanoscale materials, structures, and devices for various purposes. Nanotechnology has revolutionized the field of food science by offering innovative solutions to challenges related to food safety, quality, and sustainability. Nanomaterials are engineered and applied at the nanoscale to enhance food properties, packaging, and preservation techniques. These systems can monitor food freshness, detect spoilage, and even release antimicrobial agents to extend shelf life. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of nanotechnology and food science. The ever growing need of advanced technology is the reason that has fueled the research in the field of nanotechnology in recent times. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
