Nuclear Magnetic Resonance (NMR) has emerged as a versatile and powerful analytical tool for investigating the molecular composition, structure, and dynamics of various food components. This chapter discusses the fundamental principles of NMR spectroscopy and its relevance to food analysis. It delves into the specific applications of NMR in studying food components like lipids, proteins, and carbohydrates. Furthermore, the chapter highlights the role of NMR in the characterization, authentication, and detection of adulteration of individual food products like honey, meat, dairy, fruits, and vegetables. Overall, this chapter provides a comprehensive overview of the significant contributions of NMR to the field of food science and underscores its importance in addressing critical issues related to food composition analysis and authenticity.
