This is the first book to explore the science underlying the concept of "koku", which is central to an understanding of the palatability of food within Japanese cuisine and is attracting increasing interest among food scientists and professionals worldwide. Koku may be defined as the sensation that results from the complexity of the food (i.e., its richness or body), its lingering aftertaste or persistence, and its heartiness in terms of taste, aroma, and texture. A variety of substances have been found to impact significantly on koku, including umami substances, phytosterols, certain aromatic compounds, and kokumi substances. In Koku - Food Science and Physiology, readers will find full explanation of the conceptual aspects and the latest research results on a wide range of topics, including the relevant flavor chemistry and sensory analysis. Written by leading scientists in the field, the book will be a valuable resource for students and researchers in the fields of food chemistry, nutritional science, taste physiology, and neuroscience, as well as for professionals in the food industry.
