Abstract: Cuisine is far more than just a feast for the taste buds — it represents a fascinating stage where physical chemistry principles come to life. When we savor the color, aroma and flavor of food, we are actually experiencing intricate and sophisticated chemical transformations. To thoroughly explore the physical chemistry behind these gastronomic experiences, this article investigates several key aspects: how taste perception emerges from neural-molecular interactions, the subtle changes occurring during food storage, and the remarkable transformations of ingredients during cooking processes. Through these analyses, we reveal the fundamental principles governing various physical changes in food processing and preservation. Our ultimate goal is to help readers develop stronger capabilities in comprehensively analyzing, predicting and simulating complex food engineering challenges.
