Plate of sushi rolls with salmon, vegetables, and rice wrapped in seaweed, served with chopsticks and a small bowl of soy sauce on a wooden table. — gastronomy A common rice dish of Japanese cooking is sushi. To make a type known as *maki-zushi*, a sheet of seaweed is spread with rice flavored with vinegar. Seafood or vegetables and garnishes are then placed on top. Finally, the whole sheet is rolled into a cylinder and sliced.

Molecular gastronomy is a scientific discipline dedicated to investigating the physical and chemical transformations that occur during culinary processes. Unlike traditional food science, which historically focused on the chemical composition of ingredients and industrial production, molecular gastronomy examines the mechanisms behind phenomena in domestic and restaurant cooking—such as why a soufflé swells or why mayonnaise becomes firm.1

To study these changes, the field employs a structured approach:
* Modeling Recipes: Researchers create models of culinary definitions to understand the objectives of specific preparations.2
* Testing Culinary Precisions: The discipline collects and tests the technical details of recipes to verify their scientific basis.2
* Scientific Exploration: By applying principles of chemistry, physics, and biology, researchers analyze how ingredients interact and change state.12
* Formalism: Tools like the "disperse systems formalism" (DSF) are used to describe the organization and material of food, allowing for a systematic study of transformations in isolation or within solutions like stocks and broths.2

Ultimately, this research seeks to replace anecdotal tradition with objective knowledge, providing a scientific foundation for understanding how food behaves under various culinary conditions.1
