What Is Food Science?
Food science applies fundamental sciences like chemistry and biology to the study of food and food systems. It examines food's physical, chemical, and biological characteristics to understand its nature, deterioration causes, and processing principles. The goal is to improve foods for consumers in areas such as safety, nutrition, sustainability, and availability.
Sub-disciplines of Food Science
Specializations within food science include food chemistry, food microbiology, food engineering, and sensory analysis, among others. Food chemistry studies the chemical processes in food, food microbiology examines microorganisms in food, food engineering focuses on industrial processes, and sensory analysis looks at how consumers perceive food.
Beyond the Lab: Related Fields of Study
Other disciplines explore the connection between food, human health, and culture.
Nutritional Science and Dietetics
Nutritional science investigates nutrients, their use by the body, and the link between diet, health, and disease. It aims to improve health through understanding food's bodily interactions. Dietetics uses nutritional science to manage health and prevent disease with personalized dietary plans.
The Art and Culture of Gastronomy
Gastronomy examines the relationship between food and culture, the art of food preparation and service, and culinary styles. It delves into the history and social customs of food. Molecular gastronomy is a related area studying the physical and chemical changes in cooking.
Food Science vs. Related Disciplines: A Comparison
Below is a comparison highlighting the different focuses of food science, nutritional science, and gastronomy.
| Feature | Food Science | Nutritional Science | Gastronomy |
