What is food chemistry?

The study of the chemical components, properties, and reactions of food.

Who is considered the father of modern food chemistry?

Justus von Liebig, a German chemist, is credited with laying the foundation for modern food chemistry through his research on the composition of food and its relationship to nutrition.

Who introduced the concept of vitamins in nutrition?

Casimir Funk, a Polish biochemist, introduced the concept of vitamins in nutrition, proposing that these essential organic compounds are required for health and well-being.

What is the primary function of carbohydrates in the human body?

Carbohydrates provide energy to the body through their breakdown into glucose, which is a primary source of fuel for cells.

The Maillard reaction primarily involves which two components?

The Maillard reaction, a complex series of reactions that occurs during cooking, primarily involves the interaction of carbohydrates, particularly sugars, with amino acids, which are the building blocks of proteins.
