food chemistry

Food chemistry is concerned with analytical, biochemical, chemical, physical, nutritional, and toxicological aspects of foods and food ingredients. The long-term goals of research in food chemistry are to understand relationships between the structure and functional properties of food molecules and to improve the nutritional, safety and organoleptic aspects of food. See: Definition of Food Chemistry

Brief history of food chemistry

The history of food chemistry dates back to the late 1700s, when many famous chemists were involved in discovering chemicals important in foods. In 1785, for example, Carl Wilhelm Scheele isolated malic acid from apples. In 1813, Sir Humphry Davy published the first book on agricultural and food chemistry, titled Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture, in the United Kingdom. This book served as a foundation for the profession worldwide and went into a fifth edition.

In 1874, the Society of Public Analysts was formed, with the aim of applying analytical methods to benefit the public. Its early experiments were based on bread, milk, and wine. It was also out of concern for the quality of the food supply, mainly food adulteration and contamination issues stemming first from intentional contamination and proceeding later to chemical food additives by the 1950s. The development of colleges and universities worldwide, most notably in the United States, expanded food chemistry through research of dietary substances, most notably the single-grain experiment during 1907-11. Additional research by Harvey W. Wiley at the United States Department of Agriculture during the late nineteenth century played a key role in creation of the United States Food and Drug Administration in 1906. The American Chemical Society established their Agricultural and Food Chemistry Division in 1908, and the Institute of Food Technologists established their Food Chemistry Division in 1995.

Research

Students of food chemistry must have a strong background in the basic sciences and should specialize in one or more of the following minor areas: organic chemistry, biochemistry, nutritional biochemistry, physical chemistry, toxicology, analytical chemistry, and chemical engineering.

Opportunities for research projects in food chemistry include structure/function relationships in food molecules (rheology, emulsions, foams, gels); computer modeling of food molecules; effects of processing, fortification, and packaging on nutritional quality of foods; food toxicology; and flavor chemistry of fruits and vegetables.
