History

There are many branches of food science

, all of which study different aspects of food such as safety, microbiology, preservation, chemistry, engineering, physics and the like. Until the advent of molecular gastronomy, there was no formal scientific discipline dedicated to studying the processes in regular cooking as done in the home or in a restaurant. The aforementioned have mostly been concerned with industrial food production and while the disciplines may overlap with each other to varying degrees, they are considered separate areas of investigation.

Though many disparate examples of the scientific investigation of cooking exist throughout history, the creation of the discipline of molecular gastronomy was intended to bring together what had previously been fragmented and isolated investigation into the chemical and physical processes of cooking into an organized discipline within food science to address what the other disciplines within food science either do not cover, or cover in a manner intended for scientists rather than cooks. These mere investigations into the scientific process of cooking have unintentionally evolved into a revolutionary epicurean practice that is now prominent in today's culinary world.

The term "Molecular and Physical Gastronomy" was coined in 1992 by Hungarian physicist Nicholas Kurti

 became the co-organizers of the workshops, though McGee stepped down after the first meeting in 1992.

Up until 2001, The International Workshop on Molecular Gastronomy "N. Kurti" (IWMG) was named the "International Workshops of Molecular and Physical Gastronomy" (IWMPG). The first meeting was held in 1992 and the meetings have continued every few years thereafter until the most recent in 2004. Each meeting encompassed an overall theme broken down into multiple sessions over the course of a few days.

The focus of the workshops each year were as follows:
  • 1992 - First Meeting
  • 1995 - Sauces, or dishes made from them
  • 1997 - Heat in cooking
  • 1999 - Food flavors - how to get them, how to distribute them, how to keep them
  • 2001 - Textures of Food: How to create them?
  • 2004 - Interactions of food and liquids


Examples of sessions within these meetings have included:
  • Chemical Reactions in Cooking
  • Heat Conduction, Convection and Transfer
  • Physical aspects of food/liquid interaction
  • When liquid meets food at low temperature
  • Solubility problems, dispersion, texture/flavour relationship
  • Stability of flavour

 has existed for many years. Kurti and This acknowledged this fact and though they decided that a new, organized and specific discipline should be created within food science that investigated the processes in regular cooking (as food science was primarily concerned with the nutritional properties of food and developing methods to process food on an industrial scale), there are several notable examples throughout history of investigations into the science of everyday cooking recorded as far as back to 18th century.

 Associate Professor of Home Economics Isabel T Noble. In the foreword of the 346 page book the authors state that, “The main purpose of this book is to give an understanding of the chemical principles upon which good practices in food preparation and preservation are based.”

The book includes chapters such as "The Chemistry of Milk", "The Chemistry of Baking Powders and Their Use in Baking", "The Chemistry of Vegetable Cookery" and "Determination of Hydrogen Ion Concentration" and contains numerous illustrations of lab experiments including such things as a Distillation Apparatus for Vegetable Samples and a Pipette for Determining the Relative Viscosity of Pectin Solutions. The professors had previously published The Hows and Whys of Cooking in 1928.

Professor Belle Lowe of Iowa State College (1886–1961):
In 1932 a woman named Belle Lowe, then the professor of Food and Nutrition at Iowa State College, published a book entitled Experimental Cookery: From The Chemical And Physical Standpoint which became a standard textbook for home economics courses across the United States. The book is an exhaustively researched look into the science of everyday cooking referencing hundreds of sources and including many experiments. At a length of over 600 pages with section titles such as “The Relation Of Cookery To Colloidal Chemistry”, “Coagulation Of Proteins”, “The Factors Affecting The Viscosity Of Cream And Ice Cream”, “Syneresis

”, “Hydrolysis Of Collagen” and “Changes In Cooked Meat And The Cooking Of Meat”, the volume rivals or exceeds the scope of many other books on the subject, at a much earlier date.

Belle Lowe was born near Utica, Missouri on February 7, 1886. She graduated from Chillicothe High School and then received a teaching certificate (1907) from the Kirksville State Normal School in Kirksville, Missouri. She also received a Ph. B. (1911) and an M.S. (1934) from the University of Chicago. In 1957, Lowe received an honorary Ph.D. from Iowa State College (University). In addition to “Experimental Cookery”, she published numerous articles on the subject of the science of cooking. She died in 1961.

 kept in London used a balance to determine whether fermented meat was lighter than fresh meat. Since then, many scientists have been interested in food and cooking. In particular, the preparation of meat stock—the aqueous solution obtained by thermal processing of animal tissues in water—has been of great interest. It was first mentioned in the fourth century BC by Apicius

Chemists have been interested in meat stock preparation and, more generally, food preparation since the eighteenth century (Lémery, 1705; Geoffrey le Cadet, 1733; Cadet de Vaux, 1818; Darcet, 1830). Antoine-Laurent de Lavoisier is perhaps the most famous among them—in 1783, he studied the processes of stock preparation by measuring density to evaluate quality (Lavoisier, 1783). In reporting the results of his experiments, Lavoisier wrote, "Whenever one considers the most familiar objects, the simplest things, it's impossible not to be surprised to see how our ideas are vague and uncertain, and how, as a consequence, it is important to fix them by experiments and facts" (author's translation).

Objectives

The objectives of molecular gastronomy, as defined by Hervé This are:

Current objectives:

Looking for the mechanisms of culinary transformations and processes (from a chemical and physical point of view) in three areas:
  1. the social phenomena linked to culinary activity
  2. the artistic component of culinary activity
  3. the technical component of culinary activity


Original objectives:

The original fundamental objectives of molecular gastronomy were defined by This in his doctoral dissertation as:
  1. Investigating culinary and gastronomical proverbs, sayings, and old wives' tales
  2. Exploring existing recipes
  3. Introducing new tools, ingredients and methods into the kitchen
  4. Inventing new dishes
  5. Using molecular gastronomy to help the general public understand the contribution of science to society


However, This later recognized points 3, 4 and 5 as being not entirely scientific endeavours (more application of technology and educational), and has since revised the primary objectives of molecular gastronomy.

Examples

Example areas of investigation:
  • How ingredients are changed by different cooking methods
  • How all the senses play their own roles in our appreciation of food
  • The mechanisms of aroma release and the perception of taste and flavor
  • How and why we evolved our particular taste and flavor sense organs and our general food likes and dislikes
  • How cooking methods affect the eventual flavor and texture of food ingredients
  • How new cooking methods might produce improved results of texture and flavor
  • How our brains interpret the signals from all our senses to tell us the "flavor" of food
  • How our enjoyment of food is affected by other influences, our environment, our mood, how it is presented, who prepares it, etc.

As a style of cooking

The term molecular gastronomy was originally intended to refer only to the scientific investigation of cooking, though it has been adopted by a number of people and applied to cooking itself or to describe a style of cuisine.

In the late 1990s and early 2000s, the term started to be used to describe a new style of cooking in which some chefs began to explore new possibilities in the kitchen by embracing science, research, technological advances in equipment and various natural gum

Frustrated with the common mis-classification of their food and cooking as "molecular gastronomy", several chefs often associated with the movement (Ferran Adria of El Bulli, Heston Blumenthal of the Fat Duck, Thomas Keller of the French Laundry and Per Se) have since repudiated the term, releasing a joint statement in 2006 clarifying their approach to cooking, stating that the term "molecular gastronomy" was coined in 1992 for a single workshop that did not influence them, and that the term does not describe any style of cooking.
