History of Banh Mi

Banh Mi is a type of sandwich that originated in Vietnam and has become increasingly popular around the world, particularly in the United States, France, and Australia. The word “banh mi” itself refers to the bread used in the sandwich, which is a long French baguette made with rice flour instead of wheat flour. However, the filling of the sandwich is what really sets Banh Mi apart.

The history of Banh Mi dates back to the mid-19th century when Vietnam was a colony of France. During this time, the French introduced their famous baguette to the Vietnamese, but due to the limited availability of wheat flour, the Vietnamese bakers started using rice flour in their bread-making, resulting in a lighter and crispier texture. In addition, they added local ingredients such as rice vinegar and sugar to the dough to give it a unique flavor.

The science behind the smell of Banh Mi

One of the key contributors to the smell of Banh Mi is the bread or baguette itself. Bread is made up of carbohydrates, proteins, and lipids, which undergo various chemical reactions during the baking process. These reactions produce volatile compounds such as aldehydes, ketones, and esters, which are responsible for the bread’s distinctive aroma. The crust of the bread is particularly rich in these compounds, which are released when the bread is toasted, adding a deep and savory aroma to the sandwich.
