Caramel, on the other hand, is a sweet confection made by heating sugar slowly to a high temperature. When evaporated milk is turned into caramel, it undergoes a significant transformation, both in terms of its chemical composition and its physical properties.
The Caramelization Process
The process of turning evaporated milk into caramel is essentially a caramelization process. Caramelization is a chemical reaction that occurs when sugars are heated to a high temperature, typically between 338°F and 345°F (170°C and 173°C). This reaction involves the breakdown of sugar molecules into new compounds with distinct flavors, aromas, and colors. In the case of evaporated milk, the lactose (milk sugar) and other sugars present in the milk undergo caramelization when heated.
Chemical Reactions Involved
The caramelization of evaporated milk involves several key chemical reactions:
- Maillard Reaction: This is a non-enzymatic browning reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. In the context of evaporated milk caramelization, the Maillard reaction contributes to the development of the caramel’s flavor and color.
- Caramelization of Sugars: As sugars are heated, they break down into simpler molecules and then recombine into new compounds with characteristic caramel flavors and colors.
- Coalescence of Fat Globules: Evaporated milk contains fat, which plays a crucial role in the texture of the caramel. As the milk is heated, the fat globules coalesce, contributing to the smooth, creamy texture of the caramel.
