Joseph explains that “the main three reaction stages happening during roasting are the drying, browning (Maillard reaction, caramelization) and Development (from first crack.)” Maillard is the chemical reaction between amino acids and reducing sugars and is where many of the main flavor compounds are formed.

What happens during roasting : Roasting is a process of heating a sulfide ore to a high temperature in the presence of air. It is a step in the processing of certain ores. More specifically, roasting is often a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s).
