Cellulose and other substances will be carbonized to varying degrees. Moisture and carbon dioxide will volatilize. Protein will be converted into enzymes and fats. The remaining substances will combine together to form an oil film layer on the surface of coffee beans. In the process, coffee acids will be generated.
