Biacetyl the flavoring that makes margarine taste just like butter is extremely stable at room temperature, however at 200degrees Celsius it undergoes a first-order breakdown with a half-life of 9.0min. An industrial flavor-enhancing process requires that a butter-flavored food be heated briefly at 200 degrees Celsius. Explain how long can the food be heated at this temperature and retain 68% of its butter flavor?
