Preparation of Flavor with Burnt-sweetness Scent by Simulating Sweet Potato Roasting and its Application to Cigarette

In order to obtain a tobacco flavor with a prominent style by means of roasting sweet potato,the chemical components in flavors prepared with direct or simulated roasting technology were analyzed by GC/MS method on the basis of the aroma generating mechanism of roast sweet potato,and the sensory evaluation was conducted.The results showed that:1) There were more aroma components in the flavors obtained with simulated roasting technology,while retaining the characteristic aroma note substances of direct roasting.2) The obtained roast sweet potato flavors better harmonized with the aroma of Chinese-style flue-cured tobacco,and imparted more distinct aroma and taste characteristics of roast sweet potato to tobacco blend.3) The obtained roast sweet potato flavors had potential application values to the development of 'burnt-sweetness' style cigarettes.
