Glc-Pro Maillard Reaction Model and Application of Their Products in Tobacco Flavoring
In order to obtain the distinctive tobacco flavor,using Glc-Pro Maillard reaction model system,the influences of re-action time,reaction temperature,pH and ethanol volume fraction in solvent on the UV-visible absorbance,volatile compo-nents and flavoring effects were investigated by orthogonal experiment,and the suitable reaction conditions were confirmed. The results showed that the influence degree of each factor on the product’s UV-visible absorbance was pH > reaction time >reaction temperature > ethanol volume fraction;33 kinds of volatile components were identified by GC-MS,most of them had impor-tant contributions to smell of products;sensory evaluation showed that the products generated under the conditions of reaction tempera-ture 105 ℃ ,reaction time 4 h,pH 10 and ethanol volume fraction 40% could improve flavor quality and taste of cigarettes,and de-crease irritation. This study showed that Glc-Pro Maillard reaction products had distinct value in tobacco flavoring.
