l—L-丙氨酸-l-脱氧-D-果糖的合成及在卷烟中的应用

为进一步研究Maillard反应，以丙氨酸、葡萄糖为原料．在甲醇甘油体系中加入一定催化剂进行反应．经分离纯化得到Maillard反应中间体。再运用IR、MS、NMR进行了结构表征，并将这一产物加入卷烟中进行评吸。结果表明：这一单一产物为目标化合物，即1-L-丙氨酸-1-脱氧-D果糖（ADF），其产率为62．7％；ADF在卷烟中具有增浓、增香、减少杂气、改善余味等作用．可以提高卷烟感官质量。

Synthesis of l-I,-Alanine-l-deoxy-D-fructose and its Application in Cigarette

In order to further study on Maitlard reaction, the synthesis of the Maillard reaction intermediate was studied in mixture of anhydrous methanol and glycerol system, using alanine and glucose as raw materials. The Maillard reaction interme diate was received after separation and purification. The structure of purified product was identified by IR, MS, NMR and so on. The cigarette applied with simplex product was evaluated by experts of panel test. The results showed that ： the synthesed compound is the target product. It is 1 L-alanine-l-deoxy-D-fructose（ADF）, and its yield is 62.7%. The sensory evaluation showed that the ADF could enhance the aroma of smoke, reduce the offensive odor and improve the aftertaste.
