葡萄糖/丙氨酸Maillard反应水溶性高分子产物的规模化合成及其在烟草中的应用

Large-scale Synthesis of Water-soluble Polymeric Product of Glu/Ala Maillard Reaction and its Application in Tobacco

为扩大Maillard水溶性高分子产物的产量,考察了规模化合成葡萄糖(Glu)/丙氨酸(Ala)Maillard水溶性高分子产物的条件包括投料比、加热方式、反应时间、分离方法对产物得率及其在卷烟中的加香效果的影响。结果表明:①适宜的规模化合成条件为:投料比Glu/Ala(摩尔比)=1∶1,NaHCO34%,95℃下反应24～30h,醇析法和喷雾干燥法分离;②规模化产品对卷烟的香气量、杂气、浓度、细腻柔和度、刺激性、余味、回甜等方面都有不同程度的改善,尤其是在香气量、杂气和细腻柔和度方面。醇析法产品对香气的改善更明显,而喷雾干燥法产品对口感的改善效果更好。

In order to industrialize the production of water-soluble Maillard reaction polymeric product,the synthetic conditions influencing the product of glucose/alanine （ Glu/Ala） Maillard reaction were investigated, including proportion of input materials,heating mode,reaction time and isolation method. The results showed that： 1） the appropriate synthetic conditions were： input ratio of Glu/Ala 1∶ 1 （ molar ratio） ,NaHCO3 4% , reaction temperature 95 ℃,reaction time 24 to 30 hours,and product isolation by alcohol precipitation or spray-drying. 2） The aroma quantity,offensive odor,smoke concentration,smoothness,irritancy,aftertaste of cigarette smoke were improved to different degrees by adding the synthetic product,particularly in aroma quantity,offensive odor,and smoothness. The smoking aroma was more significantly improved by an alcohol precipitation product,while taste was more obviously enhanced by a spray-drying product.
