为克服传统保润剂丙二醇在加热烟草制品中吸湿性过强的缺点,制备了一种新型保润剂丙二醇吡咯酯,并利用热重-微商热重-差示扫描量热法、热裂解气相色谱/质谱和低场核磁共振技术考查其热行为及其在再造烟叶中的保润效果。结果表明:丙二醇吡咯酯的热失重区间为 149。9~400。0℃,在 298。7℃时质量损失率达最大(77。39%);在200℃、300℃和350℃下的主要裂解产物为吡咯酸和丙二醇,其中丙二醇可以起到协调和降低烟气干燥感的作用;在低湿环境下添加丙二醇吡咯酯的再造烟叶丝保润能力高于空白组,但低于丙二醇组;丙二醇组、丙二醇吡咯酯组和空白组中再造烟叶丝内部结合水占比分别为 75%、70%、68%,即丙二醇吡咯酯可以降低再造烟叶丝的强吸湿性,同时保持一定的保润能力。
Preparation of a novel moisturizing agent propylene glycol pyrrolide and its moisturizing effect on reconstructed tobacco leaves
To overcome the disadvantage of strong moisture absorption of traditional moisturizing agent propylene glycol in heated tobacco products,a new type of moisturizing agent propylene glycol pyrrole ester was prepared,and its thermal behavior and moisture retention effect in reconstituted tobacco leaves were investigated by thermo-gravimetric-derivative thermogravimetry-differential scanning calorimetry,pyrolysis gas chromatography/mass spec-trometry and low-field nuclear magnetic resonance imaging.The results showed that:the thermal weight loss inter-val of propylene glycol pyrrole ester was from 149.9℃to 400.0℃,and the maximum weight loss rate 77.39%reached at 298.7℃.Propylene glycol pyrrole ester was subjected to thermal cracking at 200℃,300℃and 350℃,and it mainly could crack and decompose to release pyrrolidic acid and propylene glycol,among which propylene glycol could harmonise and reduce the sense of dryness of the tobacco.The moisture retention ability of reconstituted tobacco leaves added with propylene glycol pyrrole ester in low humidity environment was higher than that of the blank group,but lower than that of the propylene glycol group;The area of bound water inside the reconstituted tobacco leaves in a low humidity environment of propylene glycol group,propylene glycol pyrrole ester group and blank group was 75%,70%,and 68%,respectively.Propylene glycol pyrrole ester could reduce the strong moisture absorption of reconstituted tobacco leaves while maintaining a certain degree of moisture retention.
