新型保润剂丙二醇吡咯酯的制备及其对再造烟叶保润效果研究
Preparation of a novel moisturizing agent propylene glycol pyrrolide and its moisturizing effect on reconstructed tobacco leaves
摘要
Abstract
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.关键词
