不同干燥方式对烟用细菌纤维素结构及挥发性香味成分的影响
Effects of different drying methods on structure and volatile components of tobacco bacterial cellulose
-
摘要: 以烟草废弃物制备的细菌纤维素为原料,利用全自动测色色差计、场发射扫描电子显微镜、同步热分析仪等对经自然干燥(NAD)、热风干燥(HAD)、真空冷冻干燥(VFD)、-20℃预冻-真空冷冻干燥(VFD-20)、-80℃预冻-真空冷冻干燥(VFD-80)和液氮预冻-真空冷冻干燥(VFD-FLN)处理后的细菌纤维素进行形貌与结构表征,利用蒸馏萃取-气质联用法分析不同干燥方式对烟用细菌纤维素香味成分的影响。结果表明:经VFD-FLN处理的细菌纤维素在原有三维网状结构基础上能较好地保持纤维长度;经VFD、VFD-20和VFD-80处理的细菌纤维素的三维空间结构保持较好,但纤维长度变短;经NAD和HAD处理的细菌纤维素空间结构被破坏,导致其复水率和溶胀率最小。经NAD处理的细菌纤维素色泽保留情况最好且其挥发性香味成分主要为酸性物质,相对含量高达97.93%;经VFD处理的细菌纤维素中挥发性香味成分相对含量次之,主要为类胡萝卜素降解产物、萜类化合物降解产物和苯丙氨酸类降解产物;HAD的干燥速度最快,但经其处理的细菌纤维素中挥发性香味成分相对含量最低。Abstract: With prepared from tobacco waste as material, natural drying (NAD), hot air drying (HAD), vacuum freeze drying (VFD), -20℃ pre-freeze-vacuum freeze drying (VFD-20), -80℃ pre-freeze-vacuum freeze drying (VFD-80) and liquid nitrogen pre-freeze-vacuum freeze drying (VFD-FLN) were adopted to dry BC pellicles. The physical properties of dried BC pellicles were analyzed by colorimeter, FESEM and thermogravimetry. Then the aroma components of BC were analyzed by simultaneous distillation-extraction and GC-MS. The results showed that VFD-FLN could keep the fiber length on the basis of the original three-dimensional reticular structure of BC. VFD, VFD-20 and VFD-80 kept the three-dimensional spatial structure of BC better, but the fiber length became shorter. NAD and HAD destroyed the spatial structure, resulting in the lowest rehydration rate and swelling rate. The color retention of BC treated by NAD was the best, and the volatile aroma components of BC were mainly acidic substances, the relative content of which was 97.93%. The content of aroma components after VFD was only second to NAD. The aroma components mainly included carotenoid degradation products, terpene degradation products and phenylalanine degradation products. The drying speed of HAD was the fastest, but the content of aroma components was the least.
