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.
