再造烟叶生产过程中存贮条件对浓缩液品质的影响

Effect of storage conditions on quality of concentrate during reconstituted tobacco production

为探寻造纸法再造烟叶生产过程中浓缩液适宜的存贮条件,考察了不同存贮温度和存贮时间对浓缩液中常规化学成分和致香成分的影响.结果表明:当存贮温度为50℃,存贮时间为4~6 h时,浓缩液中水溶性总糖质量分数在较高的水平,约为10.00%;氯、钾质量分数受存贮温度和存贮时间影响较小;50℃条件下存贮6 h时,浓缩液中各类致香成分的相对含量稳定性较好且稍高于其他温度下的相对含量.综合考虑,适宜的存贮条件为存贮温度50℃,存贮时间5~6 h.

In order to explore the suitable storage conditions of concentrate during reconstituted tobacco production,the effects of different storage temperature and storage time on the routine chemical components and aroma components in the concentrate were investigated.The results showed that when the storage temperature was 50℃and the storage time was 4~6 h,the mass fraction of water-soluble total sugar in the concentrate was at a high level,about 10.00%;the mass fraction of chlorine and potassium was less affected by storage temperature and storage time.When the concentrate was stored at 50℃for 6 h,the relative content of all kinds of aroma components in the concentrate was stable and slightly higher than that of the concentrate at other temperatures.The suitable storage conditions were that storage temperature was 50℃and storage time was 5~6 h.
