不同品种烤烟主要品质和安全性指标分析

On index of main qualities and security in different tobacco varieties

对烤烟RG17、中烟90、K346、G80的C3F烟叶中水溶性糖、钾、总氮、烟碱、石油醚提取物、总挥发酸和总挥发碱等品质指标和烟气焦油、稠环芳烃化合物等安全指标进行分析.结果表明:K346的烟碱、石油醚提取物、总挥发碱含量相对较高,RG17的钾含量相对较高,G80的总挥发酸含量较高,而总氮含量相对较低.焦油释放量较高的品种为K346,但该品种苯并[α]蒽、Chrysene、苯并[α]芘3种稠环芳烃含量最低;中烟90的焦油释放量虽然较低,但其稠环芳烃化合物含量最高.

Indexes of main qualities such as soluble sugar, potassium, total nitrogen, nicotine, petroleum ether extract, total volatile acid and alkali, and security indexes of the tar and polynuclear aromatic hydrocarbone（PAHs）were analyzed in the flue-cured tobacco leaves of four varieties, RG 17, Zhongyan 90, K346 and G80. The results showed that the content of nicotine, petroleum ether extract and total volatile alkali in K346, potassium in RG17 was higher. Total volatile acid in G80 was also higher but its content of total nitrogen was lower. The tar delivery of K346 came in the highest but its content of three PAHs, benzo[α]anthracene, chrysene and benzo[α]pyrene, came in the least. On the contrary, the tar delivery of Zhongyan 90 ranked in the least but its content PAHs reached the highest compared to other varieties.
