摘　　要：为寻找新型烟草保润剂,研究了不同于传统多羟基保润剂的乳酸和乳酸盐溶液对烟丝保润性能的影响。以丙二醇为对照,以烟丝含水率比值(实时含水率与初始含水率比值)为指标对乳酸和乳酸钠的物理保润性能进行评价,并以卷烟感官品质舒适度和常规烟气成分安全性验证了其在卷烟中的应用效果。结果表明:在RH40%条件下,乳酸和乳酸钠的保润性能显著优于丙二醇(P<0.05),同时在卷烟烟气舒适性提升方面也表现出优势,但在RH75%条件下,防潮效果差异不显著;对不同乳酸盐的保润性能分析认为,在RH40%条件下,乳酸锂和乳酸钾的保润效果显著优于乳酸钠(P<0.05),在RH75%条件下,乳酸钾的保润效果显著优于乳酸锂和乳酸钠(P<0.05)。Effect of lactic acid solution and lactate solution used on tobacco was studied with the objective to find new type of humectants. Compared with propylene glycol （PG） , moisture retention capacities were evaluated by using water ratio in tobaccos. Results showed that moisture retention capacities of lactic acid and lactate were higher than that of PG under condition of RH40% , and smoking comfort was obtained. No significant differences were detected in moisture retention capacities of lactic acid, lactate and PG under condition of RH75%. Additionally, lithium lactate and potassium lactate showed better moisture retention capacities than that of sodium lactate （ P 〈 0.05 ） under condition of RH40% , while potassium lactate was the best under condition of RH75% （P 〈0.05）.
