壳聚糖对卷烟烟气中低相对分子质量醛类物质的特殊作用

The Special Effect of Chitosan on Decreasing Volatilizable Aldehydes in Smoke from Cigaret

将不同脱乙酰度、不同粒度大小、不同剂量的壳聚糖加入到卷烟滤棒中 ,运用比色法测定烟气中总挥发性脂肪醛类的含量 ,从而得出壳聚糖对主流烟气中总挥发性脂肪醛类物质的降低效果 .结果表明 :3种不同脱乙酰度的壳聚糖对主流烟气中总挥发性脂肪醛类物质的降低效果都很明显 ,尤其是在保证烟气内在品质的前提下 ,加入 3 0mg粒度为 1 0 0目左右、脱乙酰度为 90 %的壳聚糖 ,主流烟气中总挥发性脂肪醛类物质可降低 5 7.1 % .

The effects of a new type additives of chitosan on decreasing volatilizable aldehydes in cigarette smoke were investgated by adding into filter in cigarette and determining the content of volatilizable aldehydes by spectrophotemetric method. The influences of dosage and deacetylation degree (DD) of chitosan on volatilizable aldehydes and quality of cigarette smoke were discussed. The results showed that chitosans with DD of 50%,75%,90% can decrease aldehydes in smoking efficiently, and the content of aldehydes was reduced by 57.1% when 30 mg chitosan with a DD of 90% was applied in filter, but the quality of smoke was barely affacted.
