摘要
研究考察了两种烟用三乙酸甘油酯在不同温度(45℃、22℃、4℃)条件下189天长期储存过程中的酸度变化。结果发现,三乙酸甘油酯S1在各温度条件下酸度均有明显提升,其酸度最高达到0.302%,是标准规定限值的30倍,而三乙酸甘油酯S2则能够在各温度条件下均保持稳定。因此,储存温度是三乙酸甘油酯酸度提升的必要但非充分条件,其本身的杂质成分可能是影响储存稳定性的重要因素。
The acidity changes of two types of triacetin used for cigarettes was investigated during 189 days long-term storage at different temperatures(45℃,22℃,4℃).As a result,it was found that the acidity of triacetin S1 increased significantly under different temperature conditions,with the highest acidity reaching 0.302%,which is 30 times the standard limit.Meanwhile,triacetin S2 remained stable under all temperature conditions.Therefore,storage temperature is a necessary but not sufficient condition for increasing the acidity of triacetin,and its inherent impurities may be an important factor affecting storage stability.
