Patent number: 8534297Abstract: The present invention provides a method of testing moisture retention of tobacco in which dynamic rules on moisture desorption of the cut tobacco in a dry environment are investigated by using a dynamic vapor sorption system and has found that a dry basis moisture content at an earlier stage of moisture desorption of the cut tobacco has a preferred linear correlation with a square root of time. A linear fitting for t0.5 is made by using values of a dry basis moisture content Mt at a time point t, and a rate constant k is obtained from a slop of the obtained straight line and used as a reference of testing the moisture retention of tobacco. The method can also be used to investigate the moisture retention of tobacco and filter humectants of cigarettes. In comparison with the conventional method, the method is convenient and applicable, and has a short testing period, a high degree of automation, preferred accuracy and preferred reproducibility, etc.Type: GrantFiled: December 16, 2010Date of Patent: September 17, 2013Assignee: Shanghai Tobacco Group Co., Ltd.Inventors: Da Wu, Guoqiang Zong, Chaoying Chen, Baizhan Liu
