  • Publication number: 20150237911
    Abstract: The present invention relates to the field of tobacco, and more particularly to a use of a saline aqueous solution as a hydrated humectant for tobacco stem. The present invention provides a use of a saline aqueous solution as a hydrated humectant for tobacco stem, and the saline aqueous solution is an aqueous solution of AnB, wherein the cation A is selected from one of potassium, sodium, ammonium, and hydrogen, the anion B is selected from one of hydrogen phosphate, dihydrogen phosphate, oxalate, lactate, citrate, malate, gluconate, and acetate, and n is a positive integer. The hydrated humectants in the present invention has the effect of taking part in a substitution reaction with calcium pectate inside the tobacco stems to generate a hydrated calcium salt, thereby preventing escape of water molecules, reducing evaporation and dissipation of moisture, and achieving a desirable moistening efficacy.

  • Patent number: 8534297
    Abstract: 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.
