Abstract：This study aims to investigate the hygroscopic characteristics of 8 tobacco granules for heated tobacco products(TGHTP) made by different flue-cured tobacco materials. Dynamic water adsorption(DVS) and low-field nuclear magnetic resonance(LF-NMR) were used to determine the moisture sorption behavior and water states of TGHTP. The differences of hygroscopic characteristics in different samples were obtained via principal component analysis. Moisture sorption isotherms of TGHTP presented a typical “J” shape. The DLP and GAB models showed better fitting effects, with mean R2 values of 0.9996 and 0.9961, respectively. Monolayer moisture contents of TGHTP ranged from 13.00 to 14.53 g/100g. During the moisture sorption process(0～14d), moisture contents of 8 TGHTP was significant increased, which was positively correlated with bound water content(r = 0.641, P < 0.01). The increase in bound water peak area of TGHTP after moisture absorption for 1 d and 14 d were 417-655 and 2384-3221, respectively. The hygroscopic properties of TGHTP were significantly influenced by the stalk positions and the region of the flue-cured tobacco materials. The moisture adsorption amount(14 days)of middle tobacco granules from the same origin was significantly higher than that of upper and lower tobacco granules. In terms of TGHTPs from upper stalk positions, moisture absorption amount of TGHTP from Sanmenxia, Henan at 14 d was significant higher than those from Zunyi, Guizhou and Kunming, Yunan. As for TGHTPs from lower stalk positions, moisture absorption amount of TGHTP from Kunming, Yunan at 14 d were significant higher than those from Zunyi, Guizhou.
