Embodiment 1
[0020] (1) Sansi pretreatment: place the three cigarettes respectively in a constant temperature and humidity chamber at a temperature of (22±1)°C and a relative humidity of (60±2)% for 48 hours to be used for standby;
[0021] (2) The three wires are measured separately: each sample is taken out of the constant temperature and humidity chamber after being balanced for 48 hours, sealed and placed in the test environment to balance for a period of time, and then the initial water activity of each sample is detected with a water activity meter wi始 and initial temperature T 始 , and the termination water activity a after a predetermined period of time wi终 and termination temperature T 终 . Before starting the measurement, ensure that the sample is in a sealed state, and place it in the same environment as the sensor for 30 minutes to achieve complete equilibrium, so as to avoid humidity transfer between the sample and the environment before and after the test. Put the substance ...

[0029] (1) Sansi pretreatment: place the three cigarettes respectively in a constant temperature and humidity chamber at a temperature of (22±1)°C and a relative humidity of (60±2)% for 48 hours to be used for standby;
[0030] (2) The three wires are measured separately: each sample is taken out of the constant temperature and humidity chamber after being balanced for 48 hours, sealed and placed in the test environment to balance for a period of time, and then the initial water activity of each sample is detected with a water activity meter wi始 and initial temperature T 始 , and the termination water activity a after a predetermined period of time wi终 and termination temperature T 终 . Before starting the measurement, ensure that the sample is in a sealed state, and place it in the same environment as the sensor for 30 minutes to achieve complete equilibrium, so as to avoid humidity transfer between the sample and the environment before and after the test. Put the substance ...
Embodiment 3
[0038] (1) Pre-treatment of shredded tobacco: put the shredded tobacco in a constant temperature and humidity chamber with a temperature of (22±1)°C and a relative humidity of (60±2)% to balance for 48 hours for later use;
[0039] (2) Spray humectant: take out the shredded tobacco after equilibrating for 48h, weigh four portions, 10g each, and spray the control (deionized water), propylene glycol, and self-developed humectant at a ratio of 0.5% with a throat sprayer 1#, after mixing evenly, open it and place it in a constant temperature and humidity box for testing.
[0040] (3) Each sample is sealed and placed in the test environment to balance for a period of time, and then the initial water activity of each sample is detected with a water activity meter a wi始 and initial temperature T 始 , and the termination water activity a after a predetermined period of time wi终 And the termination temperature T end. Before starting the measurement, ensure that the sample is in a sea...
