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...

Abstract

The invention discloses an evaluation method for moisturizing properties of cigarettes. The cigarettes comprise a variety of composing components of cut tobacco, bulging filaments, stem filaments and the like. The method comprises the following steps: (1) placing each composition component in a constant temperature-humidity box separately to be balanced for at least 48h for later use; (2) measuring the initial water activity awi beginning and the initial temperature T beginning of each composing component in a sealed state and the final water activity awi end and the final temperature T end after a predetermined period of time; (3) calculating the physical moisturizing evaluation index M according to a formula, wherein when M is less than 0, preparing various raw materials into the cigarettes in a mixed manner proportionally, and then spontaneously losing water, and when the value is more negative, the water loss is faster; when M is greater than 0, after preparing various raw materials into the cigarettes in the mixed manner proportionally, spontaneously absorbing water, and when the value is greater, water is absorbed faster or the water loss is slower. The evaluation method for the moisturizing properties of the cigarettes disclosed by the invention can solve the problems of tedious test process, long period, serious influence of environmental factors and the like in the existing evaluation method.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to an evaluation technology and application of tobacco physical moisture retention based on a thermodynamic method. Background technique [0002] Tobacco physical moisture retention refers to the water retention and water retention capacity of tobacco, and is one of the important factors affecting the sensory quality and storage quality of tobacco. The physical moisture retention performance of tobacco is affected by conditions such as tobacco raw materials (cut tobacco, expanded shreds, and cut stems, collectively referred to as "three shreds" below, which are the main raw materials in cigarettes), sugar and spice formula, processing technology, and packaging materials. The rate of moisture loss from a cigarette. In recent years, most of the research on moisturizing at home and abroad has focused on the research on moisturizing agent, auxiliary material moisturizing technology, moisturizing...
