Problems solved by technology

A large number of hydrophilic substrates such as polysaccharides, pectin and inorganic ions in tobacco provide a good material basis for water absorption. The oil and wax between the cutin of tobacco leaves provide a barrier to prevent water loss. The porous structure of tobacco also provides a barrier for water absorption. Moisture absorption provides a larger space, but this structure is also faster for tobacco to lose moisture in a low-humidity environment

Embodiment 1

[0023] In a constant temperature and humidity chamber, set the temperature at (22±1)°C, respectively in a low-humidity environment with a relative humidity of (40±2)% and a high-humidity environment with a relative humidity of (75±2)%, through the oven method ( YC / T31-1996 "Preparation of Tobacco and Tobacco Products Samples and Determination of Moisture Oven Method") to calculate the initial moisture content of expanded cut tobacco, and use the difference method to calculate the instant moisture content of expanded cut tobacco. ratio of deionized water) to compare the instant moisture content, and evaluate the moisturizing effect of each moisturizer. The specific process is as follows:

[0024] (1) Prepare the moisturizer according to the weight percentage of 3.125wt% lactic acid, 3.125wt% sodium lactate and 93.75wt% deionized water.

[0025] (2) Fully dissolve lactic acid and sodium lactate in deionized water.

[0026] (3) Weigh 3.20 g of the humectant obtained in step 2, a...

Embodiment 2

[0041] The humectant used to improve the physical moisturizing performance of expanded shredded tobacco is prepared according to the weight percentage of 3.5wt% malic acid, 7wt% ammonium malate and 89.5wt% deionized water, and make malic acid and ammonium malate fully Dissolved in deionized water that is.

Embodiment 3

[0043] The humectant used to improve the physical moisturizing performance of expanded shredded tobacco is prepared according to the weight percentage of 2wt% acetic acid, 6wt% sodium acetate and 92wt% deionized water, and fully dissolve malic acid and ammonium malate in deionized Get it in water.

Abstract

The invention provides a humectant capable of improving the physical moisture retention performance of expanded cut tobacco and a preparing method thereof and relates to the field of tobacco. The humectant comprises, by weight, 1-10wt% of organic acid, 1-10wt% of organic acid salt and 80-98wt% of deionized water. The humectant can slow dissipation of moisture of expanded cut tobacco in low-humidity environments and prevent expanded cut tobacco from absorbing moisture excessively in high-humidity environments.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a humectant for improving the physical moisture retention performance of expanded shredded tobacco and a preparation method thereof. technical background [0002] Expanded shredded tobacco is shredded tobacco that has been processed by expansion technology. It has been used in the tobacco industry for more than 40 years, and the most widely used one is the expanded shredded tobacco produced by dry ice (carbon dioxide) expansion technology. Dry ice expansion technology uses carbon dioxide to impregnate tobacco leaf cells under certain pressure conditions, and then allows the impregnated shredded tobacco to expand rapidly in high-temperature airflow, and then cools the shredded tobacco to restore its moisture content to a level that can meet the processing requirements . The raw material of the expanded shredded tobacco can be flue-cured tobacco or Burley tobacco, and oriental tobacco can a...
