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

[0021] 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:

[0022] (1) Prepare the humectant according to the weight percentage of sodium hexametaphosphate 6.25% and deionized water 93.75wt%.

[0023] (2) The humectant with the above ratio can be completely dissolved after ultrasonication for 5 minutes at room temperature and under the condition that ...

Embodiment 2

[0039] The preparation method of the humectant for improving the physical humectant performance of expanded shredded tobacco comprises preparing the humectant according to the weight percentage of potassium monohydrogen phosphate 9.375wt% and deionized water 90.625wt%. At 30°C, under the condition that the ultrasonic power is 100% of the rated power of the ultrasonic generator, potassium monohydrogen phosphate can be completely dissolved in deionized water after ultrasonication for 20 minutes.

Embodiment 3

[0041] The preparation method of the humectant for improving the physical humectant performance of expanded shredded tobacco comprises preparing the humectant according to the weight percentage of sodium dihydrogen phosphate 15wt% and deionized water 85wt%. At 35°C, under the condition that the ultrasonic power is 70% of the rated power of the ultrasonic generator, sodium dihydrogen phosphate can be completely dissolved in deionized water after ultrasonication for 15 minutes.

Abstract

A moisture-retaining agent improving physical moisture retaining performance of expanded tobacco and preparation method for the moisture-retaining agent relate to the field of tobaccos. The moisture-retaining agent is formed by the following raw material according to weight by percentages: 4% to 20% of inorganic salt and 80% to 96wt% of deionized water. The beneficial effects of the moisture-retaining agent are that moisture of the expanded tobacco loss can be delayed in low-humidity environment and prevent the expanded tobacco from excessively absorbing moisture in high-humidity environment.

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...
