Embodiment 1

[0017] Dissolve 10g of modified starch in 400g of water, place it in a constant temperature water bath at 60°C, then add 20g of gelatin, 20g of sucrose and 200g of maltodextrin in sequence and keep stirring. After the wall material is completely dissolved, add 50g of NaCl and 100g of NaCl 2 CO 3 , and finally use a high-speed disperser for high-speed dispersion, and finally form an emulsion with a solid content of about 50%. The slow-release alkaline microcapsules were prepared by spray-drying at an inlet air temperature of 140°C.

[0018] The slow-release alkaline microcapsules of the present invention are added to oral tobacco products to promote the gentle release of nicotine in the tobacco leaf powder in the oral cavity; especially for acidic flue-cured tobacco, the slow-release alkaline microcapsules can ensure the stability of the pH value in the product In neutral or slightly alkaline, the strength is relatively moderate, and the nicotine is released smoothly in the mo...

Embodiment 2

[0020] Dissolve 10g of modified starch in 400g of water, place it in a constant temperature water bath at 65°C, then add 20g of gelatin and 250g of maltodextrin in sequence and keep stirring. After the wall material is completely dissolved, add 220g of K 2 CO 3 , and finally use a high-speed disperser for high-speed dispersion, and finally form an emulsion with a solid content of about 55%. The slow-release alkaline microcapsules were prepared by spray-drying at an inlet air temperature of 140°C.

[0021] The slow-release alkaline microcapsules of the present invention are added to oral tobacco products to promote the gentle release of nicotine in the tobacco leaf powder in the oral cavity; especially for acidic flue-cured tobacco, the slow-release alkaline microcapsules can ensure the stability of the pH value in the product In neutral or slightly alkaline, the strength is relatively moderate, and the nicotine is released smoothly in the mouth for more than 20 minutes. It is...

Abstract

The invention discloses a slow-release alkaline microcapsule for a buccal tobacco product and a preparation method thereof. The microcapsule particularly is a microcapsule prepared by encapsulating alkali salt active ingredients with a microcapsule coating raw material; and the percentage by weight of the microcapsule coating raw material is 10 to 90 percent. The preparation method comprises the following steps of: in constant-temperature water bath with a temperature of 60 DEG C to 70 DEG C, adding the coating raw material with continuous stirring; after completely dissolving the coating raw material, adding alkali salt; and finally, carrying out high-speed dispersion on the mixture to obtain emulsion, and carrying out spray-drying on the emulsion to obtain the capsule, wherein the mass content of solid substances in the emulsion is 40 to 80 percent. The prepared microcapsule can slowly release alkalinity; the internal quality of the buccal tobacco product is promoted; and the requirement of consumers on the comfort of a smokeless tobacco product is met.

Description

technical field [0001] The invention relates to a sustained-release alkaline microcapsule for buccal tobacco products, which belongs to the field of tobacco. Background technique [0002] As the policies of countries around the world and the stricter restrictions on smoking places by anti-smoking organizations, smokeless tobacco has gradually become one of the development directions of tobacco products in the world. Our country has had many patents for smokeless tobacco products in recent years: such as CN1037317C health-care chewing tobacco, CN100593372C bag-packed snus products, CN101254025B bag-pack snus products and preparation methods, etc. [0003] According to the mode of use, smokeless tobacco products are divided into two categories: oral type and nasal type. Nicotine is a very important alkaloid in tobacco and an important component of buccal smokeless tobacco products. The release rate and amount of nicotine are important indicators of the quality and safety of ...
