preparation example Construction

[0039] Embodiments of the present invention also provide a method for preparing water-soluble dropping pills prepared by cross-linking technology, comprising the following steps:

[0040] (1) Prepare an acidic aqueous solution containing chitosan; specifically, an acidic water-soluble solution with a certain mass concentration can be prepared first, and then chitosan powder is added to the acidic water-soluble solution to make the chitosan powder swell in the acidic aqueous solution for 1~ 3h, then stirred in a constant temperature water bath at 45~65°C for 1~3h until completely dissolved, then stood still for more than 3h to defoam, and set aside. In a preferred embodiment of the present invention, use acetic acid to adjust the acidity of the aqueous solution, acetic acid is a weak acid, less corrosive, and can be added to the cigarette dripping pill formula as a safe raw material; the quality of chitosan in the acidic aqueous solution of chitosan The concentration is 0.5~1.5...

Embodiment 1

[0047] Embodiment 1 of the present invention provides a water-soluble dripping pill prepared by cross-linking technology and a preparation method thereof, and the specific preparation process is as follows:

[0048] (1) Weigh a certain amount of glacial acetic acid, and prepare an acetic acid solution with a concentration of 0.5wt% for later use;

[0049] (2) Add a certain quality of chitosan powder into the acetic acid solution in step (1) to swell for 1 hour, then stir in a constant temperature water bath at 45°C for 1 hour until completely dissolved, and prepare a chitosan acid solution with a concentration of 0.5wt%. Solution, let it stand for more than 3h to defoam;

[0050] (3) Add a certain quality of anhydrous calcium chloride powder and water-soluble essence into the chitosan solution prepared above, stir to make it fully dissolve, and make a mixed solution with a calcium chloride concentration of 1.0wt%;

[0051] (4) Take sodium alginate powder, swell it with deioni...

Embodiment 2

[0055] Embodiment 2 of the present invention provides a kind of water-soluble dropping pill prepared by cross-linking technology and preparation method thereof, and the specific preparation process is as follows:

[0056] (1) Weigh a certain amount of glacial acetic acid and prepare an acetic acid solution with a concentration of 1.5wt% for later use;

[0057] (2) Add a certain quality of chitosan powder into the acetic acid solution in step (1) to swell for 2 hours, then stir in a constant temperature water bath at 50°C for 2 hours until completely dissolved, and prepare a chitosan acid solution with a concentration of 1.0wt%. Solution, let it stand for more than 3h to defoam;

[0058] (3) Add a certain quality of anhydrous calcium chloride powder and water-soluble essence into the chitosan solution prepared above, stir to make it fully dissolve, and make a mixed solution with a calcium chloride concentration of 1.5wt%;

[0059] (4) Take sodium alginate powder, swell it with...

Abstract

The invention discloses a water-soluble dropping pill prepared by a crosslinking technology and a preparation method of the water-soluble dropping pill. The water-soluble dropping pill comprises an inner layer core liquid, a middle shell layer and an outer shell layer. The inner layer core liquid contains water and water-soluble essence, the middle shell layer is a polyelectrolyte composite gel layer formed by cross-linking reaction of sodium alginate, chitosan and calcium salt under an acidic condition, and the outer shell layer is a waterproof wax layer. The middle shell layer of the water-soluble dropping pill is the polyelectrolyte composite gel layer formed by the cross-linking reaction of the sodium alginate, the chitosan and the calcium salt under the acidic condition, and the polyelectrolyte composite gel layer has the characteristics of hardness and frangibility after being dried, so that the prepared water-soluble dropping pill is relatively good in roundness and has a certain hardness; when a consumer smokes the cigarette, the dropping pill is easily broken by pinching and has obvious blasting sound, so that the smoking requirement of the cigarette consumer can be met; the outer shell layer can prevent the middle shell layer from increasing the toughness due to water absorption, so that the weather resistance of the water-soluble dropping pill is improved, and the water-soluble dropping pill can maintain relatively stable hardness and brittleness.

Description

technical field [0001] The invention relates to the technical field of dropping pills for cigarettes, in particular, the invention relates to a water-soluble dropping pill prepared by cross-linking technology and a preparation method thereof. Background technique [0002] Adding Runxiang dripping pills to the filter rods of cigarettes has become a common method for major cigarette brands to enhance the taste of cigarettes. Traditional Runxiang dripping pills are mostly oil-soluble, that is, oil-soluble flavors and fragrances are used as the inner material of the drop pills. Oily solvents such as olive oil and capric acid glycerin are used as dilution solvents for flavors and fragrances. For example, Chinese patent CN201810269876.4 discloses a flavor containing coffee molecules, dripping pills for cigarettes and a preparation method for dripping pills for cigarettes. The coffee flavor comprises the following components in parts by mass: 5-12 parts of coffee extract; 1-5 part...
