Problems solved by technology

[0005] In some special fields, for example, the soft capsules embedded in the filter rods for flavoring and humidification are fragile soft capsules with certain strength and brittleness. The release of substances changes the taste and experience, and has the functions of moisturizing, increasing flavor, reducing coke and reducing harm. It requires that the capsule

Embodiment 1

[0022] The steps of this embodiment are as follows:

[0023] ① Use gelatin as the main wall material, add glycerin, spices, and sunscreen to make a glue, add 0.3% of the weight of calcium chloride to the glue, and use the soft capsule pressing process to make soft capsules with a loading capacity of 500 mg and carry out drying process;

[0024] ② Prepare a chitosan solution with a concentration of 0.5% with a concentration of 0.2% acetic acid solution, put the prepared soft capsules into the chitosan solution, and stir at room temperature for 15 minutes at a stirring speed such that the soft capsules form in the solution well. flow is appropriate;

[0025] ③ Put the soft capsules treated in step ② into ethanol for 3 minutes to dehydrate;

[0026] ④ Place the soft capsules processed in step ③ in a tumbler with a humidity of 35%RH for 5 hours;

[0027] ⑤ The soft capsules processed in step ④ were left to dry for 36 hours in a space with a humidity of 35%RH to obtain soft...

Embodiment 2

[0031] The steps of this embodiment are as follows:

[0032] ① Use gelatin, gellan gum, and dextrin as the main wall material raw materials, add glycerin, spices, and opacifiers to make a glue, add calcium chloride accounting for 0.2% of the weight of the glue, and use the co-extrusion method for soft capsule drop pills Machine-made round soft capsules with a diameter of 3.6mm and dried;

[0033] ② Prepare a chitosan solution with a concentration of 0.5% with water-soluble chitosan, put the soft capsules prepared in step ① into the chitosan solution, stir at room temperature for 3 minutes, and the stirring speed is such that the soft capsules form a good flow in the solution. appropriate;

[0034] ③ Put the soft capsules treated in step ② into ethanol for dehydration for 2 minutes;

[0035] ④ Put the soft capsules processed in step ③ into a tumbler with a humidity of 35%RH for 3 hours;

[0036] ⑤ The soft capsules processed in step ④ were left to dry for 36 hours in a space...

Embodiment 3

[0040] The steps of this embodiment are as follows:

[0041] ① Use alginate and dextrin as the main wall material raw materials, add glycerin, spices, and opacifiers to make glue, add calcium chloride accounting for 3% of the weight of the glue, and use the emulsion film-forming method to make a diameter of 3.6mm round soft capsules and dry them;

[0042] ② Prepare a chitosan solution with a concentration of 0.8% from water-soluble chitosan. Wash the soft capsules prepared in step ① with distilled water and put them into the chitosan solution. Stir at room temperature for 2 min. The stirring speed is the same as the soft capsule in the solution. It is advisable to form a good flow;

[0043] ③ Put the soft capsule treated in step ② into ethanol for dehydration for 1 min;

[0044] ④ Put the soft capsules processed in step ③ into a tumbler with a humidity of 40%RH for 3 hours;

[0045] ⑤ The soft capsules processed in step ④ were left to dry for 36 hours in a space with a humi...

Abstract

The invention provides a moistureproof treatment method for soft capsules. By the method, the problems that soft capsules for filter sticks are in contact with air, continuously absorb moisture from the air and are softened, adhered and the like because of being affected with damp, so that the quality, appearance and application of the soft capsules are influenced are solved, and the requirements that the soft capsules which are embedded in the filter sticks and are used for enhancing aroma and humidifying can be moistureproof and are easy to break are met. According to the method, polyvalent metal salts are added into soft capsule wall materials and are reacted with chitosan, so that water-insoluble chitosan metal salt chelates can be formed through the reaction between the metal salts and the chitosan and are coated on the outer surfaces of the soft capsules, the waterproof performance of the soft capsules is greatly improved, the water resistance and moisture resistance of the soft capsule wall materials are improved, the brittle characteristics of the soft capsules are kept, the retention time of the filter sticks is prolonged, and the influence of an external environment on the quality, appearance and application of the soft capsules is reduced.

Description

technical field [0001] The invention relates to the flavoring of cigarettes, in particular to the field of aftertreatment of soft capsule walls for cigarette filter rods. Background technique [0002] Capsules are usually divided into two categories: hard capsules and soft capsules according to the difference in their shells: hard capsules are made of a certain amount of medicine (or medicinal material extract) and appropriate auxiliary materials (or no auxiliary materials) into uniform powder or Granules are made by filling hollow hard capsules; soft capsules are made by dissolving a certain amount of drugs (or medicinal material extracts) in appropriate excipients, and then sealing them in spherical or Among olive-shaped soft capsules, generally soft capsules are required to have a certain degree of flexibility and resistance to mechanical pressure, and the strength of the wall material is relatively high. Soft capsules usually use gelatin, alginate, dextrin, etc. as the ...
