Embodiment 1

[0019] 1) Preparation of the solution: Weigh 0.5-0.6 g of sodium alginate, add 20 ml of water, stir at 30-50°C for 1-2 hours, fully dissolve the sodium alginate, and prepare an aqueous solution of sodium alginate; weigh 1.5- 2 grams of 2% calcium chloride, dissolved in 100 ml of water;

[0020] 2) Emulsification: Add 5 ml of peppermint essence into the sodium alginate aqueous solution, and fully stir and emulsify at 1500 rpm with a magnetic stirrer for 10-15 minutes;

[0021] 3) Encapsulation: the obtained emulsion is dropped into the calcium chloride solution in the form of small droplets using a syringe, and immediately becomes calcium alginate gel beads. Stir and solidify for 1 hour;

[0022] 4) Drying: The stirred and solidified gel beads are fully rinsed with clean water and then dried at 30-50°C or naturally dried to obtain mint essence microsoft capsules. The particle size of the tiny soft capsule is between 0.5-1mm

[0023] The method of the invention does not use s...

Abstract

The invention discloses a preparation method of a small peppermint essence soft capsule taking calcium alginate as a wall material. In the preparation method, gelatin is not used as a capsule wall material for preparing a small soft capsule, peppermint essence is added in 3% sodium alginate aqueous solution, a magnetic stirrer is used for fully mixing and emulsifying, and emulsion is dripped in 2% calcium chloride solution, mixed and cured for 1 hour, and naturally dried. The particle size of the small soft capsule is 0.5-1mm, special equipment and an emulsifier are not used in preparation, only the common magnetic stirrer is used, the types of medicaments used by the capsule wall material are few, the method is simple, convenient and feasible, the price is low, the particle size can be adjusted by using syringes of different types, and the preparation method is good in controllability and easy to operate.

Description

technical field [0001] The invention belongs to a method for preparing tiny soft capsules, in particular to a method for preparing mint essence micro soft capsules with calcium alginate as the wall material. Background technique [0002] Essence or essential oil is a volatile liquid (or oily substance), which is expensive and has a small dosage, and a small amount of it will have a good effect. However, it is difficult to store because it is easy to volatilize, and it is also inconvenient to carry. However, the existing soft capsules are too large and inconvenient to use, and are not suitable for wrapping essence. Therefore, the miniature essence (essential oil) soft capsule that is easy to use and can be evenly distributed in the material has huge demand and application prospects at home and abroad in the application of cosmetics and food industries. [0003] Gelatin is the most basic capsule material of soft capsules, but if the wrapper is rich in aldehydes and ketones, ...
