Embodiment 1

[0035] A preparation method of a high-efficiency anti-leakage water-carrying capsule, which is produced according to the following steps: preparing a core layer, the core layer is a calcium chloride aqueous solution with a concentration of 10%; preparing a capsule wall layer, and the raw material of the capsule wall layer is sodium alginate solution , the concentration is 3%; the first water blocking layer is prepared, and the first water blocking layer is cyanoacrylate. The operation steps are as follows: (1) preparing capsules by back-dropping method, the core layer is calcium chloride aqueous solution, and the raw material of capsule wall layer is sodium alginate solution; (2) the capsules obtained in step (1) are dispersed in dimethyl carbonate, The cyanoacrylate was added dropwise to the dispersion system until the first water-blocking layer was formed on the surface of the capsule. In order to ensure the fluidity of the sodium alginate when preparing the capsules, the te...

Embodiment 2

[0037] A preparation method of a high-efficiency anti-leakage water-carrying capsule, which is produced according to the following steps: prepare a core layer, the core layer is a mixed solution of water, essence and calcium chloride, the concentration of essence is 20%, and the concentration of calcium chloride solution is 10%; prepare the wall layer, the raw material of the wall layer is sodium alginate solution, the concentration is 3%; prepare the first water blocking layer, the first water blocking layer is cyanoacrylate; prepare the second water blocking layer, the second The water blocking layer is a mixed solution of photocurable resin monomer and initiator. The operation steps are as follows: (1) Capsules are prepared by the reverse drop method, the core layer is a mixed solution of water, essence and calcium chloride, and the raw material of the capsule wall layer is sodium alginate solution; (2) The surface of the capsule is coated with the first water-blocking layer...

Abstract

The invention relates to an efficient leakage-proof water-loaded capsule and a preparation method thereof. The capsule is of a structure with at least three layers and sequentially comprises a core layer, a capsule wall layer and a water blocking layer from inside to outside, the water blocking layer wraps the capsule wall layer and is made of polyalkylcyanoacrylate, the seven-day permeable rate of the efficient leakage-proof water-loaded capsule is smaller than 4%, and spherical degree SF is smaller than 0.07. The capsule prepared by the method is high in forming rate, uniform in particle diameter, remarkable in water-blocking and leakage-proof effect, long in storage life, simple and convenient in manufacturing process, the shape of the capsule is smooth, mellow and full, and the capsule can be directly used for processing of foods, medicines and cigarette products.

Description

technical field [0001] The invention belongs to the field of capsule preparation, in particular to a high-efficiency anti-leakage water-carrying capsule. Background technique [0002] Encapsulation technology is used to wrap and seal water or water-soluble active ingredients to form capsules, so as to keep the water in the capsules free of leakage during long-term storage during transportation and shelf life. It has always been a research hotspot and difficulty in the fields of food, medicine, and tobacco. [0003] The choice of capsule wall material determines the mechanical properties and permeability of the capsule. Calcium alginate is the most commonly used wall material in food and medicinal capsules. Calcium alginate capsules prepared by the dropping method using calcium ion solution as a coagulation bath have been put into industrial production and commercialized. [0004] In the prior art, there are many reports on calcium alginate capsules coated with oil or oil-so...
