Example Embodiment

[0029] Example 1,

[0030] Refer to figure 1 , The method for preparing a tea plant soft capsule in the embodiment of the present invention includes the following main steps in sequence:

[0031] a) Preparation of tea extract: the picked tea leaves are washed, dried, crushed, and passed through a 40-mesh sieve to obtain tea powder. The tea powder is 1:40 (w / v, g / ml) and 0.06mol / L sodium hydroxide The solution is evenly mixed, that is, 40 ml of 0.06mol / L sodium hydroxide solution is added to each 1 gram of tea powder; the extract is leached in a water bath at 90-100°C for 60 min, and the extract is shaken every 5 min; Adjust the pH to 5.8 with hydrochloric acid to obtain a tea extract.

[0032] b) Modified tea fiber preparation: take 5g of tea residues washed to neutrality and dried by hot air in a three-necked flask with a stirring device, add 50ml of 75% ethanol, 50ml of 20% NaOH solution, and alkalization temperature of 30℃. The alkalization reaction was carried out at 200r / min ...

Example Embodiment

[0035] Example 2,

[0036] In the embodiment of the present invention, the enzymatic hydrolysis treatment process is adopted for the tea dregs after the tea leaves are leached, and the rest of the preparation method is basically the same as in embodiment 1, the difference is:

[0037] a) Enzymatic hydrolysis of tea dregs: Mix 20% NaOH (or 2% dilute sulfuric acid solution) solution with the tea dregs after washing to neutrality and drying 10:1, (10mL of liquid corresponds to 1g of solid) in a water bath at 120℃. After boiling for 30 minutes, filter and wash until neutral. Add 2g of tea dregs fiber and 100U of cellulase washed to neutrality into a 250ml flask with stopper, then add 100ml of 0.2mol / L HAc-NaAc buffer with a pH of 4.8, and place it under constant temperature shaking In the vessel, react at 50°C for 24 to 48 hours. After the enzymatic hydrolysis is completed, the tea dregs are filtered out, the enzymatic hydrolysate is incorporated into the tea extract, and the next st...

Example Embodiment

[0039] Example 3.

[0040] Preparation of the soft capsule described in the embodiment of the present invention has different enzymatic hydrolysis methods for the tea residue fiber, and other preparation processes are basically the same as in Example 2. In this embodiment, the cellulase of the enzymatically hydrolyzed tea dregs is adjusted to one or more of a multi-enzyme system such as polygalacturonase, β-glucosidase, pectinase, and protease to act synergistically.

Abstract

The invention is applicable to the technical field of soft capsules, and discloses a tea leaf-sourced plant soft capsule shell. The tea leaf-sourced plant soft capsule shell is prepared mainly from 50-75wt% of a tea leaf extract, 0-10wt% of modified tea fiber, 3-15wt% of carboxymethylcellulose (CMC), 0-5wt% of hydroxypropylmethyl cellulose (HPMC), 1-10wt% of carrageenan, 0.01-5wt% of gellan gum and 10-30wt% of a plasticizer, is applicable to medicines, food, health products, daily chemical products, chemical products and other capsule products, and has no special application restriction. The invention further provides a preparation method of a tea leaf-sourced plant soft capsule. The preparation method comprises the following steps: preparing the tea leaf extract, preparing the modified tea fiber, preparing a gum solution and preparing a soft capsule to obtain the tea leaf-sourced plant soft capsule. The soft capsule shell contains a variety of active substances contained in tea leaves, and thus has pharmacological activity and a health-care efficacy; various physical and chemical indexes meet requirements of relevant standards; the soft capsule shell can also be processed by using the conventional gelatin capsule processing equipment, so that the equipment utilization rate is improved; raw materials are low in cost; and industrial production is easy to implement.

Description

【Technical field】 [0001] The invention relates to the technical field of capsules, and relates to a preparation method of plant-based soft capsules, in particular to a high-health plant-based soft capsule shell with tea as the basic raw material and its application, and a preparation method of tea-plant soft capsules. 【Background technique】 [0002] Capsule is one of the most basic dosage forms of modern medicine and functional food, and its development and application prospects are very broad. Compared with other dosage forms, soft capsules have many advantages such as beautiful appearance, precise loading, high bioavailability, strong drug stability, and can shield the bad smell of the contents at the same time. Studies have found that the quality of soft capsules is closely related to the selection and compatibility of capsule shell materials. At present, the vast majority of soft capsules are processed from gelatin as the main raw material. Reality shows that the use o...
