Description

Technical Field

[0001] The invention relates to the technical field of medicine and health care, and in particular to an aloe capsule and a preparation method thereof. Background Art

[0002] As a natural plant, aloe vera has been widely used in food, medicine, cosmetics and other fields since ancient times. Its rich nutrients and various bioactive substances give it a wide range of health benefits, such as anti-inflammatory, anti-oxidation, moisturizing and promoting intestinal health. With the improvement of health awareness, the market demand for health products containing aloe vera ingredients is growing, especially aloe vera capsules as a convenient oral supplement, which are favored by consumers.

[0003] However, the aloe vera capsules currently on the market often have problems in the preparation process, such as insufficient processing of raw materials, low efficiency of active ingredient extraction, single product formula and backward preparation process. Specifically, some aloe vera capsules lack effective purification methods in raw material processing, resulting in a large number of impurities and ineffective ingredients in aloe vera, affecting the purity and safety of the product; at the same time, for the extraction of key active ingredients such as aloe polysaccharides, the extraction efficiency of existing technologies is low, and it is difficult to ensure the purity of polysaccharides. Traditional extraction methods may use a large amount of chemical reagents, causing environmental pollution, and may also affect the structure and biological activity of polysaccharides, limiting their application in high-end products.

[0004] In addition, the existing aloe vera capsule formula often ignores the synergistic effect of multiple nutrients. The addition of aloe vera extract alone cannot meet consumers' demand for comprehensive health. In terms of preparation technology, traditional mixing, granulation and filling methods are also prone to uneven distribution of ingredients, different particle sizes, loose filling and other problems, affecting the quality and stability of the product. Summary of the invention

[0005] In view of this, the present invention provides an aloe capsule and a preparation method thereof to solve the above problems.

[0006] The technical solution of the present invention is achieved as follows: an aloe capsule comprises the following raw materials in parts by weight: 30-40 parts of purified aloe gel powder, 30-50 parts of aloe polysaccharide extract, 5-10 parts of compound prebiotics, 2-5 parts of antioxidant plant extract, 10-20 parts of vitamin E, 10-15 parts of dietary fiber, 5-15 parts of glycerol, and 10-30 parts of natural capsule shell material.

[0007] Furthermore, an aloe capsule comprises the following raw materials in parts by weight: 35 parts of purified aloe gel powder, 40 parts of aloe polysaccharide extract, 8 parts of compound prebiotics, 4 parts of antioxidant plant extract, 15 parts of vitamin E, 13 parts of dietary fiber, 10 parts of glycerin, and 20 parts of natural capsule shell material.

[0008] Furthermore, the method for purifying aloe vera gel powder comprises the following steps:

[0009] (1) Raw material pretreatment: picking aloe leaves, removing mud and sand and washing with clean water, peeling off the outer skin to obtain aloe pulp, and squeezing the juice to obtain juice;

[0010] (2) Ultrafiltration: The juice was ultrafiltered using an ultrafiltration membrane with a pore size of 50-100 nm. Ultrasonic treatment was introduced during the ultrafiltration process for 4-6 h with an ultrasonic power of 200-400 W and a frequency of 30-60 kHz.

[0011] (3) Filtration and concentration: The ultrafiltered aloe vera gel is passed through a 100-300 mesh sieve to remove residual tiny impurities and fibers, and concentrated to 1 / 4-1 / 3;

[0012] (4) Freeze drying: The concentrated aloe vera gel is placed in a freezer and quickly frozen to -50 to -30°C and maintained for 6 to 10 hours to obtain purified aloe vera gel powder.

[0013] Furthermore, the aloe polysaccharide extract comprises the following preparation method:

[0014] (1) Raw material pretreatment: picking aloe leaves, cleaning and peeling, cutting aloe flesh into pieces, and stirring to form a paste;

[0015] (2) Enzymatic hydrolysis: the homogenized aloe paste is mixed with a composite enzyme, wherein the composite enzyme is pectinase, cellulase and acid protease in a mass ratio of (2.5-5.5):(1.2-2.4):(6.3-10.2), the enzyme dosage is 1-4% of the mass of the aloe paste, the enzymatic hydrolysis temperature is adjusted to 40-60° C., the pH is 6-8, and the enzymatic hydrolysis time is 3-8 h to obtain an aloe enzymatic hydrolyzate;

[0016] (3) Membrane separation and extraction: After the enzymatic hydrolysis is completed, the aloe hydrolysate is filtered or centrifuged to separate the supernatant so that the molecular weight of the hydrolysate is ≤1000Da, thereby obtaining the aloe polysaccharide extract.

[0017] Furthermore, the composite prebiotics are oligofructose and inulin in a mass ratio of 1-5:6-8.

[0018] Furthermore, the antioxidant plant extracts are green tea extract, grape seed extract and partridge tea extract in a mass ratio of (12-32):(8-10):(2-9).

[0019] Furthermore, the dietary fiber is selected from oat fiber and apple fiber in a mass ratio of 5-8:10.

[0020] Furthermore, the natural capsule shell material is alginate and plant cellulose in a mass ratio of 6.5-9.5:3.5-6.5.

[0021] Furthermore, a method for preparing aloe capsules comprises the following steps:

[0022] S1, stirring the purified aloe gel powder, aloe polysaccharide extract, compound prebiotics, antioxidant plant extract, vitamin E, dietary fiber and glycerin for air flow mixing for 10-30 minutes to obtain a core material mixture,

[0023] S2, adding the above mixture into a granulator for granulation, drying, and granulation to obtain a particle size of 20-100 μm;

[0024] S3, filling the above particles into natural capsule shell materials to obtain aloe capsules.

[0025] Furthermore, the gas mixed in the airflow is nitrogen or carbon dioxide, the airflow velocity is 5-20 m / s, and the airflow pressure is 1000-5000 Pa.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention combines a variety of high-value ingredients such as purified aloe gel powder, aloe polysaccharide extract, compound prebiotics, antioxidant plant extracts, vitamin E, dietary fiber, etc. through a carefully designed raw material ratio, which not only enriches the nutritional components of the product, but also achieves the synergistic effect of multiple health functions, such as enhancing immunity, promoting intestinal health, anti-oxidation and moisturizing, etc., fully satisfying modern people's pursuit of healthy life.

[0028] (1) Improving product quality and efficacy: In the preparation method of purified aloe vera gel powder, ultrafiltration combined with ultrasonic treatment can effectively remove impurities and improve the purity of aloe vera gel powder. The introduction of ultrasonic waves can accelerate the ultrafiltration process and destroy the cell structure, so that more effective ingredients can be released. After filtration, concentration and freeze-drying, the quality of the gel powder is further guaranteed and the active ingredients of aloe vera are retained. Enzymatic hydrolysis and membrane separation are used to extract aloe vera polysaccharide extracts, which improves the extraction efficiency and purity of polysaccharides. The pectinase, cellulase and acid protease in the complex enzyme work synergistically to more thoroughly decompose the aloe vera tissue and release polysaccharides. Membrane separation technology can accurately control the molecular weight of polysaccharides, remove impurities, and obtain high-purity polysaccharide extracts. The addition of compound prebiotics, antioxidant plant extracts, vitamin E and dietary fiber enriches the nutritional components of aloe vera capsules and has a synergistic effect. Complex prebiotics can regulate intestinal flora and promote intestinal health; antioxidant plant extracts have antioxidant and anti-aging effects; vitamin E is a powerful antioxidant that helps protect cells from damage by free radicals; dietary fiber can promote intestinal motility and prevent constipation.

[0029] (2) Optimization of preparation process: The use of nitrogen or carbon dioxide as gas in air flow mixing avoids the oxidation of oxygen on the product and ensures the stability of the product. The control of air flow velocity and pressure can fully mix the raw materials and improve the uniformity and efficiency of mixing. The granulation, drying and granulation process obtains particles with a particle size of 20-100 μm, which is easy to fill into the natural capsule shell material, ensuring the quality and stability of the product. The natural capsule shell material is composed of alginate and plant cellulose, has good biocompatibility and stability, and has no toxic side effects on the human body.

[0030] In summary, the aloe vera capsule formula and its preparation method show significant beneficial effects in terms of nutritional components, extraction efficiency, product purity and preparation process, providing the market with a high-quality and high-efficiency aloe vera health product that meets the health needs of consumers.

[0098] Test Example 1 - Active ingredient test

[0099] The aloe gels prepared in the above Examples 1-3 and Comparative Examples 1-6 were tested for the active ingredient contents of emodin, aloin, rhein, aloesin, aloe uruxin, aloe tincture, and aloe arbutin using high performance liquid chromatography. The test results are as follows:

[0100]

[0101]
