[0021] The invention provides a selenium-enriched camellia oil capsule capable of effectively improving health-care effects and a preparation method thereof.
[0022] In one embodiment of the present invention, the selenium-rich camellia oil capsules that can effectively improve the health care effect contain unsaturated fatty acids, saturated fatty acids, tea polyphenols, camellia saponins, squalene, 14-methylpentadecanoic acid, linoleic acid, stearic acid, linolenic acid, protein, cellulose, vitamin E, thiamine, riboflavin, niacin, magnesium, calcium, iron, zinc, copper, manganese, potassium, phosphorus and selenium.

[0026] Specifically, the unsaturated fatty acid contains 68%-87% of monounsaturated fatty acids and 2%-14% of polyunsaturated fatty acids in terms of mass percentage per 100 grams.
[0027] On the other hand, Figure 1 As shown, the present invention also proposes a method for preparing selenium-enriched camellia oil capsules that can effectively improve health care effects, and the preparation method comprises the following steps: Step 1: Pre-treatment of raw materials: Select high-quality camellia seeds and selenium-rich millet, wash and drain; Step 2, taking tea seeds and crushing selenium-enriched millet: After the camellia seeds are shelled, they are subjected to microwave drying treatments under different conditions twice to obtain dried tea seed kernels, and the selenium-enriched millet in step 1 is crushed into powder; Step 3, preparation of crude tea oil: mixing the crushed selenium-rich millet with the tea seed kernels dried in step 2 and adding them into a cold press, and filtering after cold pressing to obtain crude tea oil rich in selenium; Step 4, supercritical carbon dioxide refining: the crude camellia oil in step 3 is sent to a supercritical extraction device, carbon dioxide or nitrogen with a certain pressure is added, and two extractions are performed under supercritical carbon dioxide or nitrogen fluid reaction conditions, and carbon dioxide or nitrogen is discharged to remove impurities, thereby obtaining high-quality selenium-rich camellia oil; Step 5. Preparation of selenium-rich camellia oil capsules: Mix the selenium-rich camellia oil in step 4 with an appropriate amount of auxiliary materials to form a capsule core liquid, mix the capsule core liquid and capsule material gelatin in a certain proportion, and then add them to a soft capsule machine to make selenium-rich camellia oil capsules through the soft capsule machine.
[0028] Specifically, in the step 2, the specific conditions of the microwave drying treatment under two different conditions are: the frequency of the first microwave drying is 800-1000 MHz, and the drying time is 2-4 minutes; the frequency of the second microwave drying is also 800-1000 MHz, and the drying time is 1-2 minutes. The interval between the two microwave dryings is 5-20 minutes, and the moisture content of the tea seeds after drying is 5-8%.
[0029] Specifically, in the step 4, the specific conditions for performing two extractions are: the pressure of the first extraction is 8-10MPa, the temperature is 32-36°C, and the time is 30-50 minutes. Through this extraction, odor components (such as low-level aldehydes, etc.), some free fatty acids and other impurities can be removed.
[0030] The second extraction is performed at a pressure of 12-13 MPa, a temperature of 38-45°C, and a time of 15-30 minutes. This extraction can remove impurities such as peroxides and remaining free fatty acids.
[0031] Specifically, in the step 5, the auxiliary material is one of selenium-enriched malt, ganoderma lucidum extract, dendrobium extract or grape seed oil.
[0032] Specifically, the principle of the supercritical carbon dioxide or nitrogen extraction of the present invention is based on the characteristics of supercritical fluids, and utilizes the influence of pressure and temperature on the solubility of supercritical fluids to achieve effective extraction and separation of target components. Supercritical fluids refer to fluids whose temperature and pressure exceed the critical temperature and critical pressure of the substance. In this state, supercritical CO2 has a density similar to that of a liquid and a diffusion property similar to that of a gas.
[0033] The principle of the supercritical carbon dioxide extraction and separation process is to utilize the special dissolving effect of supercritical carbon dioxide on certain special natural products, and to utilize the relationship between the solubility of supercritical carbon dioxide and its density, that is, to utilize the influence of pressure and temperature on the solubility of supercritical carbon dioxide.
[0034] In the supercritical state, supercritical carbon dioxide is brought into contact with the substance to be separated, so that it can selectively extract components of different polarity, boiling point and molecular weight in sequence. Of course, the extract obtained corresponding to each pressure range cannot be single, but the conditions can be controlled to obtain the best proportion of mixed components, and then the supercritical fluid is turned into ordinary gas by means of decompression and heating, and the extracted substance is completely or basically precipitated, thereby achieving the purpose of separation and purification. Therefore, the supercritical fluid carbon dioxide extraction process is a combination of extraction and separation.
[0035] Characteristics of supercritical CO2: 1. Solubility: In the supercritical state, the solubility of CO2 is closely related to its density, and its solubility can be controlled by adjusting the pressure and temperature. Generally, an increase in pressure will increase the solubility of CO2, while a decrease in temperature will also increase its solubility; 2. Selectivity: Supercritical CO2 is selective for components of different polarity, boiling point and molecular weight, and can extract these components in sequence; 3. Environmental protection: CO2 is non-toxic, odorless, does not pollute the environment, and is easy to separate from the product without leaving any residue.
[0036] Specifically, the supercritical CO2 extraction method of the present invention can efficiently extract high-quality camellia oil from tea seeds, and the yield of supercritical CO2 extraction is significantly higher than that of traditional steam distillation, while reducing the loss of active ingredients, increasing the oil yield, and maintaining the nutritional components of camellia oil. In addition, this method also has environmental advantages, because supercritical CO2 can be recycled, reducing the impact on the environment.
[0037] The quality of camellia oil is effectively improved by combining supercritical fluid extraction and molecular distillation (SFE-MD), ensuring that the acid value is reduced and the active ingredients are retained.
[0038] Specifically, the present invention has the following advantages: 1. The quality and selenium content of camellia oil are improved by using supercritical fluid technology.
[0039] 2. The capsule form is easy for the human body to absorb and improves the bioavailability of the active ingredients.
[0040] 3. The unsaponifiable matter in camellia oil is retained, which enhances the health-care effect.
[0041] 4. The selenium-enriched camellia oil capsule can stay in the human intestine for a long time, improve the absorption rate of the active ingredients, and retain the unsaponifiable substances of camellia oil, such as γ-tocopherol, β-sitosterol and squalene.
[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
