The lipid-lowering effect was good, and the ratio of food intake to excretion of mice was 1.5. The digestive ability was strong, and there was no indigestion or diarrhea. There were no obvious side effects. The mice had moderate weight, shiny hair, and normal activity.

[0042] Embodiment 2: This embodiment provides a Chinese medicine rice bran edible medicinal composition, comprising: 65 parts of rice bran superfine powder, 25 parts of Poria superfine powder, and 15 parts of freeze-dried hawthorn pieces.

[0043] A method for preparing a Chinese medicinal rice bran edible composition comprising:

[0044] S1, select high-quality rice husk, after crushing and stabilization treatment, use a mixed enzyme solution of lipase and cutinase to mix with rice bran, and carry out constant temperature oscillation reaction, after the reaction ends, rinse the rice bran with deionized water for many times until the eluate is clarified, and then the rice bran after dewaxing is low-temperature dried to remove excess moisture;

[0047] S4, mixing the rice bran superfine powder and Poria cocos superfine powder after enzymolysis treatment with freeze-dried hawthorn pieces to obtain a final product;

[0048] S5. After removing excess moisture from the final product by low-temperature drying, the final product is sealed and packaged using vacuum packaging technology.

[0049] Specifically, in step S1, the mixed enzyme solution includes 0.5% to 1% lipase and 0.3% to 0.5% cutinase, the pH value is 6.5 to 7.5, the mixing ratio of rice bran to the mixed enzyme solution is 1:5 to 8 g / mL, the constant temperature oscillation reaction temperature is 45 to 55° C., and the reaction time is 3 to 4 hours.

[0050] Specifically, the particle sizes of the rice bran superfine powder and the Poria cocos superfine powder in step S2 are 50 to 100 nanometers.

[0051] Specifically, in step S3, the enzymolysis time is 20 to 60 minutes, and the enzymolysis temperature is 40 to 50°C.

[0052] Specifically, in step S4, when the rice bran superfine powder and Poria cocos superfine powder after enzymatic hydrolysis are mixed with freeze-dried hawthorn pieces, 0.5 to 2 parts of natural vanilla powder are added, and the natural vanilla powder includes at least one of mint, lemon and osmanthus powder.

[0053] Specifically, after the final product is obtained in step S5, 0.5 to 1 part of a natural antioxidant is added to the final product, and the natural antioxidant includes at least one of a rosemary extract and a grape seed extract.

[0054] Specifically, the low-temperature drying temperature is 50-60° C., the low-temperature drying time is 2-4 hours, and the humidity is less than 10%.

[0055] From the above, it can be seen that due to the increase in the proportion of rice bran, the taste is slightly bitter, but still acceptable. The mice were fed with this food, and blood tests were taken from the medial canthus vein of the mice before and after the experiment, showing that the lipid-lowering effect was a 22% decrease in total cholesterol (TC), a 25% decrease in triglycerides (TG), a 20% decrease in low-density lipoprotein (LDL-C), and a 15% increase in high-density lipoprotein (HDL-C). Due to the increase in the proportion of rice bran, the lipid-lowering effect was stronger, the food intake and excretion ratio was 1.4, and the digestive capacity was slightly improved.

[0056] Embodiment 3: This embodiment provides a Chinese medicine rice bran edible medicinal composition, comprising: 60 parts of rice bran superfine powder, 30 parts of Poria superfine powder, 20 parts of freeze-dried hawthorn pieces, and 5 parts of natural vegetable oil.

[0057] The natural vegetable oil includes at least one of linseed oil and olive oil.

[0058] A method for preparing a Chinese medicinal rice bran edible composition comprising:

[0059] S1, select high-quality rice husk, after crushing and stabilization treatment, use a mixed enzyme solution of lipase and cutinase to mix with rice bran, and carry out constant temperature oscillation reaction, after the reaction ends, rinse the rice bran with deionized water for many times until the eluate is clarified, and then the rice bran after dewaxing is low-temperature dried to remove excess moisture;

[0060] S2, select high-quality Poria cocos, wash and cut them into pieces, inoculate them with a microbial agent that can decompose bitter substances for fermentation, dry the Poria cocos at low temperature after the fermentation, and grind the rice bran and Poria cocos into nano-scale particles by ultrafine grinding;

[0061] S3, the rice bran superfine powder and the Poria cocos superfine powder after superfine grinding are mixed with cellulase and subjected to short-time enzymolysis treatment;

[0062] S4, mixing the rice bran superfine powder and Poria cocos superfine powder after enzymolysis treatment with freeze-dried hawthorn pieces to obtain a final product;

[0063] S5. After removing excess moisture from the final product by low-temperature drying, the final product is sealed and packaged using vacuum packaging technology.

[0064] Specifically, in step S1, the mixed enzyme solution includes 0.5% to 1% lipase and 0.3% to 0.5% cutinase, the pH value is 6.5 to 7.5, the mixing ratio of rice bran to the mixed enzyme solution is 1:5 to 8 g / mL, the constant temperature oscillation reaction temperature is 45 to 55° C., and the reaction time is 3 to 4 hours.

[0065] Specifically, the particle sizes of the rice bran superfine powder and the Poria cocos superfine powder in step S2 are 50 to 100 nanometers.

[0066] Specifically, in step S3, the enzymolysis time is 20 to 60 minutes, and the enzymolysis temperature is 40 to 50°C.

[0067] Specifically, in step S4, when the rice bran superfine powder and Poria cocos superfine powder after enzymatic hydrolysis are mixed with freeze-dried hawthorn pieces, 0.5 to 2 parts of natural vanilla powder are added, and the natural vanilla powder includes at least one of mint, lemon and osmanthus powder.

[0068] Specifically, after the final product is obtained in step S5, 0.5 to 1 part of a natural antioxidant is added to the final product, and the natural antioxidant includes at least one of a rosemary extract and a grape seed extract.

[0069] Specifically, the low-temperature drying temperature is 50-60° C., the low-temperature drying time is 2-4 hours, and the humidity is less than 10%.

[0070] From the above, we can see that by increasing the proportion of ultrafine Poria powder and combining it with natural vanilla flavor, the overall taste of the product is smoother with a slight licorice aroma. The mice were fed with this product, and blood tests were taken from the inner canthus vein of the mice before and after the experiment. The results showed that the lipid-lowering effect was a 15% decrease in total cholesterol (TC), a 18% decrease in triglycerides (TG), a 12% decrease in low-density lipoprotein (LDL-C), and an 8% increase in high-density lipoprotein (HDL-C). The ratio of food intake to excretion was 1.6, which ensured a relatively mild lipid-lowering effect while improving taste and digestion, making it suitable for users who need to gently regulate blood lipids.

[0071] The composition is composed of superfine rice bran powder, superfine tuckahoe powder and freeze-dried hawthorn pieces;

[0072] Rice bran is the outer skin and germ of rice, rich in dietary fiber, phytosterols, natural antioxidants (such as γ-sitosterol), polyphenols and other substances. Dietary fiber helps lower blood lipids and can reduce its absorption by combining with cholesterol. The phytosterols in rice bran have a structure similar to cholesterol and can competitively inhibit the intestinal absorption of cholesterol, thereby reducing the cholesterol level in the blood. The antioxidant components in rice bran can prevent arterial endothelial damage and slow down the occurrence of arteriosclerosis.

[0073] At the same time, the wax components in the rice bran are removed through the dewaxing process, and the effective ingredients in the rice bran are released, which enhances the solubility of the product and improves its absorption efficiency and bioavailability;

[0074] Poria has the effects of strengthening the spleen, removing dampness, and lowering blood lipids. It can regulate lipid metabolism in the body. The triterpenoid compounds in Poria have antioxidant and anti-inflammatory effects. They can improve liver function, promote lipid metabolism, and reduce fat accumulation in the body. Poria also has a certain antihypertensive effect. It can improve endothelial function and promote blood circulation, thereby enhancing the effect of regulating blood lipids.

[0075] Ultrafine grinding technology is used to process Poria cocos to make its powder more fine, increase its specific surface area, and improve bioavailability;

[0076] By mixing rice bran, Poria cocos and natural plant enzymes for enzymatic hydrolysis, the dietary fiber and phytosterols in the rice bran are released, and the active ingredients in Poria cocos are activated, the release of active ingredients in the raw materials is enhanced, and the overall lipid-lowering effect is improved;

[0077] The flavonoids and organic acids in hawthorn have a significant lipid-lowering effect, which can promote the decomposition and oxidation of fatty acids and inhibit the accumulation of fat. The organic acids in hawthorn (such as malic acid, citric acid, etc.) help improve gastrointestinal function, promote bile secretion, help digestion and absorption of fat, and further reduce blood lipids. Since hawthorn has the effect of dilating blood vessels, it can also promote blood circulation and reduce the burden on the cardiovascular system.

[0078] Rice bran, Poria cocos and hawthorn have complementary lipid-lowering effects. Rice bran is rich in dietary fiber, which can bind to cholesterol and prevent its absorption; Poria cocos enhances the liver's detoxification and excretion functions by regulating lipid metabolism; and hawthorn helps promote fat digestion and decomposition, and improve blood circulation; the combination of the three can synergistically play a role in regulating blood lipids in many aspects, and this combination takes advantage of the "same origin of medicine and food", which can not only ensure the effect, but also will not produce side effects.

[0079] Experimental example: After one week of adaptive feeding, 30 healthy mice were randomly divided into three groups, with 10 mice in each group:

[0080] Experimental group 1: mice were fed with common feed mixed with the edible-medicinal composition nutritional powder prepared in Example 1;

[0081] Experimental group 2, mice were fed with normal diet;

[0082] Experimental group 3: Mice were fed with normal feed mixed with standard lipid-lowering drugs.

[0083] Experimental steps:

[0084] Feeding: The mice were fed with different groups of food (experimental group 1, experimental group 2, and experimental group 3) for 4 consecutive weeks;

[0085] Blood lipid test: Blood was collected from the medial canthus vein of the mice before and after the experiment to test total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C) and other indicators to evaluate the effect of blood lipid regulation;

[0086] Digestive capacity test: The daily food intake and excretion of mice were recorded by weighing method to evaluate digestive efficiency;

[0087] Side effect assessment: The side effects of different groups were assessed by observing indicators such as weight changes, hair condition, and activity level of mice.

[0088] Experimental results:

[0089] Food intake: The food intake of experimental group 1 was similar to that of experimental group 2, but significantly higher than that of experimental group 3, indicating that the composition has advantages in improving appetite and digestion ability;

[0090] Digestive capacity: The digestive capacity of mice in experimental group 1 was significantly improved, as shown by a higher ratio of food intake to excretion, specifically 1.5. The digestive capacity of mice in experimental group 3 was slightly lower, but still improved compared to experimental group 2.

[0091] Blood lipid regulation effect: In experimental group 1, total cholesterol (TC) of mice decreased by 18%, triglycerides (TG) decreased by 20%, low-density lipoprotein (LDL-C) decreased by 15%, and high-density lipoprotein (HDL-C) increased by 12%. Blood lipid indexes were significantly improved, especially in terms of total cholesterol and triglycerides, the effect was close to that of the drug group, but the reduction of LDL-C was smaller, and high-density lipoprotein (HDL-C) increased slightly;

[0092] Side effect assessment: The mice in experimental group 1 had moderate weight gain, shiny hair, good activity, and no obvious side effects; the mice in the drug group had side effects such as weight loss and sparse hair;

[0093] Result analysis:

[0094] Taste: The mice in experimental group 1 showed a strong appetite and did not refuse to eat due to taste issues, indicating that the composition has a significant advantage in taste.

[0095] Lipid-lowering effect: The rice bran edible and medicinal composition of the present invention has a good lipid-lowering effect, which is close to the effect of drugs, but with fewer side effects, and improves digestion ability. It shows better safety and tolerability than experimental group 3, and is more suitable for long-term, daily consumption, lowering blood lipids and improving digestion.
