Description

Technical Field

[0001] The invention belongs to the technical field of fat-reducing compositions, and in particular relates to a fat-reducing composition containing plant extract ingredients and a preparation method thereof. Background Art

[0002] With the progress of society and economic development, people's living standards have been significantly improved. At the same time, the pace of life has become faster and faster. In this context, people's daily diet has become more and more diverse and rich, and the intake of various high-fat, high-protein and other nutrients has also increased significantly. However, this excessive energy intake has become one of the main causes of overweight and obesity. The emergence of obesity has significantly increased the probability of health problems such as high blood pressure, high blood sugar, and high blood lipids.

[0003] Among the fat-reducing products currently on the market, most use appetite suppression as the main means. Although this method can effectively control weight in a short period of time, its effect is often only temporary. More seriously, long-term use of these products may cause a series of adverse reactions, such as acid reflux, arrhythmia, diarrhea, anxiety, insomnia and other symptoms. These side effects not only affect people's quality of life, but also make the safety and effectiveness of these fat-reducing products questionable. Therefore, finding a method that can effectively reduce fat while ensuring safety and long-term effects has become an urgent problem to be solved in the current health field. Summary of the invention

[0004] The object of the present invention is to provide a fat-reducing composition containing plant extract ingredients and a preparation method thereof, so as to provide a healthy fat-reducing composition and improve the fat-reducing effect.

[0011] As a preferred technical solution of the present invention, the various dendrobiums contained in the Dendrobium officinale extract lock the volatile substances in the plant extract through the л-л effect, thereby increasing the retention of nutrients in the plant extract. At the same time, the Dendrobium officinale extract regulates blood sugar and fat metabolism, lowers cholesterol and triglycerides in the blood, thereby helping to reduce the synthesis and accumulation of fat in the body.

[0012] As a preferred technical solution of the present invention, pig liver powder and cuttlebone powder provide trace metal elements, lock the volatile components in the plant extracts through chelation, and regulate the endocrine balance of people who want to lose weight.

[0013] As a preferred technical solution of the present invention, in step S2, the mass ratio of material A, sodium alginate, Dendrobium officinale extract and deionized water is 6-8:1-1.5:0.1-0.2:50.

[0014] As a preferred technical solution of the present invention, in step S3, the mass ratio of the pig liver powder, cuttlebone powder, gluconolactone, sucrose fatty acid ester, deionized water, material B, and plant extract is 1-2:1-2:0.05:0.05:200:10-12:30-40.

[0015] As a preferred technical solution of the present invention, the method for preparing the plant extract comprises the following steps:

[0016] A1. Wash fresh okra, put it into an extraction tank, add 10 times the amount of distilled water and boil for extraction three times, combine the extracts, concentrate and dry until the mass proportion of distilled water in the extract is less than 8%, spray dry, crush, and pass through a 100-mesh sieve to obtain an okra extract;

[0017] A2, washing fresh yam, peeling, pressing the pulp, filtering, and extracting the juice to obtain yam extract;

[0018] A3, washing fresh garcinia cambogia, peeling, pressing the pulp, filtering, and extracting the juice to obtain garcinia cambogia extract;

[0019] A4, washing and peeling fresh bitter melon, pressing the pulp, filtering, and extracting the juice to obtain bitter melon extract;

[0020] A5. Wash and slice fresh gourd, immerse in 5 times the amount of distilled water and heat to boiling, continue to cook for 80-100 min, filter, take the liquid phase, and obtain gourd extract;

[0021] A6. Take the okra extract, mountain mushroom extract, garcinia cambogia extract, bitter melon extract, gourd extract, licorice extract (purchased from Xinxiang Bokai Biotechnology Co., Ltd.), ginger extract (purchased from Shaanxi Xinyanghe Biotechnology Co., Ltd.), green tea extract (purchased from Nanjing Zhenweikang Biotechnology Co., Ltd.), cactus extract (purchased from Shaanxi Xinyanghe Biotechnology Co., Ltd.), deionized water, mix, and ultrasonically disperse for 20-30 minutes to obtain the plant extract.

[0022] As a preferred technical solution of the present invention, in step A6, the mass ratio of the okra extract, mountain mushroom extract, garcinia cambogia extract, bitter melon extract, gourd extract, licorice extract, ginger extract, green tea extract, cactus extract, and deionized water is 15-22:20-30:8-10:5-7:2-3:0.6-0.8:0.1-0.3:1-2:1-2:50.

[0023] As a preferred technical solution of the present invention, in step S3, the atomization pressure of the spray drying is 70-90 bar, and the temperature of the spray drying is 80-110°C.

[0024] As a preferred technical solution of the present invention, in step S3, the homogenizing refers to homogenizing at a speed of 3000-4000 r / min for 2-3 min.

[0025] As a preferred technical solution of the present invention, in step A1, the atomization pressure of the spray drying is 100 bar, and the temperature of the spray drying is 120-140°C.

[0026] As a preferred technical solution of the present invention, the phytochemicals contained in the okra extract, such as sticky polysaccharides, oligosaccharides and bioactive peptides, help to lower the cholesterol and triglyceride levels in the blood, thereby reducing the deposition of fat in the blood vessel walls, reducing the accumulation of fat in the body, increasing the body's basal metabolic rate, promoting the oxidative decomposition of fat, increasing satiety, regulating blood sugar levels, and improving the balance of intestinal flora, thereby playing a role in reducing fat;

[0027] The extract of the mountain mushroom contains a variety of organic acids, such as ursolic acid and oleanolic acid, which can promote the decomposition of fat by activating the lipolytic enzyme in fat cells, thereby reducing the accumulation of fat in the body;

[0028] The hydroxycitric acid contained in Garcinia Cambogia Extract can inhibit fat synthesis, promote gluconeogenesis, improve insulin sensitivity, lower blood cholesterol levels, help promote gastrointestinal motility, improve digestive function, promote defecation for people who want to lose weight, and form a good internal circulation;

[0029] Bitter melon extract reduces fat absorption through bitter melon and other fiber components, increases the viscosity of gastric contents and slows digestion to increase satiety, and improves metabolic rate and electrolyte balance through vitamin C and other minerals;

[0030] The vitamin C, carotene and B vitamins in gourd seed extract play an important role in the process of fat loss. Vitamin C is an essential component for the synthesis of carnitine. Carnitine can transfer fatty acids from the cytoplasm to the mitochondria for oxidation and combustion, which can reduce the production of free radicals and protect cells from oxidative stress. Maintaining a healthy immune system helps the body resist disease, thereby reducing the slowing of metabolism and weight gain caused by disease. Carotene can be converted into vitamin A in the body. Vitamins A and B participate in fat metabolism and hormone synthesis, which helps maintain the health of muscles and connective tissues and relieve the problems of loose and wrinkled skin caused by fat loss.

[0031] During the weight loss process, licorice extract is used to regulate blood sugar fluctuations caused by reduced nutrient intake, enhance immune function, regulate water balance in the body, and have anti-stress effects, helping the body cope with the stress and fatigue that may occur during the weight loss process.

[0032] Ginger extract is used to neutralize the side effects of gourd. Gingerol and shogaol in ginger extract have anti-inflammatory and antispasmodic effects, which can relieve gastrointestinal spasms and discomfort, reduce the symptoms of indigestion, and reduce the burden on the digestive system caused by the fiber components in gourd. The antioxidants and anti-inflammatory components in ginger extract can help neutralize the free radical damage caused by gourd intake, reduce inflammatory reactions, and inhibit the stimulation of gastric acid on the stomach wall.

[0033] Green tea extract is used to lower blood lipids, promote metabolism, remove excess oil, refresh the mind and fight fatigue;

[0034] Cactus extract is rich in vitamin C and antioxidants that protect the skin from free radical damage while promoting collagen synthesis, slowing down the skin aging process and keeping the skin firm and smooth.

[0035] The fat-reducing composition containing plant extract ingredients is prepared by the above-mentioned preparation method.

[0036] Beneficial effects of the present invention:

[0037] The present invention discloses a fat-reducing composition containing plant extract ingredients and a preparation method thereof. By optimizing the preparation process, a compound plant extract with fat-reducing effect is added, and okra extract, mountain mushroom extract, garcinia extract, bitter melon extract, gourd extract, licorice extract, ginger extract, green tea extract, and cactus extract are creatively compounded in an appropriate mass ratio to ensure that the various extracts can play a synergistic role and jointly promote human health. Through scientific proportioning, the effective ingredients in each extract can complement each other to achieve the best fat-reducing effect. By utilizing the synergistic effect between okra extract, mountain mushroom extract, garcinia extract and bitter melon extract, the cholesterol and triglyceride levels in the blood can be effectively reduced. These extracts work together to help reduce the accumulation of fat in the body, thereby increasing the body's basal metabolic rate. This increase in metabolic rate promotes the oxidative decomposition of fat, thereby increasing satiety and helping to regulate blood sugar levels. In addition, these extracts can also improve the balance of intestinal flora, thereby playing a fat-reducing role. The synergistic effect of gourd extract and cactus extract can maintain the healthy state of muscles and connective tissues, and effectively alleviate the problems of loose skin and wrinkles that may occur during fat loss. Licorice extract is specially added to regulate the side effects of okra extract, mountain mushroom extract, garcinia extract, bitter melon extract, etc. during weight loss. Licorice extract helps to reduce blood sugar fluctuations, enhance immune function, regulate water balance in the body, and has an anti-stress effect, thereby helping the body cope with stress and fatigue that may occur during weight loss. In order to neutralize the side effects of gourd, ginger extract is added. Finally, green tea extract is specially added to lower blood lipids, promote metabolism, remove excess oil, and have a refreshing and anti-fatigue effect. Through the combined effects of these natural extracts, the fat loss process can be more comprehensively supported while ensuring the health and balance of the body. DETAILED DESCRIPTION

[0122] Performance Testing

[0123] Healthy C57BL / 6J mice aged 4 weeks (average weight 15-16g) were purchased, and after one week of adaptive feeding, they were fed with a high-fat diet for 6 weeks to obtain obese model mice, which were randomly divided into a control group and an experimental group (including Example Groups 1-3 and Comparative Example Groups 1-12), with 10 mice in each group. The control group continued to be fed with a high-fat diet, the experimental group was fed with an equal amount of high-fat diet and fed with the fat-reducing composition prepared in Example 1-3 and Comparative Example 1-12 (10g / kg·d) every day, and the control group was gavaged with the same amount of normal saline. After 5 consecutive weeks, blood was collected from the carotid artery and the heart, and the carotid blood was tested for superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity (using the SODWST-1 method kit and the GSH-Px activity assay kit purchased from Nanjing Jiancheng Bioengineering Institute, and tested according to the kit requirements), and the blood at the heart was tested for TG, TC, HDL-C and LDL-C levels in mouse serum using a fully automatic biochemical analyzer. The weight changes of mice before and after the experiment (measured as the average weight of each group) and the abdominal skin conditions of mice were recorded. There was no statistical difference in the values ​​(P < 0.05), so the average values ​​were taken. See Tables 1-3 for details.
