Description

Technical Field

[0001] The invention relates to the field of chemistry, in particular to a flaxseed composition capable of reducing triglyceride and helping to prevent obesity and a preparation method thereof. Background Art

[0002] In March 2024, the World Obesity Federation released the World Obesity Atlas 2024. By 2035, it is estimated that there will be nearly 3.3 billion overweight and obese adults in the world, accounting for 54% of the total population. Modern research has found that many non-communicable chronic diseases are basically related to obesity, and hyperlipidemia is one of them. Obesity and hyperlipidemia have become serious public health problems worldwide; hyperlipidemia is not only a risk factor for cardiovascular disease, but also closely related to a variety of metabolic diseases; therefore, it is particularly important to develop a food or health product that can effectively reduce triglyceride levels and assist in obesity prevention. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In view of the shortcomings of the prior art, the present invention provides a composition with flaxseed as the main component, which significantly reduces triglyceride levels and effectively prevents the occurrence of obesity by rationally matching other components (buckwheat and oligosaccharides). The experimental results show that 80 hyperlipidemia patients have significantly improved important indicators such as triglycerides, high-density lipoprotein cholesterol, body weight, and BMI by daily consumption of the composition during the 56-day intervention period.

[0005] (II) Technical solution

[0006] To achieve the above object, the present invention provides the following technical solution: a flaxseed composition having the function of reducing triglycerides and helping to prevent obesity, the composition comprising the following components: flaxseed: 30%-90%; bitter buckwheat: 10%-40%; oligosaccharides: 0%-50%.

[0007] Preferably, the content of the flaxseed is 65%; the flaxseed is screened and washed to remove impurities, and is low-temperature dried at a temperature not exceeding 80°C to maintain the activity of its effective ingredients. The flaxseed used is a variety with an α-linolenic acid content of not less than 20% and a dietary fiber content of not less than 20%.

[0008] Preferably, the content of tartary buckwheat is 20%; the tartary buckwheat is shelled tartary buckwheat, which is ground to increase its bioavailability. The tartary buckwheat variety selected is rich in dietary fiber, flavonoids and polysaccharides, which can effectively improve the lipid-lowering effect of the overall composition.

[0009] Preferably, the content of the oligosaccharide is 15%; the particle size of the oligosaccharide is 40-60 mesh, and the oligosaccharide is selected from oligofructose or oligogalactose, which has the function of promoting intestinal health and regulating intestinal microbial flora. The oligosaccharide should be extracted from plant fiber by hydrolysis or from microbial fermentation to ensure that it has good solubility and biological activity.

[0010] Preferably, the composition can be used to reduce triglyceride levels and prevent obesity; the composition can be prepared in the form of powder, granules or dietary supplements, which is convenient for daily use by consumers. The recommended intake of each composition is 60g, which is suitable for two intakes per day.

[0011] A method for preparing a flaxseed composition having the effect of lowering triglycerides and helping to prevent obesity comprises the following steps:

[0012] Mix flax seeds and bitter buckwheat in the ratio described in claim 1; grind and screen, the carbohydrates in bitter buckwheat can absorb the oil precipitated from the flax seeds, and ensure that the ingredients are fully and evenly mixed; mix the mixture with oligosaccharides in the ratio described in claim 1,

[0013] Before mixing, the flaxseed and the bitter buckwheat are cooked separately, and the flaxseed is cooked by steam and dried by boiling. Preferably, the duration of the steam cooking is 0.5-1.5 hours, and the temperature of the boiling drying treatment is 60-80°C, and the duration is 0.5-2 hours. The temperature should be continuously monitored to ensure that it does not exceed 80°C to prevent the unsaturated fatty acids in the flaxseed from oxidizing. The bitter buckwheat is cooked by puffing, and preferably, the puffing cooking temperature is 150-200°C.

[0014] Preferably, the equipment used in the pulverizing step is a high-speed pulverizer, which should have an adjustable speed function, and the pulverizing speed range is 5000-10000 rpm, so as to be adjusted according to the hardness of different ingredients. The pulverizing time should be controlled within 5-10 minutes to prevent excessive pulverization from causing ingredient loss.

[0015] During the screening process, a 20-40 mesh screen is used to ensure uniform particles, which is convenient for subsequent uniform mixing; a screen with too large a mesh number is not conducive to effective component separation, and a screen with too small a mesh number will form a mass and block the aperture, which is not conducive to continuous production and. The optimal mesh number is conducive to protecting the loss of nutrients during processing and can also improve the fluidity and stability of the product.

[0016] The composition and the preparation method thereof are used for manufacturing health food or nutritional supplement.

[0017] Preferably, the composition can be formulated with other nutrients (such as vitamins, minerals, prebiotics, etc.) to enhance the overall nutritional value. It is recommended to prepare it in the form of complementary food, tablets or powders, so that consumers can choose according to their needs; the product should indicate the indications, usage and recommended dosage, and conduct clinical trials to verify its safety and effectiveness.
