Description

Technical Field

[0001] The invention relates to a full-category dietary fiber powder and a preparation method thereof. Background Art

[0002] Dietary fiber is a polysaccharide that cannot be digested and absorbed by the human gastrointestinal tract and cannot produce energy, but it has a very important physiological role. Studies have shown that more dietary fiber intake can help reduce the risk of obesity and chronic non-communicable diseases, and is associated with a lower risk of all-cause mortality, cardiovascular disease, type 2 diabetes and cancer. According to the 2023 dietary guidelines released by the WHO, adults should consume at least 25g of natural dietary fiber per day. Natural dietary fiber mainly comes from plant foods, such as whole grains, beans, edible fungi, fruits and vegetables, etc. However, with the improvement of living standards, people's food has become more and more refined, the proportion of animal food has greatly increased, and the intake of dietary fiber has decreased significantly, resulting in a significant increase in the incidence of chronic diseases such as diabetes. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a method for preparing a full range of dietary fiber powders, which effectively solves the problems mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: the present invention comprises the following high-fiber raw materials: wheat bran, rice bran, soybean skin, pea fiber, hericium erinaceus, black fungus, dried bamboo shoots, broccoli and yacon, and the mass ratio of the raw materials is 3:3:2:2:2:2:1:1:1.

[0005] The method for preparing the full-category dietary fiber powder of the present invention comprises the following steps:

[0006] 1) Select the following high-fiber raw materials: wheat bran, rice bran, soybean skin, pea fiber, hericium erinaceus, black fungus, dried bamboo shoots, broccoli, and yacon, and weigh them according to the mass ratio of 3:3:2:2:2:2:1:1:1 for use;

[0007] 2) Wash the above raw materials except pea fiber with purified water and drain;

[0008] 3) Mix the above raw materials evenly, and then crush them into 30 mesh particles using a pulverizer;

[0009] 4) Add 5 times the total mass of high-fiber raw materials in pure water according to the mass ratio, and sterilize under high temperature and high pressure at 121.3°C for 20 minutes;

[0010] 5) Add fungal α-amylase and papain, the amount of both enzymes added is 0.05% of the total mass of the high-fiber raw material, and mix them evenly;

[0011] 6) Place in a constant temperature box and perform enzymolysis at 55°C for 12 hours;

[0012] 7) After the constant temperature enzymatic hydrolysis is completed, add whole milk, galacto-oligosaccharide and resistant dextrin immediately, and the added amount is 1% of the total mass of high-fiber raw materials;

[0013] 8) At the same time, add 100 times the total mass of high-fiber raw materials of sterile purified water and mix evenly;

[0014] 9) After the temperature drops to 37°C, add purified water and wash repeatedly for 5 times;

[0015] 10) Place in a dryer and dry at 50°C.

[0016] 11) After drying, the product is crushed into 300-1000 meshes by a pulverizer;

[0017] 12) Thus, a full range of dietary fiber powder with a total fiber content of ≥ 70% is obtained.

[0018] Beneficial effects: This method uses full-category dietary fiber powder obtained from natural diets to adjust the dietary structure by using it as a supplement to the staple food. Clinical studies on patients with type 2 diabetes have shown that supplementing with full-category dietary fiber powder can regulate the intestinal flora of diabetic patients and effectively lower blood sugar.

[0039] Clinical Research

[0040] 1. Research Methods

[0041] 1) Research subjects: Patients with type 2 diabetes were screened in a municipal hospital in Zhejiang Province, and a total of 45 subjects were enrolled, including 25 males and 20 females, evenly distributed between 30 and 70 years old. The subjects had no serious complications or other major diseases.

[0042] 2) Specific operation: All kinds of dietary fiber powder and ordinary flour were mixed in a 1:1 mass ratio to prepare staple food. The subjects consumed the staple food three times a day, with each meal not exceeding 200g, for 2 consecutive weeks. At the beginning and end of the study, 40,000 intestinal bacterial gene fragments were tested for each subject, and Shannon diversity index analysis, principal coordinate analysis (PCoA analysis), and biomarker analysis were performed; at the same time, the two clinical indicators of glycated albumin and glucose tolerance of each subject were compared at the beginning and end of the study.

[0043] 2. Research Results

[0044] 1) Shannon diversity index analysis, reference Figure 1

[0045] The analysis showed that consuming a full range of dietary fiber did not significantly change the flavor index of the intestinal flora in patients with type 2 diabetes, that is, it did not reduce the relative abundance of species in the subjects' intestinal flora.

[0046] 2) PCoA analysis, see Figure 2

[0047] The analysis showed that consuming a full range of dietary fiber powders significantly changed the intestinal flora structure of patients with type 2 diabetes.

[0048] 3) Biomarker analysis, reference Figure 3

[0049] This analysis screened out bacterial groups whose relative abundance was significantly reduced (green) or increased (red) after consuming the full range of dietary fiber powders. The paired test is more sensitive and screens out more groups; the conventional test is more rigorous and screens out fewer groups.

[0050] After determination, the Proteobacteria, Fusobacteria, Pseudomonas, Enterobacteriaceae, Ruminococcus, and Mirabilis, which have been confirmed by a large number of literatures to be closely related to various diseases after their increase, decreased significantly; while the Erysipelothrixales, Prevotellaceae, Rikenellaceae, Porphyromonadaceae, Mistygangella, Faecalibacterium, Prevotella, and Butyrivibrio, which have been confirmed by the literatures to be closely related to various diseases after their decrease or absence, increased significantly.

[0051] 4) Clinical indicator analysis, reference Figure 4

[0052] A before-and-after comparison showed that the blood sugar level of patients with type 2 diabetes dropped significantly after consuming a full range of dietary fiber powder for 2 weeks.

[0053] Beneficial effects: This method uses full-category dietary fiber powder obtained from natural diets to adjust the dietary structure by using it as a supplement to the staple food. Clinical studies on patients with type 2 diabetes have shown that supplementing with full-category dietary fiber powder can regulate the intestinal flora of diabetic patients and effectively lower blood sugar.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
