The probiotic composition provided by the invention scientifically and reasonably uses the composite probiotic powder and the plant active ingredients in a matching manner, can effectively reduce the generation of fat in vivo, and can increase the types and the quantity of probiotic strains and inhibit the growth of harmful bacteria, thereby achieving the selective regulation effect on intestinal flora, improving the stability and the weight-losing effect of the probiotic composition, having remarkable weight-losing effect and being suitable for wide crowds.
The technical scheme of the invention is as follows:
a probiotic composition for losing weight and reducing fat comprises the following components in parts by weight:
10-30 parts of composite probiotic powder, 15-25 parts of plant active ingredients, 8-16 parts of auxiliary protective agents, 20-30 parts of fillers and 1-6 parts of sweetening agents;
the composite probiotic powder is a combination of two or more of bifidobacterium lactis, lactobacillus rhamnosus, bacillus coagulans, lactobacillus casei, lactobacillus acidophilus and lactobacillus bulgaricus; furthermore, the viable count of each probiotic is more than or equal to 1 multiplied by 109 CFU/g;
the plant active ingredients are two or more of chlorogenic acid, bamboo leaf flavone and pachyman.
Furthermore, the plant active ingredients comprise chlorogenic acid, bamboo leaf flavone and pachyman according to the weight ratio of 3-7: 1-5: 11-16.
The composite probiotics are used as main raw materials, and the intake of human body to probiotics can increase the species of intestinal probiotics flora, enhance the colonization ability and the colonization time of endogenous and exogenous probiotics in the intestinal tract of human body, inhibit the growth and the reproduction of harmful intestinal bacteria, especially gram-negative bacteria, fully regulate the composition of the intestinal probiotics flora, regulate the structure of the intestinal flora, relieve obesity symptoms, simultaneously have some functional activities, have health effects, transport activity and certain gastrointestinal tract adhesion, and also have the effects of inhibiting intestinal pathogenic bacteria and regulating immunity.
The invention also compounds natural plant active ingredients, wherein the added chlorogenic acid has specific inhibition effect on glucose-6-phosphatase, can reduce the output of glycogen and inhibit the absorption of glucose by small intestine, 1mM chlorogenic acid can reduce the glucose transport capacity by 80%, and reduce the absorption of glucose by organism, thereby reducing the formation of fat. Experiments prove that when the chlorogenic acid is compounded with the bamboo leaf flavone and the pachyman, the weight of obese rats can be remarkably reduced, and presumably, the compounded plant active ingredient has stronger physiological activity function and has a certain positive effect on promoting the growth of probiotics, so that the proliferation of the probiotics can be promoted, the probiotics function can be better exerted, and meanwhile, the imbalance of intestinal flora can be corrected, and the bacteria causing obesity can be reduced or eliminated.
Furthermore, the probiotic composition for losing weight and reducing fat comprises the following components: 25 parts of composite probiotic powder, 20 parts of plant active ingredients, 12 parts of auxiliary protective agent, 23 parts of filler and 4 parts of sweetening agent.

Test example II Artificial gastric juice resistance test
1. Test materials: the probiotic composition for losing weight and reducing fat is prepared in the examples 1-3 and the comparative examples 1-6.
2. The test method comprises the following steps: respectively putting 0.2g of the probiotic composition prepared in the embodiments 1-3 and the comparative examples 1-6 in 10mL of artificial simulated gastric juice, shaking and uniformly mixing, incubating in water bath at 37 ℃, sampling every 30min, putting in 0.06mol/L sodium citrate solution, shaking for 1h (35 ℃, 100 rpm) to fully dissolve the composition, counting viable bacteria by adopting a plate counting method, and calculating the survival rate.
The formula of the artificial simulated gastric fluid is as follows: 2g of sodium chloride and 3.2g of pepsin are dissolved in 7ml of 1mol/L HCl solution, water is added to 1000ml, and the pH value is measured to be about 2.0 after preparation.
3. Test results
The survival rates of the probiotics in the simulated gastric fluid in the compositions prepared in examples 1-3 of the present invention and comparative examples 1-6 are shown in table 2.
TABLE 2
As can be seen from table 2, in the case of simulated gastric acid, the probiotic compositions prepared in embodiments 1 to 3 of the present invention show good gastric environment tolerance, and after 2 hours in simulated gastric fluid, the survival rate of the probiotic can still reach more than 89%, wherein the best effect of embodiment 2 is the best embodiment of the present invention. In the comparative examples 3-6, when the components of the auxiliary protective agent and the filler are changed, the survival rate of the probiotics in the obtained composition in simulated gastric juice is reduced to different degrees.
