Problems solved by technology

However, prebiotics (such as fructooligosaccharides) widely used in the market today are very expensive
Moreover, if it is directly added to food, it may chemically react with other components in the food, reducing the shelf life of the food, and the conditions required for separate storage are relatively harsh.

Embodiment 1

[0034] Embodiment 1: mouse feed preparation

[0035] Feed preparation method of the present invention such as figure 1 shown.

[0036] Sodium selenite is dissolved in deionized water, then mixed with the feed, and granulated. The detailed method is as follows: Weigh 0.15, 0.40, 1.00 and 2.00mg of sodium selenite respectively, dissolve in 200mL of deionized water, pour into 1kg of feed material, mix and granulate. The mouse feeds with selenium content of 0.15, 0.40, 1.00 and 2.00 mg / kg were formed, and named as control group, selenium-enriched group, high-selenium group and extremely high-selenium group respectively. They are equivalent to human intake of 50, 200, 400 and 800ug / d. The composition of the basic feed is shown in Table 1 and Table 2 below:

Embodiment 2

[0041] Example 2: Effect of trace element selenium dietary supplement on intestinal flora of mice

[0042] Forty four-week-old SPF mice were randomly divided into 4 groups, 10 in each group. The groups were control group, selenium-enriched group, high-selenium group and extremely high-selenium group. Each group was fed with feeds containing 0.15, 0.40, 1.00 and 2.00 ppm selenium, respectively. The mice had free access to food and water, and the experimental period was 2 months. Feces from each mouse were collected at the end of the two months. Genomes from mouse feces were extracted using a Fecal DNA Extraction Kit (Omega Bio-tek, Norcross, GA, U.S.). And use PCR to amplify the V4V5 region in bacterial 16SrRNA. The amplification primers are 515F (5'-barcode-GTGCCAGCMGCCGCGG-3', the sequence shown in SEQ ID NO: 1), 907R (5'-CCGTCAATTCMTTTRAGTTT-3', the sequence shown in SEQ ID NO: 2). The amplification primers were purified by electrophoresis, and the purified products wer...

Embodiment 3

[0053] Example 3: Effects of trace element selenium dietary supplements on the antioxidant capacity of mice

[0054] According to the mouse experiment described in Example 1, after the end of the experiment, the mice were killed by taking blood from the orbit, and the liver and kidneys of the mice were taken, washed with pre-cooled physiological saline, and homogenized. Determination of antioxidant indicators such as SOD (superoxide dismutase), MDA (malondialdehyde) and T-AOC (total antioxidant capacity) in the liver. The test results are shown in the table below.

[0055] Table 5 Determination of antioxidant activity in mouse liver

[0056]

[0057] Note: * indicates that there is a significant difference between this group and the control group, p<0.05; ** indicates that there is a very significant difference between this group and the control group, p<0.01.

[0058] It can be seen from the data in Table 5 that the antioxidant capacity of the selenium-enriched group and...

Abstract

The invention discloses a microelement selenium dietary supplement with a function of regulating intestinal flora and an application thereof and belongs to the technical field of food. According to the invention, when the dosage of the microelement selenium dietary supplement reaches up to the level of a selenium-rich group and a high-selenium group, the intestinal microorganisms in the body can be obviously improved and the relative abundance of probiotics, such as lactobacillus and bifidobacterium, can be obviously promoted, and the relative abundance of pathogenic bacteria, such as enterobacteriaceae and fusobacterium, can be obviously reduced. The microelement selenium dietary supplement can effectively promote the antioxidant ability of the body and has a wide application prospect.

Description

technical field [0001] The invention relates to a trace element selenium dietary supplement with the function of regulating intestinal flora and an application thereof, belonging to the technical field of food. Background technique [0002] The intestinal tract is the largest digestive organ in the human body, and it is also the largest detoxification organ in the human body. Therefore, the health of the intestinal tract directly determines the health of the human body. Closely related to intestinal health is the ecological balance of intestinal flora. A wide variety of microorganisms live in the intestines of healthy people, and these microorganisms constitute a huge and complex micro-ecosystem. Currently, more than a thousand genera have been found in intestinal microorganisms, and the total number is about 10. 13 indivual. A stable intestinal flora can effectively help the human body digest food and absorb nutrients, secrete vitamins through its own metabolism and antag...
