Description

Compound nutrient composition with antioxidant function
Technical Field
The invention relates to the field of medicine and health care, and relates to a compound nutrient preparation with an antioxidant function and a preparation method thereof.
Background
Free radicals are chemical substances, also called active oxygen, which are very active and have strong oxidation effect and are generated by human cells in the metabolic process. Free radicals are ubiquitous in the human body, and the attack routes are also multifaceted. When the free radicals in the human body exceed a certain amount and lose control, the free radicals run and flee, attack cell membranes, oxidize serum antitrotease, even grab electrons of DNA, damage healthy cells of the human body, and induce diseases such as cardiovascular diseases, diabetes, age-related macular degeneration, cancers and the like. In addition, the damage of the different cells by free radicals can lead to the degeneration of seemingly unrelated diseases, so that the cells cannot absorb nutrients from the outside, cannot discharge intracellular metabolites and lose the defense against cells and viruses. Reducing the immunity of human body, so that some people are called as the source of 'ten thousands of diseases' by free radicals.
Aging of the human body is also inseparable from free radicals. United kingdom pioneered in 1956 the association of free radicals with body ageing and disease, followed by a first study report in 1957 demonstrating that mice fed with feed containing 0.5% to 1% free radical scavenger have an extended lifespan. The central content of the theory of free radical aging is that aging results from the random and destructive action of free radicals generated in the normal metabolic processes of the body. The causes of aging of the body caused by free radicals in the human body can be summarized into three aspects: cross-linking polymerization of living macromolecules and lipofuscin accumulation; destruction and reduction of organ tissue cells; and simultaneously, the immune function is reduced, thereby causing diseases and aging of the human body.
The formation of free radicals in the human body is ubiquitous, and the generation of free radicals is promoted by sunlight, radiation, ozone, and the like. In daily life, free radicals may come from outside the body or from inside the body. Free radicals can be induced by in vitro sources such as smoking, sun exposure, food preservatives, pesticides, chemical carcinogens (e.g., certain drugs, plastics, etc.), pesticides, radiation, etc. Scientific research shows that smoking is the fastest and most free radical generating mode at present, more than one hundred thousand free radicals can be generated after smoking each cigarette, systemic cancer can be caused, and the growth of cancer cells, particularly lung cancer, can be accelerated. It also causes a number of chronic diseases, such as cardiovascular disease and diabetes. Excessive mental stress can also induce excessive formation of free radicals in vivo when the mood fluctuates sharply.
In recent years, research on free radicals and free radical scavengers is active at home and abroad, and many research reports on free radicals and scavengers thereof are reported in various food sciences, life sciences and medical books.
In the prior art, grape seed extract, tea polyphenol and selenium-enriched yeast as functional components can be added into food, feed and other products at the same time, for example, CN104982723A discloses a feed premix; CN108142763A and CN108433107A disclose drinking water added with functional components; CN109156603A discloses a compound premix feed. Although these prior arts contain the above antioxidant component, since the use of selenium has an upper limit (safety problem) in human body, the addition amounts of grape seed extract and tea polyphenol are limited in the technical solutions of CN104982723A, CN108142763A and CN108433107A when the content of selenium is limited. In addition, the above prior arts all study the dosage ratio of the three components. The application further researches the dosage and the proportion of the three components to find that the three components can achieve better antioxidant effect in a specific proportion.

As can be seen from Table 3-1, compared with the blank control, the serum MDA content in the serum of the aged mice of the comparative groups 1 and 2 is significantly reduced (P is less than 0.05), and the serum MDA content in the serum of the aged mice of the comparative groups 4 and 5 is significantly reduced (P is less than 0.001); compared with the comparison groups 1-4, the serum MDA content of the mice of the comparison group 5 is obviously reduced (P is less than 0.05). Compared with a blank control, the SOD activity in the serum of the mice with the age of 1 to 4 in the comparison group is obviously improved (P is less than 0.05), the SOD activity in the serum of the mice with the age of 5 in the comparison group is obviously improved (P is less than 0.001), and compared with the blood serum of the mice with the age of 5 in the comparison group is obviously improved (P is less than 0.001) in the comparison group 1 to 4. Compared with a blank control, the activity of the GSH-Px in the serum of the aged mice of the comparison groups 1, 2 and 4 is obviously improved (P is less than 0.05), and compared with the comparison groups 1 to 4, the activity of the GSH-Px in the serum of the aged mice of the comparison group 5 is obviously improved (P is less than 0.001).
4. Conclusion of the experiment
The MDA content reflects the severity of free radical attack on the organism, and after the organism is attacked by the free radical, lipid peroxidation is initiated, and MDA is further generated. SOD plays a crucial role in the balance of oxidation and antioxidation of the body, and the enzyme can remove O2 -Protection of cells from damage, the magnitude of SOD activity indirectly reflects the ability of the body to scavenge oxygen free radicals. The activity of GSH-Px reflects the reducing power of tissues and serum in a mouse, and the level indirectly reflects the elimination capability of the mouse to free radicals. 5 tested samples of grape seed extract plus tea polyphenol, grape seed extract plus selenium, tea polyphenol plus selenium, grape seed extract plus VE plus selenium, grape seed extract plus tea polyphenol plus selenium are orally administered to old mice. The test sample combined with other 4 groups of test samples, namely the grape seed extract, the tea polyphenol and the selenium can obviously reduce the MDA content in the serum of the mouse, and improve the activity of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD). The grape seed extract, the tea polyphenol and the selenium are compounded for use, the antioxidant effect is better than that of the combination of the grape seed extract, VE and the selenium, and the synergistic antioxidant effect is achieved.
