Description

Selenium-rich cordyceps militaris tablet candy and preparation method thereof
Technical Field
The invention relates to a food, in particular to a selenium-rich cordyceps militaris tablet candy and a preparation method thereof.
Background
Cordyceps militaris (Cordyceps militaris) also known as Cordyceps militaris, and Cordyceps militaris can be parasitized on pupa of insects of Coleoptera, Lepidoptera, Diptera, etc., and belongs to genus Cordyceps in phylum Eumycota, subphylum Ascomycotina, class Sclerotia, order Sphaerotheca, Clavicipitaceae, etc. The effect of cordyceps militaris on tumor treatment has been confirmed by a number of studies: the Jagger research in 1961 finds that cordycepin in Cordyceps militaris can prolong the survival time of S180 tumor-bearing mice, and has a certain inhibition effect on tumor growth. Sunkokeng and the like take S180 tumor-bearing mice as research objects, and the finding shows that after cordyceps militaris sporocarp is continuously perfused into the S180 tumor-bearing mice, the growth of tumor mass is obviously inhibited (p is less than 0.01), and the survival time is also obviously prolonged. Research on Guo Yazhuang and Yang penguing shows that the effective rate of treatment of various cancers is 73.5% after treatment by cordyceps militaris.
Selenium is a necessary trace element of human body and is known as 'king of cancer resistance' and 'long life element'. Selenium mainly exists in the form of selenoprotein in human body, and plays a role through selenoprotein, wherein some important enzymes are included, such as glutathione peroxidase (GSH-Px), thioredoxin reductase (Trx R) and the like. Supplementing selenium in appropriate amount can enhance immunity, has positive significance for normal work of organs such as heart, liver and lung, and can also prevent liver disease, cancer and senile cardiovascular and cerebrovascular diseases.
Selenium exists in nature as selenium compound, and the results of a great deal of research prove that the selenium compound plays an important role in the prevention and treatment of tumors. Selenium compounds mainly exist in two forms, inorganic selenium compounds and organic selenium compounds. Inorganic selenium compounds, also called first-generation selenium fortifiers, such as sodium selenite and sodium selenate, were originally found to have good anticancer activity, but as research progresses, disadvantages of inorganic selenium compounds have been gradually developed, for example, inorganic selenium compounds have been found to have disadvantages of cumulative toxicity, mutagenic effect, difficulty in dose control, generation of genetic toxicity, etc., and inorganic selenium compounds have poor biocompatibility and are difficult to enter cells to exert effects. Compared with inorganic selenium compounds, the organic selenium compounds have the characteristics of easy absorption, high activity, relatively low toxicity and the like. Selenocysteine and selenomethionine are two kinds of selenium-containing amino acid, belong to organic selenium compounds, can be actively absorbed by organisms by utilizing the transport mechanism of amino acid and polypeptide in vivo, and have high bioavailability. In recent years, the anti-tumor effect and mechanism of selenomethionine and selenocysteine become a research hotspot.
The selenium-rich cordyceps militaris refers to selenium-enriched cordyceps militaris, and has better antitumor and coordinated antitumor activities compared with common cordyceps militaris. Researches such as Chenjinlin and the like find that 30 cases of selenium-rich cordyceps militaris products are administered to malignant tumor patients, and after the selenium-rich cordyceps militaris products are continuously taken for 2 months, the selenium-rich cordyceps militaris products can inhibit part of tumor growth, resist the toxicity of chemoradiotherapy medicines and improve the survival quality of the patients. The singing and the like adopt the selenium-rich cordyceps militaris extract to observe the in-vivo tumor inhibition effect and the influence on the immune function of the tumor-bearing mice, and as a result, the selenium-rich cordyceps militaris extract has a remarkable tumor inhibition effect on the tumor-bearing mice, the tumor inhibition rate is up to 46.92%, the immune function of the tumor-bearing mice is improved, the reduction of the liver coefficient and the spleen coefficient of the tumor-bearing mice caused by cyclophosphamide is inhibited, and the oxidation resistance of organisms is enhanced. In addition, the selenium form in the selenium-rich cordyceps militaris is mainly organic selenium-selenocysteine and selenomethionine, so that the selenium-rich cordyceps militaris is more beneficial to the absorption and utilization of organisms.
Therefore, the development of the function or the health food by utilizing the anti-tumor effect of the selenium-rich cordyceps militaris has wide prospect.
