The ratio of albumin, gluten, and gliadin in Shiitake mushrooms is 100:63:2, making it the leader in the protein content of vegetables. Among them, 8 of the 18 amino acids that make up the protein in Shiitake mushrooms are essential amino acids. It has a good effect on immunity and promoting bone development.
The content of linoleic acid and oleic acid in dried shiitake mushrooms is as high as 90%, and it is rich in minerals such as calcium, phosphorus, iron, zinc, and manganese, which can improve human immunity. Containing up to 54% of polysaccharides, trehalose, and mannitol, and other substances provide the energy required for human physiological activities, and can also assist fat oxidation. In addition, the pro-vitamin D in mushrooms-ergot alcohol makes up for the lack of this trace element in general vegetables, promotes the absorption of calcium by the human body, and increases the growth rate of children’s bones and teeth.
What are the functions of shiitake mushroom extract?
Lentinan is the main active ingredient of shiitake mushroom (Lentinus edodes) extract. It has physiological functions such as anti-virus, anti-tumor, improving immunity, lowering blood lipids, and lowering blood sugar. It has strong biological activity, high safety, and a wide range of sources. At present, the health function claimed by the special foods of mushrooms approved for registration in my country is to enhance immunity.
Is there a scientific basis for lentinan to enhance immunity?
Studies have shown that lentinan can enhance the non-specific immunity, humoral immunity, and red blood cell immune function of mice. A laboratory study found that lentinan can increase the formation rate of erythrocyte C3b receptor rosette and red blood cell immune complex rosette in normal mice and immunosuppressed mice. The phagocytic activity of macrophages is enhanced, and the antibody titer is increased. Increased, the weight of immune organs increases, and the OD value of lymphocyte transformation increases.
Simply put, shiitake mushroom extract can improve cellular immunity, enhance cell membrane stability, avoid cell pathology, and promote rapid cell repair. Therefore, it can be used as an enhancer and regulator to improve humoral and cellular immunity.
