Abstract

The invention discloses a preparation method of a zinc-enriched liquid fermentation product of phellinus linteus. The preparation method comprises the following steps: inoculating a phellinus linteus strain onto a liquid seed culture medium added with zinc-enriched yeast and a diaphragma juglandis extract, rapidly culturing with the help of a low-frequency ultrasound with a certain frequency and intensity, inoculating the phellinus linteus liquid strain onto a liquid fermentation culture medium added with zinc-enriched yeast and a plukenetia volubilis leave enzymolysis product and culturing in an ultra-low-frequency magnetic field with a certain frequency and intensity to obtain the zinc-enriched liquid fermentation product of phellinus linteus. According to the preparation method, by the physical-assisted synergistic fermentation of seed liquid and fermentation two-phase low-frequency ultrasound and ultra-low-frequency magnetic fields and the synergistic effect of exogenous additives such as the diaphragma juglandis extract and the plukenetia volubilis leave enzymolysis product, the contents and activities of organic zinc and zinc polysaccharide in final fermentation product of phellinus linteus are significantly increased.

Description

technical field [0001] The invention relates to the field of biological engineering, in particular to a preparation method of a zinc-rich Phellinus linteus liquid fermentation product. Background technique [0002] Phellinus igniarius belongs to the Basidiomycetes subphylum, Strataporia class, Pseudomonas rustaceae, and the genus Necroporus. Phellinus linteus extract has significant effects in clinical applications such as inhibiting cancer cell metastasis and preventing cancer recurrence after surgery. It is currently the most efficient medicinal fungus among the internationally recognized biological cancer drugs. As a large-scale medicinal fungus with the best anti-cancer effect currently internationally recognized, the research on Phellinus linteus on tumor inhibition mainly focuses on the pharmacologically active ingredient Phellinus linteus polysaccharide. [0003] Zinc is a kind of trace element. Its content in the human body and daily intake are very small, but it ca...
