The invention discloses a preparation method and application of yeast beta-glucan functionalized nano-selenium, and the method comprises the following steps: step 1, mixing a yeast beta-glucan solution and a sodium selenite solution, and stirring for 0.5-2 hours, so that the yeast beta-glucan solution and the sodium selenite solution are uniformly mixed to obtain a mixture; a yeast beta-glucan sodium selenite mixed solution is obtained; step 2, adding an ascorbic acid solution into the yeast beta-glucan sodium selenite mixed solution, and reacting for 0.5-3 hours under the conditions of normal temperature and light resistance, so as to obtain a yeast beta-glucan nano-selenium mixed solution; and step 3, performing dialysis treatment on the yeast beta-glucan nano-selenium mixed solution in pure water to obtain a purified yeast beta-glucan nano-selenium solution, and performing freeze drying on the yeast beta-glucan nano-selenium solution to obtain the yeast beta-glucan functionalized nano-selenium powder.
