The invention discloses a method for producing β-glucan, which comprises obtaining a yeast sample and using a temperature gradient method (firstly treating at 75-90 ° C for 1-2 hours, then rapidly cooling to 55-65 ° C for 0.5 treatment). -1 hour) The alkaline solution is treated with an acidic solution, and then the fat is removed with ethanol, and finally dried to obtain β-glucan. After each treatment step, after centrifugation, washing with water, the precipitate is centrifuged again for the next treatment step. The manufacturing method of the invention has the advantages of rapid, simple steps and no residual risk of organic solvents, and can obtain high-purity glucan, which can be used for health foods, animal immunity products and cosmetics. |
