The invention discloses a method for prolonging the shelf life of honey, and relates to the technical field of preservation of bee products. The method comprises the following steps: A, fresh liquid honey is collected and filtered, pure honey is obtained, and 0.05-0.1 parts by weight of glucose juice is added to the pure honey and stirred uniformly, wherein the ratio of glucose to purified water in the glucose juice is 1:1; B, the pure honey with the glucose juice added is placed at the temperature of 5-10 DEG C for 12-24 h to be condensed into crystal honey; C, the crystal honey is preserved at the temperature of 12-18 DEG C. Compared with the prior art, the method can solve the problem of short shelf life of the conventional natural honey.
