The invention discloses a stir-frying method of melon seeds with tastes of mint and lemons. The stir-frying method comprises the following steps: soaking melon seeds in lime liquor, and then soaking the melon seeds soaked in the lime liquor in salt water so as to obtain the first-time soaked melon seeds; adding the first-time soaked melon seeds into boiling water, adding lemon juice into the boiled water, soaking the first-time soaked melon seeds in the mixture of the lemon juice and the boiled water, adding mint powder into the mixture of the lemon juice and the boiled water, and soaking the first-time soaked melon seeds in the mixture of the lemon juice, the boiled water and the mint powder so as to obtain second-time soaked melon seeds; adding the second-time soaked melon seeds into the water, adding spice packages into the water, cooking the second-time soaked melon seeds in the mixture of the spice packages and the water, taking the cooked second-time soaked melon seeds out of the mixture of the spice packages and the water, and draining water so as to obtain third-time soaked melon seeds; adding table salt, xylitol and isomaltooligosacharide into the water, heating the mixture of the table salt, the xylitol, the isomaltooligosacharide and the water, and soaking the third-time soaked melon seeds in the heated mixture of the table salt, the xylitol, the isomaltooligosacharide and the water so as to obtain fourth-time soaked melon seeds; putting the fourth-time soaked melon seeds into a baking oven, and baking the fourth-time soaked melon seeds for two times, wherein the temperature of the first-time baking is 105-110 DEG C, the time of the first-time baking is 30-50min, the temperature of the second-time baking is 60-80 DEG C, and the time of the second-time baking is 1-2.5h; then performing microwave treatments so as to obtain microwaved melon seeds, wherein the power is 800-1000W, and the time is 15-30s; and stir-frying the microwaved melon seeds.
