A method for processing rosaceous kernels includes the steps of preparing a predetermined amount of rosaceous kernels, heating the rosaceous kernels to a predetermined temperature range for a predetermined time, lowering a temperature of the rosaceous kernels to a normal temperature, and making the rosaceous kernels edible for users to intake Vit B17 contained in the rosaceous kernels. Through the heating process, the beta-glucosidase contained in the rosaceous kernels can be destroyed completely, but the Vit B17 still stays in the rosaceous kernels.
