1. A method for processing dandelion plant components (10), more particularly dandelion plant components of the species Taraxacum kok-saghyz, wherein obtaining of rubber as a first valuable product is achieved in the method and is characterized by the following steps: comminution and/or squeezing of the dandelion plant components (10), preferably with addition of water (30), to form a slurry (60);first separation (70) of the slurry (60) into at least one high-inulin low-rubber phase (80, 80′) and at least one high-rubber low-inulin phase (90, 90′), wherein the high-rubber low-inulin phase (90, 90′) forms the first valuable product or the first valuable product is obtained from the high-rubber low-inulin phase (90, 90′),wherein at least step A) is done at a temperature of less than 40° C. 2.
