We study the semileptonic decays of B−→f0(1710,1500,1370)e−νˉe, in which the three f0 states mix with glueball, sˉs and (uˉu+dˉd)/2 states, respectively. By averaging the mixings fitted in the literature, we find that the branching ratios of B−→f0e−νˉe are O(10−6), O(10−6) and O(10−5), respectively, which can be simultaneously observed in experiments at B factories. The large predicted branching rate for B−→f0(1370)e−νˉe would provide a clean mode to directly observe the f0(1370) state.
