We study the semileptonic decays of B-→ f₀(1710,1500,1370) e- νₑ, in which the three f₀ states mix with glueball, s s and (u u+ d d)/√ 2 states, respectively. By averaging the mixings fitted in the literature, we find that the branching ratios of B-→ f₀ e- νₑ 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- νₑ would provide a clean mode to directly observe the f₀(1370) state.
