Global food giant Unilever has snapped up Australian ice cream company Weis, the family-run producer of the iconic Mango and Cream Bar.

The Dutch-British consumer goods company said on Wednesday it had entered into a definitive agreement to acquire the Queensland company.

Global consumer goods giant Unilever has acquired another iconic Australian brand.

Unilever already owns the Streets ice cream and more than 400 other consumer brands from around the world, including Lipton, Bushells, Dove, Rexona and Ben & Jerry's.

Les Weis founded Weis in Toowoomba, Queensland, in 1957, and plied local movie-goers with his "Fruito Bars".
