A straw-in-straw degassing unit for degassing liquid formulas and compositions, and pouches and dispensing containers including the degassing unit. A straw-in-straw degassing unit is comprised of an outer tube and includes a first outer tube aperture at a first outer tube location and a second outer tube aperture at a second outer tube location. An inner tube is slidably nested within an interior of the outer tube, and includes a first inner tube aperture and a buoyant element coupled to the inner tube. The inner and outer tubes slidably interact, with changes in a gravitational orientation of the degassing unit, for conditional alignment of apertures therebetween and degassing of liquid formulas and compositions; in this manner, a liquid can be expulsed from a container without substantial expulsion of gas therefrom.
