A method for filling, which comprises supplying a barrier layer forming raw material (a barrier material precursor in a gas form) to the inside of a container, irradiating the inside with a high energy ray, to thereby form a barrier layer on the inner surface of the container and at the same time sterilize the inside of the container, and discharging a residual barrier material precursor gas and a by-product gas from the container before or during the filling of a liquid food; and an apparatus for practicing the method. The method allows the formation of a continuous barrier layer covering the edges, glooves, clearances and gaps inside the container, automatic and effective discharge of a residual barrier material precursor gas and a by-product gas from the container through the filling of the liquid food. Further, the method avoids the necessity for using a chemical disinfectant such as hydrogen peroxide, since method comprises sterilizing the inside of a container through the irradiation with a high energy ray and, immediately thereafter, filling a liquid food in aseptic state.
