PROBLEM TO BE SOLVED: To provide a method and device which can fill the pouch with even an easily bubbling liquid content while suppressing generation of bubbles and obtain the pouch filled with a spout with a high deoxidization ratio. SOLUTION: In the method for filling and sealing the liquid content, a deoxidization step before filling 1 including a vacuum step 1-1 that a gas in a pouch is evacuated by vacuum before filling the liquid content, an inert gas blowing step 1-2 that an inert gas is blown into the pouch after the vacuum step and a gas decreasing vacuum step 1-3 that the gas in the pouch is decreased to a predetermined quantity by vacuum evacuation after the inert gas blowing step, is performed before filling the liquid content. After that the inside of the pouch is evacuated in the second evacuation step 2-1 before filling and the content is filled and further after the filling an inert gas replacement is performed.
