The prevent invention provides a novel gas treatment method for a fluid, and a method for producing a milk using the same, which is industrially extremely advantageous in terms of cost and efficiency. n A gas treatment method for a fluid, comprises, while discharging a fluid from a fluid discharge port 161 of a two-fluid nozzle 160, crushing the discharge flow into fine droplets by a gas stream from a gas injection port 162, and then allowing the droplets to strike against a flow prevention member 190 and thereby agglomerate, so as to perform a gas treatment (gas addition, gas replacement, deaeration, or sterilization (disinfection)). According to the method for producing a milk, nitrogen is used as the gas stream, whereby homogenization and nitrogen replacement of dissolved oxygen can be performed in one and the same process. |
