To provide a cosmetic composition which is foamable when shells are foamed and uniformly mixed with egg white and egg yolk, is efficient when used as it is or when it is used in large quantity, furthermore, it kills harmful fungi, Which is capable of maintaining the carbon dioxide gas in the shell-containing raw egg.SOLUTION: The raw eggs 14 are arranged on a shelf 15 in the container 13 of the carbonic acid gas impregnation apparatus 12, the lid 16 is closed, the flow rate adjusting valve 23 of the discharge pipe 21 is adjusted, and the inflow pipe 18 at a pressure of 0.4 to 1.0 MPa at a pressure of 0.4 to 1.0 MPa for more than 25 hours, the raw egg 14 is impregnated with carbon dioxide gas at 0.4 to 1.0 MPa, and foaming occurs when the shell is broken So that egg white and egg yolk can be stirred and uniformly mixed with carbon dioxide gas impregnated raw egg can be obtained.(FIG.【課題】殻を割ったときに発泡して卵白と卵黄が攪拌されて均一に混ざり、生のまま食する場合や大量に使用する場合の効率が良く、しかも有害菌を死滅させて、鮮度を保持することができる殻付生卵の炭酸ガス含浸方法を提供するものである。【解決手段】炭酸ガス含浸装置12の容器13内の棚15に生卵14を並べ、蓋16を閉じてから放出管21の流量調整バルブ23を調整して、炭酸ガス貯蔵タンク9から流入管18を通して容器13内に0.4~1.0MPaの圧力で25時間以上通流させると、生卵14内に炭酸ガスが0.4~1.0MPaで含浸され、殻を割ったときに発泡して卵白と卵黄が攪拌されて均一に混ざる炭酸ガス含浸生卵を得ることができる。【選択図】図1
