The present invention maintains the feeling of foaming derived from high-concentration CO2 ice when the high-concentration CO2 ice-containing frozen confectionery is put in the mouth at the time of eating, while providing an unpleasant foaming feeling derived from high-concentration CO2 ice and a gas odor of aftertaste. An object of the present invention is to provide a high-concentration CO2 ice-containing frozen dessert that suppresses the above, a method for producing the high-concentration CO2 ice-containing frozen dessert, and the like. In the manufacture of frozen dessert containing ice having a CO2 content of 3% by weight or more, the frozen dessert contains an oil or fat having a melting point of 10 ° C. or less. Preferred examples of ice having a CO2 content of 3% by weight or more include CO2 hydrate.本発明は、喫食時に高濃度ＣＯ２氷含有冷菓を口内に入れた際の、高濃度ＣＯ２氷由来の発泡感を保持しつつ、高濃度ＣＯ２氷由来の不快な泡立ち感や、後味のガス臭さを抑制した高濃度ＣＯ２氷含有冷菓や、該高濃度ＣＯ２氷含有冷菓の製造方法等を提供することを目的とする。ＣＯ２含有率が３重量％以上の氷を含有する冷菓の製造において、融点が１０℃以下の油脂を前記冷菓に含有させることを特徴とする。ＣＯ２含有率が３重量％以上の氷としては、ＣＯ２ハイドレートが好ましく挙げられる。
