An object of the present invention is to provide a bubble with tofu made with easy interference tofu seasoning liquid is bleeding. A drought which has been made in view of the seasoned tofu 1, by immersion in aqueous sodium bicarbonate solution was boiled tofu 1 NOTE, decomposing the interference tofu 1, by draining compression, interference create a large number of bubbles 2 and layer inside tofu 1, it is changed to a sponge-like. It is possible to maintain the flavor components of the liquid seasoning and promotion of impregnation and will, unlike to add the process to the production process of tofu, to enable the equipment is what simple reduction of observed cost.FIELD 4【課題】調味液が滲み易い干豆腐で作った気泡付き豆腐を提供する。【解決手段】干豆腐1の味付けに着目してなされたもので、干豆腐1を沸騰した重曹水に浸すことで、干豆腐1を分解し、水切り圧縮をすることで、干豆腐1内部に多数の気泡2と層を作り、スポンジ状に変化させる。調味液の旨味成分を含浸の促進と維持することが可能となり、豆腐の製造工程に処理を加えるのと異なり、設備が簡単なものですみコストの削減を可能とする。【選択図】図4
