PROBLEM TO BE SOLVED: To provide a device for sterilization of products such as foods and cosmetics in a viscous fluid state, eliminating or inhibiting degeneration of a temperature-sensitive compound contained in the products at least to a minimum.SOLUTION: A divice for preparation and sterilization of a viscous fluid (10) which contains an aseptic temperature-sensitive compound (11) diluted in a viscous matrix (12) includes heat treatment units (15,45 and 55) in which the viscous matrix (12) is supplied to be sterilized. The device further includes a mixing unit (17) in which the sterilized viscous matrix (12) and the aseptic temperature-sensitive compound (11) are supplied. The aseptic temperature-sensitive compound (11) is mixed with the sterilized viscous matrix (12) in the mixing unit, so as to produce the viscous fluid (10).COPYRIGHT: (C)2016,JPO&INPIT【課題】粘性流体の形態をした食品や化粧品のような製品の滅菌にあたり、かかる製品に含まれる温度感受性配合物の変性をなくし又は少なくとも最小限に抑える。【解決手段】粘性マトリックス(12)中に希釈された無菌の温度感受性配合物(11)を含む粘性流体(10)の調製及び滅菌のための装置は、粘性マトリックス(12)が供給される熱処理ユニット(15,45,55)を有し、粘性マトリックス(12)は、熱処理ユニット内で滅菌され、この装置は、滅菌済み粘性マトリックス(12)及び無菌の温度感受性配合物(11)が供給される混合ユニット(17)を更に有し、無菌温度感受性配合物(11)は、混合ユニット内で滅菌済み粘性マトリックス(12)中に混ぜ込まれて粘性流体(10)が生じる。【選択図】図1
