ファットブルーム

ファットブルーム(fat bloom)はチョコレートに生じる劣化現象の一つである。オイルブルーム、ブルーム現象とも言われている。

現象および原因

  • チョコレートに含まれるココアバターが温度の上昇により製品表面に溶け出し、白い結晶となって浮き出てくる[1][2]。指で触ると結晶が溶けるため、湿気によって砂糖が再結晶化した「シュガーブルーム」やカビなどと見分けることが出来る。
  • 賞味期限に関わりなく、温度変化により生じるので、冷暗所で保管することが望ましい。また、再度テンパリングすることにより、元に戻すことができる。
  • 風味や口溶けは損なわれるが、身体への影響はない[1]

This is a list of metro systems which were built under the Soviet Union and kept on working in the post-Soviet states. There were 13 metro systems in 7 of the 15 Soviet republics just before the dissolution of the Soviet Union in 1991. A 14th metro system, the Dnipro Metro, started construction in 1982, but due to financial difficulties was not opened until 1995. Other than in Dnipro, the only metro systems built in the post-Soviet states after 1991 are Kazan Metro in Russia (2005) and Almat...
