PCT No. PCT/JP93/01896 Sec. 371 Date Oct. 25, 1994 Sec. 102(e) Date Oct. 25, 1994 PCT Filed Dec. 27, 1993 PCT Pub. No. WO94/14826 PCT Pub. Date Jul. 7, 1994A process is provided which comprises isomerizing a compound having a ketose structure by the use of or in the presence of an organogermanium compound having a structural portion represented by formula (I): IMAGE (I) Due to the use or presence of the organogermanium compound, the process is free from the problems of the prior art, and is capable of isomerizing a compound having an aldose structure into a compound having a ketose structure at a high isomerization ratio without requiring any special apparatus or any complicated operation.
