METHOD FOR PRODUCING 4-HYDROXY-2(OR 5)-ETHYL-5(OR 2)- METHYL-3(2H)-FURANONE

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing 4-hydroxy-2(or 5- ethyl-5(or 2)-methyl-3(2H)-furanone (HEME) with a yeast in a high production amount, such as a high production amount of ≥100 ppm, by using a liquid culture medium having a simpler culture medium composition comprising a pentose, glucose, an amino acid, salt, and so on without using a soy sauce Koji-digested liquid, a protein hydrolyzate or the like. ;SOLUTION: This method for producing 4-hydroxy-2(or 5)-ethyl-5(or 2)- methyl-3(2H)-furanone comprises heating a liquid culture medium containing at least a pentose such as ribose as a carbon source and an amino acid as a nitrogen source in the coexistence of the pentose and the amino acid, inoculating and culturing a salt-resistant yeast having a HEME-producing ability, such as Zygosaccharomyces rouxii, in the liquid culture medium, and then collecting the HEME from the culture product. The amino acid is preferably alanine or glycine.;COPYRIGHT: (C)2001,JPO
