20130011538 | CRYSTAL OF MULTIVALENT METAL SALT OF MONATIN - To provide a novel monatin crystal capable of forming a sweetener composition which is less likely to be degraded even when being exposed to high temperature and high humidity conditions in the coexistence of a reducing sugar. It was found that the object can be achieved by a crystal of a multivalent metal salt of (2R,4R)-monatin. | 01-10-2013 |
20130164792 | METHOD FOR PRODUCING CRYSTALS OF MUTIVALENT METAL SALT OF (2R, 4R) MONATIN - The present invention provides a method of efficiently producing a crystal of a (2R,4R)Monatin multivalent metal salt that has a good sweetness property and is excellent in storage stability. Specifically, the present invention provides the method of producing the crystal of the (2R,4R)Monatin multivalent metal salt comprising allowing an aldehyde or one or two or more enzymes capable of forming (2R,4R)Monatin from (2S,4R)Monatin to be acted on an aqueous solution containing the (2S,4R)Monatin in the presence of a multivalent metal ion to obtain the crystal of the (2R,4R)Monatin multivalent metal salt. The aldehyde may preferably be an aromatic aldehyde. The one or two or more enzyme may preferably be a racemase or one or more aminotransferases. The multivalent metal may preferably be a bivalent alkaline earth metal. | 06-27-2013 |
20140234916 | METHOD FOR PRODUCING MONATIN USING AN L-AMINO ACID AMINOTRANSFERASE - The present invention provides a methodology for improving a yield of 2R,4R-Monatin. Specifically, the present invention provides a method for producing 2S,4R-Monatin or a salt thereof, comprising contacting 4R-IHOG with an L-amino acid aminotransferase in the presence of an L-amino acid to form the 2S,4R-Monatin; a method for producing 2R,4R-Monatin or a salt thereof, comprising isomerizing the 2S,4R-Monatin to form the 2R,4R-Monatin; and the like.
