Document Type and Number:
Japanese Patent JP5113978
Kind Code:
B2
Abstract:
As novel salts of monatin, salts with organic amines such as amino acids, aminoalcohols, dipeptide esters, etc. are provided. The salts with amino acids or dipeptide esters can be used as sweeteningmaterials, of which the crystals are stable and highly sweet and are expected to be used as sweetening agents or their ingredients or additionally as sweetening additives to food and drink products. The salts of a mixture of the stereoisomers of monatin with an organic amine form crystals, which provides a method for resolving the stereoisomers of monatin utilizing the difference of their crystallinity or solubility. Providing a method for obtaining the respectively highly pure stereoisomers of monatin, it becomes possible to provide sweetening agents with monatin and food and drink products to which sweetness is given.
