Methods of preparing highly purified steviol glycosides, particularly steviolmonoside, steviolmonoside A, steviolbioside, steviolbioside D, rubusoside, steviolbioside A, steviolbioside B, rebaudioside B, stevioside, rebaudioside G, stevioside A, stevioside B, stevioside C, rebaudioside A, rebaudioside E, rebaudioside E2, rebaudioside E4, rebaudioside E6, rebaudioside E3, rebaudioside D, rebaudioside 1, rebaudioside AM, rebaudioside D7, rebaudioside M, rebaudioside M4, rebaudioside 1a, rebaudioside 1b, rebaudioside 1c, rebaudioside 1d, rebaudioside 1e, rebaudioside 1f rebaudioside 1g, rebaudioside 1h, rebaudioside 1i, rebaudioside 1j, rebaudioside 1k, rebaudioside 1l, rebaudioside 1m, rebaudioside 1n, rebaudioside 2a and/or SvG7 are described. The methods include utilizing enzyme preparations and recombinant microorganisms for converting various staring compositions to target steviol glycosides. The highly purified steviol glycosides are useful as non-caloric sweetener, flavor enhancer, sweetness enhancer, and foaming suppressor in edible and chewable compositions such as any beverages, confectioneries, bakery products, cookies, and chewing gums. |
