  • Publication number: 20240360489
    Abstract: Methods of preparing highly purified steviol glycosides are described. The methods include utilizing enzyme preparations and recombinant microorganisms for converting various starting compositions to target steviol glycosides. The highly purified steviol glycosides are useful as non-caloric sweetener, flavor enhancer, sweetness enhancer, flavor stabilizer, flavoring with modifying properties (FMP), foaming suppressor and solubility enhancing agent in consumable products such as any food, beverages, pharmaceutical compositions, tobacco products, nutraceutical compositions, and oral hygiene compositions.
