ABSTRACT:
Non-reducing saccharides including alpha-glycosyl trehaloses, alpha-glycosyl alpha-glycosides and trehalose are easily produced by cultivating microorganisms capable of producing non-reducing saccharide-forming enzyme in nutrient culture media which contain reducing partial starch hydrolysates with glucose polymerization degrees of 3 or higher. The yields for these saccharides are significantly improved by further subjecting the reducing partial starch hydrolysates to starch-debranching enzyme and/or cyclomaltodextrin glucanotransferase in or not in culture media. The resultant non- or less-reducing saccharides commonly bear desirable properties in addition to a mild and gentle sweetness. Thus they would find extensive uses in a variety of compositions including food products, cosmetics and medicines.
