Energy-supplementing saccharide source

摘要

Trehalose, prepared by the method containing a step of allowing a non-reducing saccharide-forming enzyme to act on a partial starch hydrolysate exhibiting a reducing power, is advantageously used as an energy-supplementing saccharide source and used in energy-supplementing compositions as an effective ingredient. The saccharide source and compositions can be suitably used as pharmaceutical compositions for supplementing energy for living bodies without a fear of causing side effects.
