| Outline of Final Research Achievements |
Poor water solubility of food constituent may lead to a crucial absorption problem. To overcome this problem, the feasibility of recently developed transglycosylated additives, e.g., α-glucosyl hesperidin, α-glucosyl stevia, and α-glucosyl rutin, to improve the dissolution and bioavailability of food ingredient was investigated. We found that trans-glycosylated materials formed self-associated aggregated-nanostructures in aqueous media, and their structure was different among three. The poorly water soluble food compounds could intercorporate the nanostructure, creating nanocomposite structure of hydrophobic food compounds/transglycosylated additives. Moreover, we found that the nanocomposite formation may also protect hydrophobic food compounds from hydrolytic degradation.
