An oral hydrogel carrier for delivering resveratrol into intestine-specific target released with high encapsulation efficiency and loading capacity based on structure-selected alginate and pectin

. Also, this hydrogel carrier provides good protection for RES against the stomach. 94.71% of RES could be transported to the intestines in two hours after oral administration and released mainly in the small intestine and colon. Thus, the hydrogel carrier is conducive to RES, which is absorbed through the intestinal barrier rather than the stomach after oral administration. Moreover, the hydrogel carrier could load other health factors with expected encapsulation efficiencies, such as curcumin (93.52%), ascorbic acid (90.33%), ginsenoside Rg3 (81.54%), and EGCG (92.27%). These also implied that the hydrogel carrier holds general applicability in disease management.
