Abstract:
In present study, HEP was successfully encapsulated into the Poly (lactic-coglycolicacid) (PLGA) to constitute the HEP-PLGA. The effects of three independent factors (the proper range of ratio of organic phase (o) to internal water phase (w1) (X1), ratio of external water phase (w2) to the primary emulsion (PE) (X2), and the concentration of PLGA (X3) on the extraction yield of encapsulation efficiency (EE) from the HEP was optimized using response surface methodology. The optimal extraction conditions for HEP-PLGA were determined as follows: X1: 8:1, X2: 7:1 and X3: 20 mg·mL⁻¹. Under these optimal conditions, the mean experimental EE 90.86 ± 0.576% was corresponded well with the predicted value of 91.81%. In addition, to investigate the transport properties of HEP and HEP-PLGA using a Caco-2 cell monolayer, and study the roles of the efflux transporters (P-gp) during the transport process. These results suggested that HEP can be absorbed more efficiently when encapsulated within the PLGA. These findings highlight the potential to the application of HEP in the formulation of functional foods. These results provide strategies in designing high absorbed polysaccharides with bioactive benefits.
