Abstract

Abstract: Folic acid is susceptible to degradation under acidic conditions; therefore, it needs to be protected during its passage through GI tract. Hence in the present study, the folic acid was encapsulated in horse chestnut starch and β-cyclodextrin by spray drying technique and the release behavior of capsules were investigated during simulated gastric conditions. The structural and thermal properties of capsules were evaluated by SEM, ATR-FTIR, and DSC. The encapsulation efficiency of starch and β-cyclodextrin was found to be 57.29% and 76.10% respectively. A characteristic band at 1800 cm −1 confirmed the presence of folic acid in the microcapsules. The microcapsules showed higher transition and melting temperatures than free folic acid that revealed thermal stability of folic acid upon encapsulation. The higher antioxidant and folic acid content in intestinal juice than gastric juice ensured controlled release in the intestine. Graphical abstract: Highlights: Folic acid was encapsulated in horse chestnut starch and β- cyclodextrin. Particle size distribution, thermal stability and structural analysis were carried out. Release of folic acid and antioxidant potential of microcapsules were studied under GI tract conditions. Folic acid was better retained in the microcapsules that ensure its sustainable release in intestinal conditions.
