摘要： Mangiferin (MGF) is a phenolic compound isolated from mango, but its poor solubility significantly limits its use. In this study, MGF was embedded into the inner aqueous phase of W-1/O/W-2 emulsions. Firstly, the dissolution method of MGF was determined. MGF remained stable in solution with pH 13 at 30 min, and its solubility reached 10 mg mL(-1). When the pH of MGF solutions was adjusted from pH 13 to pH 6, MGF did not immediately crystallise, providing sufficient time to construct the MGF-loaded W-1/O/W-2 emulsions. Subsequently, the MGF-loaded W-1/O/W-2 emulsions were constructed using polyglycerol polyricinoleate (PGPR) and calcium caseinate (CAS). The formation and stability of the W-1/O/W-2 emulsions were investigated. The MGF-loaded W-1/O/W-2 emulsions stabilised with 1% PGPR and 1% - 3% CAS exhibited a low viscosity, limited loading capacity, and poor stability. Conversely, the MGF-loaded W-1/O/W-2 emulsions stabilised by 3%PGPR-3%CAS exhibited optimal loading capacity (encapsulation efficiency = 95.31% and loading efficiency = 0.91%) and stability, which was attributed to the fact that high viscosity and gel state retarded the migration of inner aqueous phase. These results indicated that the W-1/O/W-2 emulsions stabilised by PGPR and CAS may be a potential alternative for encapsulating mangiferin.
