The embedding technology of active ingredients needs to be explored due to the instability of active ingredients extracted from water lily. In this study, Nymphaea 'Blue Bird', a tropical water lily, is used as a target for the extraction of anthocyanin and its embedding in W/O pickering emulsions. W/O emulsions with different volume fractions of the aqueous phase were prepared, using the anthocyanin solution as the aqueous phase (W), soybean oil as the oil phase (O) and the emulsifier selected as the lipophilic emulsifier polyglyceryl ricinoleate (PGPR). The results showed that the W/O emulsions prepared at 30% and 50% of the aqueous phase volume fraction were stable after 15 d of storage at different temperatures, and the encapsulation efficiency of the anthocyanin was 75.97% and 78.12%, respectively, and the encapsulation stability within 15 d was good. The stability of W/O emulsions was investigated by preparing W/O emulsions at different shear rates. The apparent stability of W/O emulsions was achieved when the shear rate was 28 000 r/min, and the retention rate of centrifugation reached 97.40% after 120 min storage. In conclusion, the W/O pickering emulsion prepared in this manuscript was balanced and had a good encapsulation effect on anthocyanins.
