The Oil-in-water emulsion emulsifying ability was ﬁrst increased and then decreased with an increase in the PBPH concentrations, and the Emulsifying stability emulsion with 0.75% PBPH displayed the highest emulsifying activity index and emulsion stability index Oxidative stability (p< 0.05). The results obtained for the peroxide values and thiobarbituric acid-reactive substances showed that the addition of PBPH signiﬁcantly increased the inhibition of the lipid oxidation of the emulsion during 14 d of storage. The addition of PBPH signiﬁcantly reduced the zeta-potential and particle size, and the highest zeta- potential and the smallest particle size were found in
