In this study, the effect of the interaction between WPC and OSAS in aqueous solution (at total biopolymer concentration 1% w/w) as function of pH (3, 4, 5, 6) and ratio (1:2, 1:1 and 2:1) on the foaming properties (bubble size, foaming capacity and foam stability) was investigated. Smaller bubbles size showed more foam stability. Lowest bubbles size was observed at 1:1 and pH 4 (226.52 µm) and statistical difference between pure WPC (396.15 µm) and WPC-OSAS complex solutions at this pH was significant. Maximum foaming capacity was observed at ratio 1:1 and pH 3 (%186.33) and maximum foam stability was calculated at 1:2 WPC: OSAS and pH 4 (%83.27) and there was significant statistical difference with control sample (WPC solution) (%50.74). This research showed that electrostatic interaction between WPC and OSAS can be used as an effective method for improving foaming capacity and foam stability of WPC at low concentrations.
