Abstract

Whey proteins are known as valuable components in both food technology and in non-food production. Whey protein concentrate (WPC 80) wad added during the preparation of waterinoil emulsion (w/o) in the amount of 0, 10 and 15% (w/w). Prepared emulsions were stored for 10 weeks at 20°C ±1°C. Increased concentration of WPC 80 resulted in decreased viscosity of the emulsion. The emulsion with 10% of WPC 80 additive was stable during the whole storage period and exhibited the viscosity value of 1.78 Pa*s. On the contrary, emulsion without WPC 80 and that with its 15% concentration shown slight destabilization symptoms.
