• Film-forming solutions were prepared
• The whey protein isolate was dissolved in distilled water at 8% (w/w) under 250 rpm constant magnetic stirring and heat on magnetic plate at 80 ◦C for 30 minutes to denature the whey protein , then the solutions were cooled down to room temperature and glycerol 50% (w/w) was added as a plasticizer.
• Add almond and walnut oil at 0.5 and 1.0% were homogenized with whey protein isolate solution at 13,500rpm with Ultra Turrax for 5 to minutes to produce emulsions
