June 23/Zarqa, Jordan/Food Business Week -- According to recent research from Zarqa, Jordan, "Comparisons of the physical and sensory properties of several commercial egg alternatives in angel food cake formulation were studied. Fourteen samples were investigated for foaming properties at 10 and 20 minutes whipping time: collagen, Cryogel gelatin, Solugel collagen hydroysates, gelatin, whey protein concentrate, fish protein, whey protein isolate (95% WPI, 90% WPI), hydrolyzed whey protein isolate, pea protein, rice protein concentrate, soy protein, corn zein and casein."
"However, only eight samples showed potential and were moved forward for further evaluation. Only the WPI alternative was able to maintain a meringue during baking. All other foams collapsed during the baking process. The angel food cake formulated with WPI exhibited a significantly firmer crust and crumb compared with the egg white control. The L value, height and volume of control cake were also significantly higher than the egg alternative," wrote M. Abughoush and colleagues, Hashemite University.
