Foam-mat drying of papaya pulp using egg albumin as foaming agent was investigated.
The egg albumin was incorporated into papaya pulp at 5, 10, 15 and 20% (w/w) and
whipped for 5, 10, 15 and 20 min in room temperature. Foam expansion, foam stability
and foam density were determined. The maximum stable foam formation was
125.62% at 15% egg albumin and whipping time of 15 min.
