The density of fresh papaya pulp varied between 1.043 and 1.048 , whereas after whipping for 15 min , it decreased to between 0.724 and 0.426 .
The foam density was decreased as the concentration of egg albumin was increased.
Stated that for foam mat drying, the low density foams are stabled for longer time thereby reduced drying time and the optimum range of density of foamed material should be between
