Effect of native potato starch maltodextrins on stability and rheological properties of albumin foams

The aim of this work was to evaluate the effect of dextrose equivalent and concentration of potato maltodextrins on stability and rheological properties of egg albumin foams. It was found that maltodextrins can act as stabilising agents for aerated food systems. This characteristic of maltodextrin depends on its DE value and concentration. The foams containing 20 and 30 wt% of maltodextrin of DE 6 did not undergo destabilisation in time, contrary to the foams with maltodextrins of DE 11 and DE 16. All the foams showed viscoelastic properties with a domination of the elastic ones and they exhibited characteristics typical of a weak gel. The foams with maltodextrins were less susceptible to deformation as compared to the foam without maltodextrin. The susceptibility to deformation of the foams decreased with a decrease in the maltodextrin DE value and with an increase in the maltodextrin concentration.
