摘要：
Single foam films made from mixtures of nonaggreated proteins and protein aggregates have been studied using a thin film balance apparatus. Their features (heterogeneity, stability and resistance to pressure change) are dependent on the aggregate size and on the ratio between nonaggregated proteins and protein aggregates. A phase diagram of these foam films has been drawn and a correlation of the structural properties of foam film and stability of real foams has been found, In particular, the formation of a gel-like network within the foam film coincides with the stability of the corresponding 3-D foams.
