Surface dilatational behavior of β-casein at the solution/air interface at different pH values

Adsorption of proteins at the solution/air interface influenced by added non-ionic surfactants at very low concentrations for both components. 1. Dodecyl dimethyl phospine oxide

“…The surface tension isotherms of BCS solutions taken from [18,19] and BLG solutions taken from [20] are summarized in Fig. 1.…”

“…1. It should be noted that the experiments in [18,20] were performed by the emerging bubble profile method, and in [19] by the Wilhelmy plate. Fig.…”

“…1. Equilibrium surface tension as a function of protein concentration at pH 7: ( ) BCS as measured by bubble profile tensiometry [18]; ( ) BCS as measured by Wilhelmy plate [19]; (♦) BLG as measured by bubble profile tensiometry [20]; black dashed line -calculated for BLG from the model given in [20]; ( ) and ( ) data of this work for BCS and BLG measured by using the buoyant bubble profile method; black solid and red lines, respectively, were calculated for BLG and BCS from the model given in [21] using the data summarized in Table 1. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)…”

Sugar beet leaves for functional ingredients

“…lipases, glutamate dehydrogenase) (Beverung et al, 1999), -casein (Dan et al, 2014;Wüstneck et al, 2012) and for oleosins (Nikiforidis et al, 2013). In all cases, the equilibrium interfacial tension is reached after  20 h, except for oleosins ( 7 h).…”

The role of casein micelles and their aggregates in foam stabilization

“…Data were obtained using the pendent drop method and SINTERFACE software (Profile Analysis Tensiometer PAT 1-M version 1.4.0.685), according to Wüstneck et al(2012) [18] with some modifications. The area of the droplet was 25 mm 2 .…”
