Partitioning of α-lactalbumin and β-lactoglobulin in whey protein concentrate/ hydroxypropylmethylcellulose aqueous two-phase systems
(Elsevier, 2011-05)
Whey protein concentrate (WPC) was fractionated by using hydroxypropylmethylcellulose (HPMC) at pH 6.5. Incompatible mixtures with different proportions of HPMC and WPC were prepared. After phase separation, the protein ...
Hydroxypropylmethylcellulose at the oil-water interface. Part I. Bulk behaviour and dynamic adsorption as affected by pH
(Elsevier, 2011-01)
The bulk and oil-water (O/W) surface behaviour of four different commercial types of hydroxypropylmethylcelluloses (HPMCs) was studied at pH3 and 6.Dynamic light scattering (DLS) analysis of particle size distribution in ...
Hydroxypropylmethylcellulose at the oil-water interface. Part II. Submicron-emulsions as affected by pH
(Elsevier, 2011-07)
The emulsifying behavior of four different commercial types of hydroxypropylmethylcellulose (HPMC) was studied and correlated with the properties of the interfacial films. Emulsions resulted multimodal when made by a high ...
A clinical comparison between DisCoVisc and 2% hydroxypropylmethylcellulose in phacoemulsification: a fellow eye study
(Faculdade de Medicina / USP, 2012)
OBJECTIVE: This study sought to compare the effects and outcomes of two ophthalmic viscosurgical devices, 1.6% hyaluronic acid/4.0% chondroitin sulfate and 2.0% hydroxypropylmethylcellulose, during phacoemulsification. ...
Impact of hydroxypropylmethylcellulose on whey protein concentrate spread film at the air-water interface: Structural and surface dilatational characteristics
(Elsevier Science, 2015-01)
The static (film structure and elasticity) and dynamic features (surface dilatational properties) of whey protein concentrate (WPC) spread films at the air-water interface, as influenced by three commercial hidroxypropyl ...
The impact of HPMC structure in the modulation of in vitro lipolysis: The role of bile salts
(Elsevier, 2017-01)
The behaviour of two hydroxypropylmethylcelluloses (HPMC), with different molecular structures: E5LV and E4M, has been analysed in the presence of the bile salts, both at the oil-water interface (emulsion behaviour, ...
