Effect of Sodium Sulfite, Sodium Dodecyl Sulfate, and Urea on the Molecular Interactions and Properties of Whey Protein Isolate-Based Films
Whey protein coatings and cast films are promising for use as food packaging materials. Ongoing research is endeavoring to reduce their permeability. The intention of this study was to evaluate the effect of the reactive additives sodium sulfite, sodium dodecyl sulfate (SDS), and urea on the oxygen barrier, water vapor barrier, and protein solubility of whey protein cast films. The concentratio...
متن کاملSoy Protein Isolate/Poly(ethylene oxide) Films
Cereal Chem. 72(6):559-563 Films were prepared by casting and drying alkaline aqueous filmelongation at break (E). TS values ranged from 1.4 to 3.9 MPa and E forming solutions of soy protein isolate (SPI). Four additional types of values ranged from 83 to 152%. Water vapor permeability of the films films were made by combining SPI with poly(ethy1ene oxide) (PEO) in ranged from 3.0 x to 4.0 x gl...
متن کاملProperties of Cast Films Made from Different Ratios of Whey Protein Isolate, Hydrolysed Whey Protein Isolate and Glycerol
Whey protein isolate (WPI)-based cast films are very brittle, due to several chain interactions caused by a large amount of different functional groups. In order to overcome film brittleness, plasticizers, like glycerol, are commonly used. As a result of adding plasticizers, the free volume between the polymer chains increases, leading to higher permeability values. The objective of this study ...
متن کاملFoaming properties of soy protein isolate hydrolysates
Tensoactive species obtained by papain hydrolysis of soy protein were characterized structurally and physicochemically, and their foam-forming and -stabilizing capacity studied. Protein structural changes upon reaction ending were correlated with functional and interfacial properties and with the behaviour thereof with varying hydrolysis degree. Two different means of halting hydrolysis -pH red...
متن کاملThe gross conformation of protein-sodium dodecyl sulfate complexes.
The interaction of sodium dodecyl sulfate with a wide variety of proteins is characterized by a high binding ratio when the monomer concentration of amphiphile exceeds 5 x 10W4 M. This binding ratio on a gram to gram basis is identical for all proteins investigated. The protein portion of the complex contains a high degree of order, and hydrodynamic studies suggest that the complex is a rodlike...
