A rheological characterisation of mashed potatoes enriched with soy protein isolate

Development of nanoemulsion-based antimicrobial activity of cinnamon prepared with soy protein isolate-lecithin

The objective of the present research was to develop cinnamon oil nanoemulsions using soy protein isolate and lecithin as food grade natural emulsifiers. For this purpose, stable cinnamon oil nanoemulsion (droplet diameter of 141.2 nm) prepared by ultrasonic emulsification. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of free and nanoemulsified cin...

Rheological Properties of a Soy Protein Isolate and Concentrate: Effect of Gel Strength

The concentration dependence of dynamic moduli G’ and G” of soy protein isolates (SPI) and soy protein concentrates (SPC) were studied in solutions prepared under different conditions. Three-level preliminary fractional experiments were undertaken to study effects of temperature, pH, concentration on the gel strength of soy protein isolate and soy protein concentrate solutions. Protein concentr...

Foaming 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...

Soy 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...
