Total phenol, flavonoid and saponin content of soy bean mung were systemically compared in order to evaluate their contribution overall antioxidant activity. Mung extract possessed significantly higher total phenol (2.03 GAE g−1 vs. 1.13 g−1) contents (1.49 0.41 CAE than extract, while the beans was 4.5 times greater that beans. In several assays including DPPH ABTS radical scavenging, FRAP, SOD-like activity, a β-carotene bleaching assay, consistently showed activity extract. The specific...

The interaction between dairy proteins [micellar casein (MC) vs. whey protein isolate (WPI)] and phospholipids [PL; soy phosphatidylcholine (PC) milk sphingomyelin (SM)] in an oil-in-water emulsion system was investigated. Sole PC-stabilized (1%, wt/vol) showed a significantly larger mean particle diameter (6.5 μm) than SM-stabilized emulsions (3.8 μm). diameters of prepared by the combination PL did not differ from with single emulsifier (MC, WPI, SM). Emulsion instability differed among...

Chrysin-loaded phytosomes (CP) were prepared using either soya phosphatidylcholine (SPC) or egg phospholipid (EPL) by the solvent evaporation method. Different matrices resulted in significant differences size, mechanical property and solubility of CP. The most stable CP was obtained with EPL at a molar ratio 1:3 (chrysin: EPL, CEP-1:3). CEP-1:3 displayed an average size 117 nm uniform distribution (polydispersity index: 0.30) zeta potential -31 mV. A significantly greater elastic modulus...

ABSTRACT: Transglutaminase (TGase)‐treated skim milk powder (TG‐SMP) was prepared by freeze‐drying after TGase treatment (10 U/g protein, 40°C for 3 h), followed inactivation at 85°C 5 min. modification resulted in significant increases hardness and water holding capacity (WHC) of heat‐induced gels (10% w/v). A marked increase storage modulus (G′) TG‐SMP upon heating suggests that has a greater gelling ability than control‐SMP (C‐SMP) with predenatured TGase. Acid from had significantly...
