Development, Characterization, and Stability of O/W Pepper Nanoemulsions Produced by High-Pressure Homogenization

Formation, Characterization and Stability of Nanoemulsions Prepared by Phase Inversion

Formation and stability of n-undecane in water nanoemulsions prepared by EIP method (Emulsion Inversion Point) in the presence of two nonionic surfactants were studied. In the study, the influences of surfactant concentration, HLB value and oil–to–water ratio on the particle size and distribution were investigated. The stability of emulsions was evaluated from changes in particle size distribut...

Effects of Small and Large Molecule Emulsifiers on the Characteristics of b-Carotene Nanoemulsions Prepared by High Pressure Homogenization

Oil-in-water (O/W) nanoemulsion allows the preparation of lipophilic nutrients such as carotenoids in liquid form, which may improve their bioavailability and broaden applications. In the present study, polyoxyethylene sorbitan monolaurate (Tween 20, TW-20), decaglycerol monolaurate (DML), octenyl succinate starch (OSS), whey protein isolate (WPI), and finally a blend of TW-20 and WPI (1 % by m...

Microbial Cell Disruption by High-Pressure Homogenization

Stability and Biological Activity Evaluation of Chlorantraniliprole Solid Nanodispersions Prepared by High Pressure Homogenization

Poorly water-soluble compounds are difficult to develop as pesticide products and face great challenges in water-based and environmentally friendly formulation development. In this study, high pressure homogenization combined with lyophilization was adopted to prepare the solid nanodispersions of chlorantraniliprole with poor solubility and high melting point. The mean particle sizes of the sol...

Isolation and Characterization of Polygalacturonase Produced by Tetracoccosporium sp.

Thirty-five fungal strains which isolated from vegetable wastes, were screened for the use of polygalacturonic acid as the sole carbon source. Twenty-five isolates were positive for polygalacturonase activity in cup-plate assay, as evidenced by clear hydrolysation zones. The most productive strain was determined by measuring clear zones formed around colonies stained with ruthenium red.</em...
