Casein and whey protein were hydrolyzed using 11 different commercially available enzyme preparations. Emulsion-forming ability and emulsion stability of the digests were measured as well as biochemical properties with the objective to study the relations between hydrolysate characteristics and emulsion properties. All whey protein hydrolysates formed emulsions with bimodal droplet size distrib...

The purpose of the present study was to develop the Solutol HS15-based doxorubicin submicron emulsion with good stability and overcoming multi-drug resistance. In this study, we prepared doxorubicin submicron emulsion, and examined the stability after autoclaving, the in vitro cytotoxic activity, the intracellular accumulation and apoptpsis of doxorubicin submicron emulsion in MCF-7/ADR cells. ...

Egg yolk lecithin (EYL) is a good source of phosphatidylcholine (PC) and phosphatidylethanolamine (PE), and it is different from soy lecithin (SL) in both fatty acid and phospholipid class composition. These factors may lead to different behavior in oxidative stability and emulsification properties in food systems. Therefore, these characteristics were investigated in this study. Emulsification...

Gum odina and various parts of the plant Odina wodier are traditionally used in Indian folk medicine. Here an effort was made to investigate the efficacy of gum odina as new pharmaceutical excipients, in particular, as an emulsifying agent. Primary emulsion was prepared using wet gum method taking oil: water: gum (4:2:1) with gum acacia powder as an emulsifying agent. This was used as a standar...

To fabricate a soy protein emulsion with good storage stability against microorganisms, we investigated the stability and antimicrobial activity of a b-conglycinin (7S) and chitosan (CS) mixed emulsion at acidic pHs. Results of droplet size and microstructure showed that 7S/CS mixed emulsions were stable at acidic pHs while the 7S emulsion was not. As for the storage test, results showed that t...

Background: Water in oil (W/O) nanoemulsions can be advantageous for encapsulation of bioactive hydrophilic substance alone or as a structural unit of a double emulsion. Methods: The influence of sonication time, addition of CaCl2 or bovine serum albumin (BSA) to aqueous phase, oil phase (corn or miglyol), and polyglycerol polyricinoleate (PGPR) content on droplet size and physical stability of...

background and objectives : haemorrhagic septicaemia (hs), caused by pasteurella multocida, is the most important bacterial disease of cattle and buffaloes in india. oil adjuvant vaccine (oav) is the most potent vaccine available for the control of hs. the study aims to evaluate the effect of alum co-adjuvantation of oav on emulsion stability and immune response. materials and methods : two dif...

A novel technique for studying the stability of emulsions has been developed. Owing to the fact that emulsion turbidity is a function of particle concentration and size, the stability of emulsions can be determined by measuring the change in turbidity with time. The relationship between turbidity and particle size and concentration is derived for a polydispersed emulsion. The stability of acous...
