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...

Microcapsules containing the aqueous solution of Azur B of a water soluble dye were prepared with the melting dispersion cooling method and applied to the amplification detector of plant DNA. Paraffin wax with melting temperature of 75 ̊C was used as the shell material. In the experiment, the aqueous solution (W) of Azur B as the core material was dispersed in the melted paraffin wax (O) to form...

Perfluorocarbon (PFC) double emulsions loaded with a water-soluble, therapeutic agent can be triggered by ultrasound in a process known as acoustic droplet vaporization. Elucidating the stability and biodistribution of these sonosensitive vehicles and encapsulated agents is critical in developing targeted drug delivery strategies using ultrasound. [(18) F]fluorodeoxyglucose (FDG) was encapsulat...

STUDY OBJECTIVES Lipid emulsions have been suspected of inducing certain modifications in gas exchange and pulmonary hemodynamics. The aim of this prospective study was to evaluate the hemodynamic and pulmonary effects of two lipid emulsions. DESIGN Prospective, randomized, double-blind, crossover study. SETTING Medical and surgical ICU in a French university hospital. PATIENTS Eighteen p...

Investigations were carried out on development quality evaluation and shelf life studies of buffalo meat emulsion sausage prepared by different levels of fat and skimmed milk powder (SMP) at refrigerated storage temperature (0°C). The quality of emulsion sausage was based on the basis of physico-chemical characteristics namely moisture content, pH, protein content, TBA number, microbial charact...

The utilization of carboxylic ionophores such as monensin for immunotoxin potentiation may be hampered by the poor solubility and short in vivo half-life of these highly lipophilic compounds. Therefore, the use of monensin formulated in a lipid/water emulsion was investigated for the in vitro and in vivo potentiation of immunotoxins. Monensin in emulsion or in buffer was equally effective for t...

The antioxidant activity of pectic enzyme treated pectin (PET-pectin) prepared from citrus pectin by enzymatic hydrolysis and its potential use as a stabilizer and an antioxidant for soy protein isolate (SPI)-stabilized oil in water (O/W) emulsion were investigated. Trolox equivalent antioxidant capacity (TEAC) was found to be positively associated with molecular weight (M(w)) of PET-pectin and...

The aim of this study was to determine the kinetic parameters of the oxy-fuel combustion of char from a Brazilian bituminous coal with a high ash content. The char, with a particle diameter of 715 μm, was prepared in a N2 atmosphere at 1173 K. The oxy-fuel combustion assays were performed using a thermobalance at different temperatures and O2/CO2 gas mixtures of different concentrations. Accord...

The effects of the initial emulsion structure (droplet size and emulsifier) on the properties of β-carotene-loaded emulsions and the bioavailability of β-carotene after passing through simulated gastrointestinal tract (GIT) digestion were investigated. Exposure to GIT significantly changed the droplet size, surface charge and composition of all emulsions, and these changes were dependent on the...

The Emulsion is a hydraulic support's transmission medium and its concentration directly affects the working life and cost of the hydraulic support and the pillar,so strict testing for emulsion concentration is necessary. Aiming to the common methods of the emulsion concentration detection and development current situation of the fiber grating refractive index sensing technology at home and abr...
