Stearic acid was incorporated into whey protein through emulsification to produce films. Whey protein films were prepared by dispersing 6.5% protein in distilled water. Glycerol was the plasticizer agent. Stearic acid was added at different levels (0.0 to 1.0%) and the films were analyzed at different pHs (5.0, 6.0, 7.0 and 9.0). The emulsion films were evaluated for mechanical properties, wate...

       Food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. Plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. Presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they ...

The possibility of a three-dimensional visualisation/reconstruction of tracks in nuclear emulsion films using X-ray imaging is described in this paper. The feasibility of the technique is established with experimental results.

In the preceding paper it was shown that a phospholipase prepared,from Penicllium notatum will hydrolyse lecithin only after the, addition,, of a minimum proportion of anionic amphipathic molecules1 e.g. dicetylphosphoric acid, cardiolipin, sodium dodecyl sulphate (Bangham & Dawson, 1959), The onset of hydrolysis occurred, only when the emulsion particles carried a minimum net negative charge, ...

In a recent Letter [N. D. Denkov, Phys. Rev. Lett. 100, 138301 (2008)] we calculated theoretically the macroscopic viscous stress of steadily sheared foam or emulsion from the energy dissipated inside the transient planar films, formed between neighboring bubbles or drops in the shear flow. The model predicts that the viscous stress in these systems should be proportional to Ca 1/2, where Ca is...

The use of nuclear emulsions to record tracks of charged particles with an accuracy of better than 1 micron is possible in large physics experiments thanks to the recent improvements in the industrial production of emulsions and to the development of fast automated microscopes. The European Scanning System (ESS) is a fast automatic system developed for the mass scanning of the emulsions of the ...

Crystallization phenomena of organic soft materials occurring in template-controlling systems such as emulsions, vesicles, micelles and air-water interfaces have been discussed by reviewing recent work. Long-chain molecular crystals and amino acids were chosen as the model substances of the organic soft materials which are key materials in food, pharmaceutical, nuetraceutical, cosmetic, and oth...

Polymer-modified bitumen emulsions present a safer and more environmentally friendly binder for enhancing the properties of roads. Cationic bitumen emulsion binders containing polymer latex were investigated using confocal laser scanning microscopy. The latex was incorporated into the bitumen emulsion by using four different addition methods and all emulsions were processed with a conventional ...
