orphan date August 2009 Meat emulsion is a two phase system, with the dispersed phase consisting of either solid or liquid fat particles and the continuous phase being the water containing salts and dissolved, gelled and suspended proteins . Thus they can be classified as oil in water emulsion. Meat emulsion is not a true emulsion since the two phases involved are not liquids and the fat droplets in a commercial emulsion are larger than 50 m in diameter and thus do not conform to one of the requirement of a classical emulsion. The continuous phase mainly consists of water, water soluble proteins and salt soluble proteins. The dispersed phase or discontinuous phase consists of fat droplets. The water soluble proteins are sarcoplasm sarcoplasmic proteins such as Myoglobulin and other pigments , salt soluble proteins are Myofibrillar proteins such as mysoin, actin , actinin , alpha actinin, beta actinin. Meat Emulsifiers When used in food products, iota carrageenan and Sodium stearoyl lactylate SSL have a synergistic effect allowing for stabilizing emulsifying that is not obtained with any other type of carrageenan kappa lambda or with other emulsifiers Monoglyceride , etc. . Sodium stearoyl lactylate combined with iota carrageenan is capable of producing emulsions under both hot and cold conditions using either vegetable or animal fat.

In a Particle Physics Particle and Nuclear physics , a nuclear emulsion plate is a photographic plate with a particularly thick emulsion layer and with a very uniform grain size. Nuclear emulsion is a systematic study of absorption of pion in a complex nucleus of a high energy particle. Nuclear emulsions can be used to record and investigate fast charged particles like nucleon s or meson s. After exposing and developing the plate, single particle tracks can be observed and measured using a microscope. In 1966, Ishfaq Ahmad made further advances in the field, and proposed the inelastic collision of Beta particle between the heavy nuclei and the Interference wave propagation light wave interference , using the particle detectors at CERN, can results in heavy absorption of multiple pion in a complex energy particle. In 1937 , Marietta Blau and Hertha Wambacher discovered nuclear disintegration stars due to spallation in nuclear emulsions that had been exposed to cosmic radiation at a height of 2300 m 7500 feet above sea level. Using nuclear emulsions exposed on high mountains, Cecil Frank Powell and coworkers discovered the pion in 1947. References J.

A Pickering emulsion is an emulsion that is stabilized by solid particles for example colloidal silica which adsorb onto the interface chemistry interface between the two phase matter phase s. This type of emulsion was named after Percival Spencer Umfreville Pickering S.U. Pickering , who described the phenomenon in 1907, although the effect was first recognized by Walter Ramsden in 1903. ref cite web url http dx.doi.org 10.1039 CT9079102001 title Emulsions S.U.

Soc. London 72 1903 156 ref If oil and water are mixed and small oil droplets are formed and dispersed throughout the water, eventually the droplets will coalesce to decrease the amount of energy in the system. However, if solid particles are added to the mixture, they will bind to the surface of the interface and prevent the droplets from coalescing thus causing the emulsion to be more stable. Properties such as hydrophobicity , shape, and size of the particle can have an effect on the stability of the emulsion. The particle s contact angle to the surface of the droplet is a characteristic of the hydrophobicity. If the contact angle of the particle to the interface is low, the particle will be mostly wetted by the droplet and therefore will not be likely to prevent coalescence of the droplets. Particles that are partially hydrophobic i.e. contact angle of approximately 90 are better stabilizers because they are partially wettable by both liquids and therefore bind better to the surface of the droplets.

Creaming , in the laboratory sense, is the migration chemistry migration of the dispersed phase of an emulsion , under the influence of buoyancy . The particles float upwards or sink, depending on how large they are and how much less dense or more dense they may be than the continuous phase, and also how viscous or how thixotropic the continuous phase might be. For as long as the particles remain separated, the process is called creaming. Where it is important that either the form or the concentration of the emulsion should be stable, it is desirable that the continuous and the dispersed phases should have similar densities, and it also is desirable that the continuous phase should be viscous ... to concentrate an emulsion.

Unreferenced stub auto yes date December 2009 Duplitized film stock was a type of film available through various companies used in color photography and special effects . It was introduced in the early 1910s. The stock was of standard gauge and thickness, but carried an emulsion on each side of the base. For color film processes such as Cinecolor or Prizma , red and blue or red and green negatives would be exposed, one to each emulsion. Yellow dye in the emulsion would slow the exposure light from the negative down from exposing both sides. When processed to black and white, the dye was washed out, and the respective images were converted from black and white to color by means of Film tinting toning both emulsions their appropriate color.

refimprove date July 2009 An anti halation backing is a layer found in most photographic film s. It is usually a coating on the back of the film base , but sometimes it is incorporated between the light sensitive photographic emulsion emulsion and the base. The light that passes through the emulsion is absorbed by the anti halation layer. This prevents any light from being reflected back through the emulsion from the rear surface of the base, or from anything behind the film, and causing a halo like effect around bright points or edges in the image. The anti halation layer is rendered transparent or washed out as in K 14 process K 14 films during photographic processing processing of the film. The lack of an anti halation layer in Kodak s High Speed Infrared photography Black and white infrared film Infrared film HIE is the cause of the ethereal glowing effect often associated with infrared photography ref name photonotes http photonotes.org cgi bin photo entry.pl?id Antihalationlayer ref , rather than an artifact of IR itself.

Unreferenced stub auto yes date December 2009 Context date October 2009 The Bancroft rule states The phase matter phase in which an emulsifier is more soluble constitutes the continuous phase. It was named after Wilder Dwight Bancroft , an American physical chemist. In all of the typical emulsion s, there are tiny particles discrete phase suspended in a liquid continuous phase . In an oil in water emulsion, oil is the discrete phase, while water is the continuous phase. What the Bancroft rule states is that contrary to common sense, what makes an emulsion oil in water or water in oil is not the relative percentages of oil or water, but which phase the emulsifier is more soluble in. So even though there may be a formula that s 60 oil and 40 water, if the emulsifier chosen is more soluble in water, it will create an oil in water system. There are some exceptions to Bancroft s rule, but it s a very useful rule of thumb for most systems. The Hydrophilic lipophilic balance or HLB of a surfactant can be used in order to determine whether it s a good choice for the desired emulsion or not. In Oil in Water emulsions use emulsifying agents that are more soluble in water than in oil High HLB surfactants . In Water in Oil emulsions use emulsifying agents that are more soluble in oil than in water Low HLB surfactants . Bancroft s rule suggests that the type of emulsion is dictated by the emulsifier and that the emulsifier should be soluble in the continuous phase. This empirical observation can be rationalised by considering the interfacial tension at the oil surfactant and water surfactant interfaces.

Intralipid is a brand name for the first safe fat emulsion for human use, approved in 1962 in Europe and invented by Professor Arvid Wretlind, Sweden. The FDA initially would not approve the product due to prior experience with another fat emulsion. It was approved in the United States in 1972. It is used as a component of parenteral nutrition for patients who are unable to get nutrition via an oral diet. It is an emulsion of soy bean oil, egg phospholipids and glycerin. It is available in a 10 , 20 and 30 concentration. The 30 concentration is not approved for direct intravenous infusion, but should be mixed with amino acids and dextrose as part of a total nutrient admixture. Intralipid provides essential fatty acids, linoleic acid LA , an omega 6 fatty acid, alpha linolenic acid ALA , an omega 3 fatty acid . Some preparations of the anaesthetic drugs propofol and etomidate the vehicle for etomidate is propylene glycol are supplied using Intralipid as a vehicle.
