    Soups, Sauces and Emulsions In my lab today I got to make some soup, biscuits, sauce, vanilla pudding, mayonnaise as well as oil and vinegar salad dressing. Emulsion is a process where a liquid is dispersed in another liquid with which it is usually immiscible. There are two types of emulsions. Oil-in-water (oil droplets are dispersed throughout the water) and water-in-oil (water droplets are dispersed throughout the oil). These emulsions can be permanent emulsion or temporary emulsion. In my lab we

    1823 Words  | 8 Pages

    INTRODUCTION Emulsifying agents are substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion. Foods that consist of such emulsion include butter, margarine, salad dressings, mayonnaise, and ice cream. Emulsifying agents are also used in baking to add the smooth incorporation of fat into the dough and to keep the crump soft. Emulsifying agents used in foods include agar, albumin, alginates, casein, egg yolk, glycerol monostearate, gums

  • Essay On Screen Printing

    1737 Words  | 7 Pages

    What's Screen Printing? screen printing (or Silk-screening) is a printing approach that makes use of a woven mesh to guide an ink-blocking off the stencil. The attached stencil bureaucracy open regions of mesh that transfer ink or different printable substances, which may be pressed via the mesh as a sharp-edged photo onto a substrate. A curler or squeegee is moved across the display stencil, forcing or pumping ink beyond the threads of the woven mesh in the open regions. screen printing is likewise

    mice showed that a targeted tissue accumulation and longer residence time were found in triptolide-loaded lipid emulsion [62]. The AUC0-t of triptolide-loaded lipid emulsion increased 2.19 folds, suggesting that the triptolide-loaded lipid emulsion does improve the biodistribution, accumulation and therapeutic efficacy in pancreas. Moreover, the levels of triptolide-loaded lipid emulsion in heart, lung and kidney were lower than that of the triptolide group, which would reduce the toxicity of triptolide

  • The Pros And Cons Of Chip Sealing

    The chip seal is constructed by spraying the asphalt emulsion onto the asphalt roadways, then diffusion chips of clan into the emulsion, embedding the chips with air-driven and rubber tired rollers, and ultimately sweeping to recapture the excess chips. Infrequently, the methods is repeated—a double seal, with emulsion sprinkle again and a second layer of chips added. The methods seals fine rift in the fundamental pavement surface, minimizing

    495 Words  | 2 Pages

    Tempera is a water-thinned paint that becomes water resistant as it dries. . “Egg tempera is an aqueous emulsion paint with an egg yolk or whole egg binder that originated in medieval Europe. These paints dry to a semi-matte appearance by the evaporation of water and the coagulation of the egg protein. After about 1400 CE, variations of tempera were made with egg/oil, gum/oil, glue/oil and other emulsions as artists began to experiment with drying oils. As linseed oil paints became popular at the end of

    This experiment aims to identify the pigments in spinach using column chromatography. The two categories of pigments which exist in spinach are carotenoids and chlorophylls. β-Carotene is non-polar and is a series of repeated isoprene units, see Figure 1 for structure. It varies from α-Carotene by the double bond on the left carbon ring which is shifted over to the left by one set of carbons in α. The chlorophylls are also similar; however, β has a higher polarity than α. Their structures are

    mass. Background A colloid is defined as a solution containing particles that are sized between 1-1000 nanometers and are dispersed throughout the entire solution, never settling to the bottom (Law, 2017). Milk is a type of colloid called an emulsion that contains fat globules and casein proteins (one of the main milk proteins), suspended in a watery surrounding (University of Guelph, 2017). The water is the solution part of this colloid. It contains
