Three peaks, labeled a 0, aj0, a Q, in the real part of a60(x) for a water droplet are shown in Fig. 11.9 the real part of the refractive index is fixed but the imaginary part is varied. These optical constants could be obtained by, for example, adding a little dye (food coloring) to water this would increase k without appreciably changing n. Note that the horizontal scale is different for... 

The U.S. Food and Drug Administration (FDA) regulates the addition of nitrate and nitrite salts to fish products. Maximum permitted levels vary among products and types of fish, with up to 500 ppm residual sodium nitrate or 200 ppm sodium nitrite permitted as a preservative and color fixative in smoke cured sable fish, shad, or salmon (Code of Federal Regulations, 1981a,b Committee on Nittite and Alternative Curing Agents in Food, 1981). 

Generally, food laws state which substances may be used for which foods. Sometimes, the maximum amount permitted in a food and other conditions are also fixed. Both authorization and maximum amount are based on technological necessities, with calculation of a sensible safety margin. In contrast to other food additives, major differences exist in the food-coloring laws of the EU countries, the United States and Japan. 

Cottonseed oil is the refined fixed oil obtained from the seed of cultivated varieties of Gossypium hirsutum Linne or of other species of Gossypium (Fam. Malvaceae). The seeds contain about 15% oil. The testae of the seeds are first separated and the kernels are then exposed to powerful expression in a hydraulic press. The crude oil thus obtained has a bright red or blackish-red color and requires purification before it is suitable for food or pharmaceutical purposes. 

Sand dollars are so flat that at first look they do not resemble their echinoderm relatives. The plates of their skeletons are fused and fixed, and the external surfaces are covered with tiny spines that look like fuzz or a short coat of hair. Sand dollars use their spines to burrow into sand. Once buried, the spines collect small food particles that fall among the spines and transfer them to the mouth. As shown in the upper color insert on page C-7, the common sand dollar (Echinarachnius parma) may be brown with purple or red tints. A five-petal pattern on the sand dollar s dorsal side corresponds to the five legs of a starfish. Holes near the tips of the petals allow the animal to extend tube feet, which are used for respiration. Most specimens measure about 3 inches (7.5 cm) in width. 

Use Nutrition, color fixing, flavoring and preservative in meats and other foods, oxidant in bread doughs, abscission of citrus fruit in harvesting, reducing agent in analytical chemistry. The iron, calcium, and sodium salts are available for biochemical research. 

Products and Uses Used in coffee (decaffeinated), fruits, hops extract, spice oleoresins, vegetables, adhesives, glues, cleaners, waxes, oven cleaners, paint strippers, paint removers, shoe polish, varnishes, stains, and sealants. It is also a degreasing and cleaning fluid used as a solvent for food processing. Used for color dye or fixative and as an extraction solvent. Not used much as a propellant anymore.
