    • n Gelatin (Chem) Animal jelly; glutinous material obtained from animal tissues by prolonged boiling. Specifically Physiol. Chem, a nitrogeneous colloid, not existing as such in the animal body, but formed by the hydrating action of boiling water on the collagen of various kinds of connective tissue (as tendons, bones, ligaments, etc.). Its distinguishing character is that of dissolving in hot water, and forming a jelly on cooling. It is an important ingredient of calf's-foot jelly, isinglass, glue, etc. It is used as food, but its nutritious qualities are of a low order.☞ Both spellings, gelatin and gelatine, are in good use, but the tendency of writers on physiological chemistry favors the form in -in, as in the United States Dispensatory, the United States Pharmacopœia, Fownes' Watts' Chemistry, Brande & Cox's Dictionary.

  • Interesting fact: Many wonder what the difference is between jelly, preserves, jam, and marmalade. In all cases, jelly is the common denominator. Jelly is fruit juice with added sugar, cooled and congealed, usually by the addition of gelatin or pectin. Preserves preserve the largest percentage of the original fruit, containing whole chunks of it in addition to jelly. Jam is jelly plus fruit pulp. Marmalade has bits of fruit and the rinds in a jelly. Although the orange variety is most common, it is often made from other citrus fruits. Spread either of the four on toast, add a nice cup of tea, and you have one sweet treat.
    • n gelatin A concrete animal substance, transparent, hard, and tasteless, which swells without solution in cold water, dissolves in warm water and in acetic acid, and is insoluble in alcohol or ether. Gelatin does not exist as such in the animal tissues, but is formed by the action of boiling water on connective tissues, cartilage, ligaments, and tendons, as well as on skin, horn, fish-scales, etc. The coarser form of gelatin from hoofs, hides, etc., is called glue; that from skin and finer membranes is called size; and the purest gelatin, from the air-bladders and other membranes of fish, is called isinglass. Its leading character is the formation of a tremulous jelly when its solution in boiling water cools. A yellowish-white precipitate is thrown down from a solution of gelatin by tannin, which forms an elastic adhesive mass. Tannin has the same action also on the tissues from which gelatin is made, and this action of tannin is the foundation of the art of tanning leather. Gelatin is nearly related to the proteids. It is regarded as a nutritious food, and much used in preparing soups, jellies, etc.; but animals fed exclusively on it die with the symptoms of starvation. No chemical formula has yet been deduced for gelatin. It contains about 18.3 per cent, of nitrogen, 0.6 per cent, of sulphur, 50 of carbon, 7 of hydrogen, and 23 of oxygen. (See jelly.) In all the arts allied to photography, gelatin forms the basis of a great variety of processes. It is at present the usual vehicle for holding the sensitive salts of silver in dry plates, and for holding the sensitive bichromate of potash in all the photo-printing and photo-engraving processes. (See emulsion, carbon process (under carbon), photolithography, heliotype, and photography.) Gelatin is also used to form the copying-pad in a variety of copying processes. See hectograph.
