animal jelly,

foodstuff obtained from connective tissue (found in hoofs, bones, tendons, ligaments, and cartilage) of vertebrate animals by the action of boiling water or dilute acid. It is largely composed of denatured collagencollagen
, any of a group of proteins found in skin, ligaments, tendons, bone and cartilage, and other connective tissue. Cells called fibroblasts form the various fibers in connective tissue in the body.

, a protein particularly rich in the amino acids proline and hydroxyproline. The process of manufacture is a complex one that involves removing foreign substances, boiling the material (usually in distilled water in aluminum vessels to prevent contamination), and purifying it of all chemicals used in freeing the gelatin from the connective tissues. The final product in its purest form is brittle, transparent, colorless, tasteless, and odorless and has the distinguishing property of dissolving in hot water and congealing when cold. In contact with cold water it takes up from 5 to 10 times its own weight and swells to an elastic, transparent mass. Gelatin, being readily digested and absorbed, is a good food for children and invalids. It is important in fine cookery as a vehicle for other materials, in the form of jellied soups, molded meats and salads, and frozen desserts. Preparations of it are used in the home manufacture of jam, jellies, and preserves to ensure jellification of fruit juices. It is used in the drying and preserving of fruits and meats, in the glazing of coffee, and in the preparation of powdered milk and other powdered foods. Bakeries use it in making meringues, eclairs, and other delicacies. In confectionery making it is used as the basis of taffy, nougat, marshmallows, and fondant. Ice cream manufacture employs it to maintain a permanent emulsion of other ingredients and thus to give body to the finished product. In scientific processes gelatin is widely employed, being used in electrotyping, photography, waterproofing, and dyeing, and in coating microscopic slides. It is used as a culture medium for bacteriological research and also to make coatings for pills and capsules, for court plaster, and for some surgical dressings. It affords a base for ointments and pastes, such as toothpaste; it is an emulsifying agent useful in making liquid combinations and various sprays. In its less pure forms gelatin is known as glue and size. Vegetable gelatin, or agaragar
, product obtained from several species of red algae, or seaweed, chiefly from the Ceylon, or Jaffna, moss (Gracilaria lichenoides) and species of Gelidium, harvested in eastern Asia and California.

(gelatine), a mixture of protein substances of animal origin.

Gelatin is prepared from bones, tendons, and cartilage by prolonged boiling in water. In this process collagen, a component of connective tissue, becomes gluten. The resulting solution is evaporated, clarified, and chilled until it is converted to a gel, which is cut in pieces and dried. Gelatin is produced in sheet or powdered form. Finished dry gelatin is tasteless, odorless, transparent, and almost colorless or slightly yellow. It swells greatly in cold water and dilute acids, but does not dissolve. Upon heating, the swollen gelatin dissolves, forming a sticky solution that hardens to a gel. It is used in medicine and biology (as styptic or nutrient media), in pharmacy (the manufacture of capsules, suppositories, and so forth), in the food industry (production of gelatin, jelly, marmalade, and other confectionery products), in photography and cinematography (preparation of emulsions in the light-sensitive layer of cinema film, photographic paper, and X-ray film), and in industry (the sizing of high-grade paper; the manufacture of paper money, paints, artificial pearls, and other goods).

The preparation process of gelatin gels is as follows: (1) the mixed 10 g gelatin sample was placed in a 250 mL beaker and added with 100 mL purified water to soak for about half an hour; (2) the beaker was placed in a water bath pan for heating by setting the temperature at 50[degrees]C, and the solution was stirred while heating until the gelatin was completely dissolved; (3) after cooling to room temperature, the gelatin solution was poured into a small square mold and then placed in a refrigerator to cool about 5 hours for shaping.
