![]() The animal parts are passed under high-pressure water sprays to wash away debris. Then, the bones, tissues, and skins are loaded into chopping machines that cut the parts into small pieces of about Sin (12.7cm) in diameter. When the animal parts arrive at the food processing plant, they are inspected for quality. The Manufacturing Process Inspection and cutting These can be in liquid or powdered forms and are purchased from outside vendors. Sweeteners, flavorings, and colorings are added in the preparation of food gelatin. They are either produced in the food processing plant or purchased from outside vendors. Gelatin processing plants are usually located nearby so that these animal byproducts can be quickly processed.Īcids and alkalines such as caustic lime or sodium carbonate are used to extract minerals and bacteria from the animal parts. Raw MaterialsĪnimal bones, skins, and tissue are obtained from slaughterhouses. Gelatin’s use in the manufacture of medicinal capsules occurred in the twentieth century. It was used to coat dry photographic plates, marking the beginning of modern photographic methods. In the field of photography, gelatin was introduced in the late 1870s as a substitute for wet collodion. ![]() Over a million packages are purchased or eaten each day. Today, 400 million packages of Jello-O are produced each year. The use of gelatin in food preparation increased six-fold in the 40-year period from 1936-1976. Sales continued to limp along until 1902 when an aggressive advertising campaign in Ladies Home Journal magazine generated enormous interest. The new product was not immediately popular and Wait sold the rights to the process to Orator Francis Woodward, owner of the Genesee Food Company, for $450. His wife, May Davis Wait, named his product Jell-O. Wait, a carpenter and cough medicine manufacturer, developed a fruit-flavored gelatin. He had also made a fortune in the manufacture of glue, a process similar to that for making gelatin. ![]() Cooper had already made a name for himself as the inventor of the Tom Thumb steam engine. The first patent for a gelatin dessert was issued in 1845 to industrialist and inventor Peter Cooper. In 1896, Rose Knox published Dainty Desserts, a book of recipes using Knox gelatin. Knox packaged dried sheets of gelatin and then hired salesmen to travel door-to-door to show women how to add liquid to the sheets and use it to make aspics, molds, and desserts. Knox, a salesman from Johnston, New York, who hit on the idea of making gelatin more convenient after watching his wife Rose make it in their kitchen. Sweeteners and or flavorings were added to the liquid and it was poured into molds and allowed again to set.īy the 1840s, however, some producers were grinding the set gelatin into a fine powder or cutting it into sheets.

Calves’ feet were loaded into a large kettle that was then placed over a fire. Until the mid-nineteenth century, making gelatin was a laborious task. Gelatin’s industrial applications include medicine capsules, photographic plate coatings, and dying and tanning supplies. It is also used to clarify beer and wine. Gelatin’s ability to form strong, transparent gels and flexible films that are easily digested, soluble in hot water, and capable of forming a positive binding action have made it a valuable commodity in food processing, pharmaceuticals, photography, and paper production.Īs a foodstuff, gelatin is the basis for jellied desserts used in the preservation of fruit and meat, and to make powdered milk, merinque, taffy, marshmallow, and fondant. ![]() It is produced by boiling the connective tissues, bones and skins of animals, usually cows and pigs. “Gelatin is a protein substance derived from collagen, a natural protein present in the tendons, ligaments, and tissues of mammals.
