III. Read the passage below and choose the correct answer for each question (5.0 points):
Gelatin is a protein substance that comes from the skins and bones of animals. Most people
know it as the substance used to make a jellylike salad or dessert. Not only is it useful in making
these foods, but it is also beneficial to the consumer because of its high protein content. Gelatin is
also commonly used in the photographic industry and in making medicinal capsules.
The process for producing gelatin is a long and complex one. In the processing of gelatin
made from bones (which varies slightly from that of gelatin made from skin), the grease first must be
eliminated. Then the bones are soaked in a solution of hydrochloric acid in order to rid them of
minerals and washed several times in water. Next, the bones are placed in distilled water, heated to
over 90 0 F for a few hours, placed in fresh distilled water, and then heated again at a little over 100 0 F.
A fluid forms from this heating, and it is concentrated, chilled, and sliced. Finally, it is dried and
ground. In its final form, gelatin is white, tasteless, and odorless.
