The purpose of this experiment
was to find out whether the new vegetable cellulose-based capsules
would dissolve differently than the long existing animal gelatin-based
capsules. This experiment was conducted to test the effects of
two variables, temperature and pH, on both types of capsules.
The experiment tested the dissolution of both capsules in liquid
at three different temperatures and three different pH levels,
including body temperature and the normal stomach acid pH. The
capsules were filled with red Jell-O crystals, and the time to
the release of red color from the filled capsules was measured.
The data indicates that the dissolution is dependent upon temperature
and independent of the pH level in both types of capsules. There
was significantly faster dissolution as the temperature of the
liquids was increased, but there is little difference between
different pHs at the same temperature. In addition, the vegetable
capsules are less variable at different temperatures that the
gelatin capsules. The data shows that people can take the vegetable
capsules without worrying about their ingredients or their effectiveness.
