Description
The purpose of this experiment was to determine whether irradiation had an effect on the nutritive value of beef. My first hypothesis was that irradiated and nonirradiated beef would have the same amount protein and nitrogen. My second hypothesis was that the lipids in irradiated beef would be less than nonirradiated beef. The manipulated variable in this experiment was the irradiated ground beef. The responding variables in this experiment were the protein, nitrogen, and lipid content in the beef patties. To measure the responding variables, the protein and nitrogen was found by using a Licos machine. Protein was measured by percentage and nitrogen was unknown quantity. The lipids of the beef patties was measured by mL through sodium hydroxide.
