Mystery Food Investigation
ntroduction
In this experiment we created standards to be able to compare a mystery substance off of. We were tasked to investigate a murder that took place by analyzing a man's last meal to find out where he had ate based on the content of his stomach. Before we could test the mystery substance we had to establish standards, so we could compare off of them. Based on the results of this lab, we believed that the victim last ate at Buffalo Wild Wings (Veliz).
Methods and Materials
We started this lab off with establishing our standards, we completed 4 tests to determine how items will appear with and without certain macromolecules. We did not have a working Sudan so we had to switch to the paper bag method. Instead of adding 5 drops of Sudan IV, waiting 5 minutes and shaking to see the results, we smeared the substances on a paper bag and waited to see how they would react.

We were able to determine this by the presence of simple sugar, protein and lipids which are all found in a typical meal at Buffalo Wild Wings. The way we could so easily determine this is through the standards we have established so we were able to compare our mystery meal substance to a constant. Even though we did not have a working Sudan IV in this lab we found an alternative to figuring it all out even though having it would have been nice. I personally believe these test can definitely help in the forensic field when determining parts of a crime. Below our the stands we established along with how our victims dinner held. The meal turned orange in the simple sugar test determining that it was in fact present, yet red in complex sugar determining there wasn't any. Then lilac in our protein test and the substance just sat on top of the brown paper bag in the lipid test making it positive in both proteins and
