What Makes Your Apples Out of This World

The goal of this experiment was to determine what chemical compounds are found in the Cosmic Crisp apple. To do this, the students used an extraction technique and freeze-dried the apples. A sample was taken prior to being freeze-dried and ran under gas chromatography-mass spectrometry (GCMS). Once the apples had been freeze-dried, they were then rehydrated, and another extraction experiment was done and ran again by GCMS. The results then showed what compounds make up the Cosmic Crisp apple.
