Description
In this experiment, a steam distillation was performed to determine the effects that freeze drying would have on dill weed. The dill weed was chopped up and split into two different portions, freeze-dried and non-freeze dried. Both samples were boiled in water where the steam would travel to a separate vial for the vapor to be collected, containing a purified, liquid form of the components of dill weed and water. To separate the dill components from the water, the sample was then mixed with methylene chloride and the layer containing water was filtered out. The sample was then dried and prepped for Gas Chromatography Mass Spectrometry (GCMS) testing. The GCMS testing showed that the major elements that go into the smell and taste of dill weed were present in both freeze-dried and non-freeze dried.
