Description
In the Organic Chemistry I lab, overseen by Dr. Watson, research was carried out to investigate the effects of freeze drying on fennel using Gas Chromatography-Mass Spectrometry (GCMS). Freeze drying, popularly used in agriculture, pharmaceutical, and aerospace fields, offers users the ability to prolong the shelf-life of foods at a lighter mass. Both fresh and processed samples were compared to evaluate the compound changes observed through GCMS, ultimately pointing out that freeze drying can retain important flavor compounds of fennel. During the analysis, a peak indicative of contamination introduced during sample preparation highlights the sensitivity of techniques and the importance of maintaining strict laboratory practices.
