Description
Honeycrisp apples were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) both before and after undergoing a freeze-drying process to examine the impact on their chemical composition. The GC-MS analysis of the fresh apple sample revealed the presence of various lipid-based compounds. These compounds were largely absent in the freeze-dried sample, suggesting that the freeze-drying process significantly removed many of the lipids from the fruit. In contrast, the GC-MS analysis of the freeze-dried sample revealed the presence of numerous compounds typically associated with aroma and flavor. Indicating that, while freeze-drying removed many of the lipid components, it has preserved and possibly even concentrated the compounds that are important for the apple’s sensory qualities. The results highlight the dynamic changes that occur in the chemical composition of Honeycrisp apples due to the freeze-drying process, with particular emphasis on the loss of fatty acids and the preservation of key aroma and flavor compounds.
