Description
Common ginger (Zingiber officinale) was analyzed to evaluate the retention of bioactive compounds following steam distillation and freeze drying. Fresh ginger samples were first subjected to steam distillation and liquid-liquid extraction (LLE). The resulting organic layer was analyzed using gas chromatography-mass spectrometry (GC-MS) to establish a baseline chemical profile of bioactive compounds present after distillation. Freeze-dried ginger samples were then processed under the same steam distillation and LLE conditions to ensure consistency. The resulting organic extracts were analyzed using GC-MS, and their chemical profiles were compared to those of the fresh ginger samples. The comparison showed that bioactive compounds associated with antifungal, anti-inflammatory, analgesic, anxiolytic, and anticonvulsant properties were detected in both sample sets, indicating their retention after freeze drying and subsequent steam distillation. These results indicate that freeze drying does not significantly affect the retention of ginger’s bioactive compounds and serves as an effective processing and preservation method for maintaining its chemical composition and potential health-related properties.
