Abstract:
Supercritical Fluid Extraction (SCFE), a prominent technique utilized for the extraction of essential oils from plant materials; that offers several advantages than conventional extraction methods like distillation or solvent extraction. For instance, they provide enhanced extraction efficiency, shorter extraction duration, preservation of oil quality and aroma, and reduced environmental impact. Here we have reported an optimization study that was conducted at the Pilot Scale for the Supercritical Fluid Extraction (SCFE) of ginger oil from ginger oleoresin. This study aimed to investigate the influence of extraction temperature, extraction pressure, and CO2 flow rate on the yield of gingerol compounds, particularly 6-gingerol, and total gingerol [1]. Additionally, different absorbents, namely activated charcoal and Polyacrylamide-coated Silica, were introduced into the extraction column to assess their impact on the extraction process. The results revealed that incorporating Polyacrylamide-coated Silica as an absorbent in the extraction column yielded the highest percentage of 6-gingerol and total gingerol content. Conversely, the lowest values were observed in the absence of an absorbent. Optimal conditions [2] for achieving maximum 6-gingerol (36.7%) and total gingerol (53.04%) content were determined to be within the range of 40°C to 60°C temperature and 150 to 250 bar pressure during SCFE. The quantification of 6-gingerol and total gingerol content was performed using High-Performance Liquid Chromatography (HPLC), providing reliable experimental data for analysis and comparison. Overall, these findings underscore the efficacy of SCFE coupled with Polyacrylamide-coated Silica as an absorbent for the extraction of ginger oil, offering potential applications in industries such as food, cosmetics, and pharmaceuticals
