This study explores the adsorptive bleaching potential of glucose-sourced activated carbon on palm and olive oils, exploring its effectiveness in pigment removal across various adsorbent concentrations. Distinct adsorption trends were observed, with higher adsorbent concentrations achieving more efficient bleaching in both oils. For palm oil, a maximum pigment removal of 35.4% was achieved at 3.0 g of adsorbent, while lower concentrations showed reduced efficiency. Olive oil demonstrated a higher bleaching effect, with 64.9% pigment removal at 3.0 g, likely due to its lighter initial color. Adsorption efficiency trends fit well with the Langmuir isotherm model, indicating monolayer adsorption. Langmuir parameters further showed that glucose-sourced activated carbon exhibited a stronger affinity for pigments in palm oil than in olive oil, though effective in both cases. These results highlight glucose-sourced activated carbon as a promising, sustainable adsorbent for industrial oil refining. By utilizing renewable resources, this study aligns with the Sustainable Development Goals (SDGs) 7 (Affordable and Clean Energy) and 12 (Responsible Consumption and Production), emphasizing eco-friendly practices in food processing.
