Green extraction methodologies using supercritical carbon dioxide (SC-CO) and subcritical water were used to valorize Conger myriaster skin (CMS). The omega-3 fatty acid content in CMS oil extracted using SC-CO was 18.62 ± 0.08%, and vitamin A, D, E, and K contents were 467.38 ± 0.46 μg/100 g, 8.31 ± 0.02 mg/100 g, 143.42 ± 4.61 mg/100 g, and 1.27 ± 0.05 mg/100 g, respectively. De-oiled CMS was hydrolyzed using subcritical water at temperatures ranging from 160 to 280 °C. Total protein, total sugar, and Maillard reaction product contents reached maximum values of 409.31 ± 2.86 mg bovine serum albumin (BSA)/g at 190 °C, 8.31 ± 0.31 mg glucose/g at 280 °C, and 0.240 ± 0.003 (Abs) at 220 °C, respectively. The highest antioxidant activity was observed at 280 °C. Free amino acids were abundant in the hydrolysates. Oil extraction from CMS using supercritical and subcritical fluids represents an effective and economical source of functional materials.
采用超临界二氧化碳（SC-CO）和亚临界水的绿色提取方法对星康吉鳗皮（CMS）进行增值利用。用SC-CO提取的CMS油中ω-3脂肪酸含量为18.62±0.08%，维生素A、D、E和K的含量分别为467.38±0.46μg/100g、8.31±0.02mg/100g、143.42±4.61mg/100g和1.27±0.05mg/100g。脱油后的CMS在160至280°C的温度下用亚临界水进行水解。总蛋白、总糖和美拉德反应产物含量分别在190°C时达到最大值409.31±2.86mg牛血清白蛋白（BSA）/g、280°C时达到8.31±0.31mg葡萄糖/g、220°C时达到0.240±0.003（吸光度）。在280°C时观察到最高的抗氧化活性。水解产物中游离氨基酸丰富。利用超临界和亚临界流体从CMS中提取油脂是一种有效且经济的功能材料来源。
