| 摘 要： | 以红辣椒粉为原料,采用超临界CO2萃取法提取辣椒油树脂。以辣椒油树脂的收率为评价指标,确定最佳工艺条件为:萃取压力25MPa,萃取温度30℃,萃取时间3h,此条件下辣椒油树脂收率为10.09%±0.29%。对比实验结果显示:超临界CO2法所得的辣椒油树脂的色价为303±5,辣椒素质量浓度为3.7%±0.7%,均明显优于传统的索氏提取法。对超临界CO2法所得的辣椒油树脂进行二次超临界萃取,可将辣椒红色素和辣椒素进行初步分离。

| Abstract: | Supercritical carbon dioxide was applied in the extraction of capsicum oleoresin with the red capsicum’s smash as the raw material.With the yield of capsicum oleoresin as an index,the optimal conditions were as follows:pressure(25MPa),temperature(30℃),time(3h),and the extraction rate of capsicum oleoresin up to 10.09%±0.29%.Under the conditions,the color value of the capsicum oleoresin extracted by supercritical carbon dioxide was 303±5 and the mass concentration of capsaicin was 3.7%±0.7%,obviously better than that from soxhlet extraction.With the capsicum oleoresin extracted by supercritical carbon dioxide as the material,the capsicum red pigment and the capsaicin could be primarily separated by another supercritical carbon dioxide extraction. |
