Paprika (Capsicum annuum L.) is a spice, utilized in culinary across the globe for its colour and pungency. A study was conducted to optimize the supercritical fluid extraction (SFE) process individually for selective extraction of paprika oil, capsaicin and pigments. Paprika oil was extracted by supercritical fluid—carbon dioxide at different process parameters: temperature (35‐75°C), pressure (100‐500 bar), extraction time (60‐180 minutes) and particle size (0.25‐1.25 mm) using central composite rotatable design (CCRD). The ANOVA results showed that yields of paprika oil, capsaicin and pigments were significantly (P ≤ .05) affected by the extraction process variables. Optimized SFE conditions, 65, 65 and 57.04°C temperature; 357.8, 200.62 and 400 bar pressure; 90, 90 and 100.89 minutes extraction time; and 0.78, 0.50 and 0.89 mm particle size, were obtained for optimum yield of paprika oil, capsaicin and pigments, respectively. Experimental yield of paprika oil, capsaicin and pigments at the optimized condition for respective compounds was 4.91% (w/w), 2.10% (w/w) and 16 319.9 NCV, and had good agreement with the predicted values. Antimicrobial activity of extracted paprika oil was found against E. coli, B. subtilus and S. aureus.

辣椒粉(辣椒油),辣椒素和色素的超临界萃取工艺优化

辣椒粉(Capsicum annuum L.)是一种香料,其颜色和辛辣度在全球范围内被广泛用于烹饪。进行了一项研究,以分别优化超临界流体萃取(SFE)工艺,以选择性萃取辣椒粉油,辣椒素和色素。辣椒粉油是通过超临界流体-二氧化碳在不同的工艺参数下提取的:使用温度(35-75°C),压力(100-500 bar),提取时间(60-180分钟)和粒径(0.25-1.25 mm)中央复合旋转设计(CCRD)。方差分析结果表明,辣椒粉油,辣椒素和色素的产量显着(P ≤.05)受提取过程变量的影响。优化的SFE条件,65、65和57.04°C温度; 357.8、200.62和400 bar压力;90、90和100.89分钟的提取时间;分别获得0.78、0.50和0.89 mm的粒径,以分别获得最佳的辣椒粉油,辣椒素和色素收率。在各化合物的最佳条件下,辣椒粉油,辣椒素和色素的实验产率分别为4.91%(w / w),2.10%(w / w)和16 319.9 NCV,与预测值具有良好的一致性。发现提取的辣椒粉对大肠杆菌枯草芽孢杆菌金黄色葡萄球菌具有抗菌活性。
