闪式提取辣椒渣黄酮及总酚的工艺研究

Study on flavonoid and total phenol extraction from capsicum residual by blitzkrieg extraction

摘要: 干红辣椒经色素和辣椒碱类物质提取后的残余物称为辣椒渣。以辣椒渣为原料,甲醇为溶剂,闪式提取黄酮及总酚类化合物,通过正交实验优化得到的最佳工艺条件为:50%甲醇溶液,闪提转速4400r/min,闪提时间150s,在此条件下,黄酮及总酚的得率分别为(3.07±0.05)mgRE(芦丁)/g和(9.61±0.12)mgGAE(没食子酸)/g。采用HPLC法鉴定出辣椒渣甲醇提取物中含槲皮素和咖啡酸。

Abstract: After separation of capsanthin and capsaicin from dry red pepper, the substance left behind was called capsicum residual.Using capsicum residual as raw material, methanol as extraction solvent, blitzkrieg extraction was assisted to extract flavonoid and total phenol.Optimal conditions were determined by orthogonal experiment, the result was: concentration of methanol was 50%, extraction revolution 4400r /min, extraction time 150s, under these conditions, extraction yield of flavonoid and total phenol were ( 3.07 ± 0.05) mgRE/g and ( 9.61 ± 0.12) mgGAE/g respectively.In methanol extracts, quercetin and caffeic acid were identified by HPLC.
