A new method was developed for the extraction of light filth from crushed red peppers. The method utilizes an isoprapanol defatting of the product followed by separation of light filth elements with mineral oil and n-heptane (85+15) in a 2 L trap flask. Collaborative studies resulted in good recoveries of light filth spike elements and clean extration papers. The method has been adopted as official first action.
开发了一种从碾碎的红辣椒中提取轻质杂质的新方法。该方法先对产品进行异丙醇脱脂，然后在2升分液漏斗中用矿物油和正庚烷（85 + 15）分离轻质杂质成分。协同研究得出轻质杂质添加成分的回收率良好，且提取滤纸干净。该方法已被采用为官方首次行动方法。
