Abstract
An official first action method for the extraction of light filth from spices, 44.A03--44.A05, was modified for the analyses of ground paprika. The sample is extracted with isopropanol and light filth is isolated from 40% isopropanol with mineral oil. Eight collaborators analyzed 4 paprika samples, 2 by the official method and 2 by the proposed method. Average recoveries of added elytral squares were 97 and 66%, respectively, for the proposed and official methods. Recoveries of added rodent hairs were 94 and 61%, respectively. The method has been adopted as official first action for the extraction of light filth from ground paprika.
