title: New brine saturation technique for the extraction of light filth from rubbed sage, paprika, and corn meal: intralaboratory study.
abstract: A new and widely applicable technique for the isolation of light filth from food has been developed. It includes a simple alcohol defatting followed by a brine saturation of the product by heating and cooling and a subsequent trapping of the filth elements with olive oil and tap water. The methods circumvent the use of hazardous and expensive solvents and lengthy defatting and/or pre-treatment procedures. In an intralaboratory study, recoveries of elytral squares and rodent hair fragments added to paprika, rubbed sage, and corn meal ranged from 95.8 to 100%.
