Abstract
Abstract A FAT SOLVENT IS PLACED WITHIN ONE COMPARTMENT OF A TEST RECEPTACLE; A SOLUTION OF AN INDICATOR AND SODIUM THIOSULFATE IS CONTAINED IN A SECOND COMPARTMENT. A PREDETERMINED AMOUNT OF POTASSIUM IODIDE IS ADDED TO THE SOLVENT. THE FAT IS THEN MIXED WITH THE SOLVENT. FINALLY, THE MIXTURE OF FAT AND SOLVENT IS MIXED WITH THE SODIUM THIOSULFATE AND INDICATOR SOLUTION. THE PRESENCE OF A DEEP BLUE COLOR INDICATES A PEROXIDE VALUE ABOVE THAT WHICH IS USABLE.
