Abstract
In this paper, substitution of polar compound quantitation by quick te sts for discarding used frying fats according to official regulation, is evaluated. Two commercialized tests (VERI-FRY and OXIFRIT) as well as two laboratory tests (PEREVALOV and Solubility in acetone:methanol 90:10) have been applied. Comparison of the results with those obtaine d for polar compounds indicated that OXIFRIT was the best quick tests as it gave the minimum percentage of errors. Given tile present situat ion, the application of any of the two commercialized tests would cont ribute to improve frying fat quality.
