| In this paper, substitution of polar compound quantitation by quick
tests 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 obtained for polar
compounds indicated that OXIFRIT was the best quick tests as it gave the
minimum percentage of errors. Given the present situation, the application
of any of the two commercialized tests would contribute to improve frying
fat quality. |
