Moreover, the system allows to perform an utmost accurate analysis of an oil thanks to the p-Anisidine Value test , which is the parameter indicating the secondary
This study was conducted to investigate the condition of frying oil used for frying chicken nuggets in a deep fryer. The acidification of the frying oils used, soybean oil (SB), canola oil (CA), palm oil (PA), and lard (LA), were determined as peroxide value, acid value, and fatty acid composition, after chicken nuggets were fried in them for 101 times.

The new monitors are designed to measure total polar materials in frying oil. Polar materials may be defined simply as all non-triglycerides in cooking oil. Fresh oils, prior to the initiation of frying, usually contain 2 to 4 percent polar materials. Once frying starts, oils begin to degrade, a process that is irreversible.

Frying oil degrades during frying, sometimes rapidly and sometimes slowly. The relative amounts of various degradation products that accumulate in the oil vary substantially with conditions and the reasons for this are not well understood. The purpose is to better understand oil degradation during frying, so that the oil stability and food quality can be improved.
