摘要

An electronic nose based on an array of six coated piezoelectric quartz crystal (PZQ) sensors was presented with samples of used sunflower oil. To simulate the practice of frying food, sunflower oil was exposed to heat (170℃) and every 2 hours, a portion of potatoes were cooked in the oil. The oil was sampled every 8 h. and analysed by means of the electronic nose and chemical methods such as free fatty acid (FFA) test and the p-Anisidine determination.
