Extra-Virgin Olive Oil and Cheap Vegetable Oils: Distinction and Detection of Adulteration as Determined by GC and Chemometrics

摘要: Refined oils including corn, sunflower, soybean, and palm as well low-quality olive oil such refined lampante pomace are commonly used for extra-virgin (EVOO) adulteration. Indeed, K 270 could be a parameter the detection of EVOO fraud each type studied oils, 10 % olive, 4 % palm, 5 % 2 % soybean oils. Moreover, adulteration also detected by increase trans fatty acid contents with 3 % Actually, stigmasta-3,5-diene content is one most effective means detecting in at low levels: 0.4 % 1 % 0.2 % 0.5 % 0.1 % corn Finally, application linear discriminant analysis represent an alternative innovative tool faster cheaper evaluation
