The production of trans-fats and the chemical changes in frying oils raise significant public health concerns, necessitating effective monitoring.
Researchers formulated canola oil mixed with different ratios of extra virgin olive oil and palm olein, identifying the best blend (67:22:11) by analyzing free fatty acid (FFA), peroxide value (PV), and iodine value (IV).
They utilized Fourier transform-infrared (FT-IR) spectroscopy and statistical methods to assess oil quality during multiple frying processes, finding that FT-IR can efficiently and noninvasively determine the quality of frying oils.
