Abstract:This study was conducted to enhance the quality of deteriorated frying oils by employing various types of adsorbents. Four vegetable oils�sunflower, soybean, rice bran, and palm olein oil�whose quality deteriorated after deep frying, were treated with six adsorbents�activated carbon, Fuller's earth, ash, silica gel, aluminum hydroxide gel, and magnesium oxide�at 150 °C for 30 min to reduce the already elevated free fatty acid (FFA %), peroxide value (PV), total polar material (TPM), p-anisidine value (p-AV), a… Show more
