The Frying Stability of Oleogel Made from Rice Bran Wax and Sunflower Oil During Intermittent Frying of Potato Chips

Abstract

There is a need for an alternative method of producing a vegetable oil with high levels of unsaturated fatty acids and physical properties similar to solid fat. The objective of current work was to cut down the amount of oil absorbed by the finished product, increase the frying stability of sunflower oil, and fry potato chips using oleogel without harming their sensory quality. Rice bran wax was applied in this experiment, at rates of 2, 4, and 6 weight percent, and the generated oleogels were then utilized for four days in a succession to fry potato chips for four hours each day. The results suggested that potato chips could be fried using the sunflower oil-rice bran wax oleogel without having an adverse effect on their texture, color, or quality. Furthermore, the produced oleogel was more robust during frying than liquid sunflower oil. During intermittent frying, SFA levels also marginally rose in all samples with the exception of 4% oleogel. The control sample, which was sunflower oil, had the lowest levels of unsaturated fatty acids and poly unsaturated fatty acids at the end of the frying operation. The percentage of oil uptake by the potato chips in the oleogels containing 4 and 2% rice bran wax, on the other hand, was lower than in the control sample. The findings suggested that oleogels could be used as a deep-fat frying medium in household, commercial, and industrial settings.
