The aim of this study was to evaluate the effects of a natural antioxidant derived from rosemary extract on the stabilization of palmolein oil during deep-fat frying of Noodles. Palmolein oil with tertiary butylhydroquinone (TBHQ), a synthetic antioxidant and palmolein without antioxidant were used as positive controls. Thermo-oxidative transformation were measured according to various physical and chemical parameters. Total polar compounds (TPC), free fatty acids (FFA) were measured during the study. All the parameters evaluated in the study increased with the number of frying cycles. The order of effectiveness of antioxidants for inhibition of palmolein oil degradation in deep-noodles was: PRESOL (rosemary based extract) > TBHQ > Control. In terms of oil consumption, it was observed that noodles fried in oil with rosemary extract had lower value of oil consumption as compared to TBHQ and control. The TBHQ degradation kinetics was also evaluated with frying cycle. It showed an exponential decay with increase in frying cycles. Also samples containing natural antioxidant had a least changes in the colour as compared to TBHQ and control at the end of frying cycle.
