The effect of three different synthetic antioxidants viz.-Tertiary Butylated Hydroxyquinone (TBHQ), Butylated Hydroxyanisole (BHA), Butylated hydroxyquinone (BHT) in the stability of palm oil on deep fat frying of instant noodles was well studied at ambient condition taking peroxide value and acid value as the objective parameters to measure the oxidation of frying oil. Soaked cake(cut noodles with soup) as frying samples were taken then fried in Refined Bleached Deodorized (RBD) palm oil of standard grade at 170 - 180°C. The RBD palm oil was analyzed for its physiochemical parameters. The fried noodles were also analyzed for moisture content, acid value (AV), peroxide value (PV), density (gm/cc). The three synthetic antioxidants in their proportion 100 ppm, 150 ppm, 200 ppm mixed in RBD palm oil in three batches. Oil sample collected in each hour of frying, it was found that higher the proportion of antioxidants lesser was the oxidation of frying oil which increased the stability. For three antioxidants the frying quality was analyzed such as AV, PV, and specific gravity and control sample oil was taken as without using antioxidant. The results showed that TBHQ of 150 ppm was statistically positive significance over two antioxidants (BHA and BHT) on the basis of AV and specific gravity where correlation coefficient (r), r > 6 PE. In case of BHA and BHT while using 200 ppm it extended the stability of frying oil upto 14 and 16 hrs respectively on the basis of AV. It was statically positive significant (r > 6PE) but in case of PV it extended upto 12 hr and 14 hr which was not statistically positive significance where r < 6PE. In conclusion 150 ppm of TBHQ was more significance over BHA and BHT to control the oxidation of oil on the basis of PV, AV and specific gravity.
