Deep fried instant noodles, biscuits, and cookies were prepared, using the same beef tallow as their fat ingredient. In addition to wheat flour and beef tallow, the common and major ingredients, the deep fried instant noodle contained 1.5% salt before frying, the biscuits 20.0% sucrose and 10.0% nonfat milk solid before baking, and the cookies 20.0% sucrose before baking. The three products and a portion of beef tallow, which was to be used as control, were stored in an incubator at $47.0{\pm}1.5^{\circ}C$. The peroxide value and the free fatty acid value of the control and the extracted fat were determined regularly during the storage period. The fat incorporated in the biscuits exhibited far greater stability to rancidity development than that of the control with regard to both peroxide value and free fatty acid value development. However, the fat incorporated in the deep fried instant noodles and the cookies showed much poorer stability than that of the control. Factors like a deep frying process and/or the presence of a significant amount of salt in the deep fried instant noodles appeared to promote the rancidity development of the fat incorporated in the product. On the other hand, Maillard type browning reaction products in the biscuits seemed to retard effectively the rancidity development of the fat incorporated in the product.
