This study was designed to investigate the effect of $\beta-carotene$ on the heat oxidation stability of deep fried laid with different healing temperature. Commercially purchased $\beta-carotene$ was used to this experiment $\beta-carotene$ was added to the deep fried lard at final concentration of $0\%\;0.001\%\;and\;0.004\%$ (wt/wt fat basis). Total plate count peroxide value, acid value, and TBA(thiobarbituric acid) values of the samples were determined regulary at $50^{\circ}C$ during 15 days. The result of the study are as follows: The number of microorganism was decreased by $\beta-carotene$ added to the deep fried lard Deep fried lard with $0.004\%$ $\beta-carotene$ have higher antioxidative effect than those of control and $0.001\%$ treated group. Peroxide and TBA values were significantly (P<0.05) decreased in all samples by added $\beta-carotene$ at $0.004\%$ Antioxidative effect increased with increasing concentration of $\beta-carotene$. These results suggest that $\beta-carotene$ might inhibit the growth of microganisms and retard lipid oxidation in the deep fried lard.
