This study aimed was to determine the effect of roselle flour extract on pork jerky. Completely randomized design 4 x 3 was used in this experiment The treatment consisted of ER0 = without addition of roselle flour extract, ER4 = 4% (v/w) roselle flour extract, ER8 = roselle flour extract 8% (v/w) and ER12 = roselle flour extract 12%(v/w). The parameters observed were water content, fat oxidation, total bacteria, ph and organoleptic: color, aroma, and taste of park jerky. The result of statistical analysis showed that rosela flour exract on pork jerky had highly significantly effect (P<0.01) on water, fat oxidation, pH and organoleptics: colors, the aroma of pork jerky. The lowest water content was in ER12 (35.86±0.33), the lowest fat oxidation was in the ER12 (9.57±0.70), the lowest pH was in ER4 (4.79±0.05). The best color was found in ER4 (4.86±0.38), the best aroma was found in ER0 (5.00±0.00). In conclusion, increasing of roselle flour extract level causes the decreasing the oxidation fat, reducing the color score ( jerky become brown) and rosela/ sour in aroma.
