PENGARUH PEMBERIAN EKSTRAK TEPUNG ROSELA (Hibiscus sabdarifa Linn) TERHADAP SIFAT FISIK DAN KIMIA DENDENG BABI (The effect of roselle flour extract (hibiscus sabdariff linn) on the physical and chemical characteristics of pork jerky)

Abstract

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.
