---

This study aim was to get the best concentration of red galangal extract in
edible coating of Meranti sago starch as an antioxidant in peeled malang apples.
This research method used an experimental method, using a completely
randomized design (CRD) which consist of five treatments and three replication
to obtain 15 experimental units. The treatments in this study were P0 (0% red
galangal extract), P1 (1% red galangal extract), P2 (3% red galangal extract), P3
(5% red galangal extract), and P4 (7% red galangal extract) in edible coating
meranti sago starch formulation which applied to the peeled malang apples and
stored for 8 days. The parameter observed in edible coating was antioxidant
activity. The parameters observed in peeled malang apples were weight loss, total
dissolved solid, vitamin C, browning index, descriptive and hedonic sensory test
of color, hardness, taste and flavor. Data were analyzed statistically using
analysis of variance (ANOVA) and continued with DNMRT at 5% level. The
chosen treatment was 7% red galangal extract concentration with IC50 of 158.41
μg/ml. On the 8th day the peeled apples had 45,40% weight loss, 1.40°brix total
dissolved solids, 3.64 mg/100g vitamin C, and 936.05 browning index. The
results of sensory assessment of the peeled apples on colour was 2.70 (brownish
white), hardness was 2.67 (mildly soft), taste was 3.53 (typical of galanga and
apple taste), and flavor was 3.27 (typical of galangal and apple flavor). The
hedonic sensory assessment of the peeled apples on colour was 2.69 (rather like),
hardness was 2.78 (rather like), taste was 3.01 (rather like), and flavor was 3.00
(rather like).
Keywords: Edible coating, red galangal extract, peeled apples
