UJI AKTIVITAS ANTIOKSIDAN SERBUK EKSTRAK BELIMBING WULUH (Averrhoa blimbi L.)

The Averrhoa Blimbi L. is spread all over in Indonesia as home garden plant. It has not been yet cultivated and developed its utilization. The utilization of this Averrhoa Blimbi L. that can be attempted is that as an instant powder. This fruit contains of chemical elements functioning as natural antioxidant. This study attempts to investigate the variation concentration of Averrhoa Blimbi L. extract on antioxidant activity by using DPPH (1, 1-difenil-2-pikrilhidrazil) method and UV-Vis spectrophotometer. Based on the result of the antioxidant activity test, it is found that different treatment shows different antioxidant activity. At concentration of Averrhoa Blimbi L.: sugar, Y1 (1:1) is -7.8%, Y2 (2:1) is -3.4%, and Y3 (4:1) is 48.4%. This indicates that the more the extract of Averrhoa Blimbi L. is added, the higher antioxidant activity is. The organoleptic test in this study includes colour, aroma, texture, and taste. The most preferred treatment is Y3 (Averrhoa Blimbi L.: sugar: = 4:1). The level of panelist acceptance score on the test parameter is shown as follows: the colour is 2.34 (bright yellow), the aroma is 2.45 (a little bit of sour aroma), the texture is 2.21 (smooth), and the taste is 2.15 (sweet and a bit of sour).
